10Gig - GBIC module, can we connect?

Hi,
I have a PIX 535 firewall which has GBIC module and I need to connect to a Switch 2360 / 2960 which has 10 Gig SFP.
Can I connect using multimode fiber. Will it work?
Or is there any Speed configuration we can do to reduce 10 Gig to 1 Gig in the switch side?
Thanks & REgards,

Hi I beleive the PIX interface is fixed at 1GigE and with a 10GE SFP in the switch this configuration won't work, you need to ensure the devices are matched for the same speed and media type Multi Mode (MM) or Single Mode (SM).
I beleive the PIX GE interface is MM so you will need to install an MM 1GE SFP into the switch don't forget that you will also need a GigE Failover Link if you are using PIX Failover.

Optical Fiber connection between GBIC module and SFP module

Hi
I am in need of help.
I have a 3750 24TS-S, 2 port SFP, switch at the edge. And i have a 4507R switch at the Distribution layer. In 4507 switch I have WS-X4515 Sup IV supervisor engine with 2 GBIC Port and also have WS-4306-GB 6 port GBIC module. I am using WS-G5486 Single mode connector, LX/LH tranceiver to connect to this port.
This is the scenario.. i want to know is it posible to conect one end of the fiber cable to connect to a SFP Module ( 3750-24TS-S, 2 Port SFP) and other end ( WS-X4515 Sup IV supervisor engine with 2 GBIC Port or WS-4306-GB 6 port GBIC module) at the WS-G5486 Single mode LX/LH connector ?????
Plz let me now asap.. i need to give a solution imdtly.
Thanks & regards

Discussion is never a problem ....;-}
The issue is that the signal is "too loud" and is distorted (or, more correctly, is so loud it overloads the receiver).
The operational envelope for nearly every receiver of any kind includes a bottom number (too weak to hear) and a top number (too loud to understand).
As an example, think about an system where you have a hearing aid that would let you hear someone speaking in a normal voice from 100 feet away ... then having someone scream the same words into the hearing aid from 6 inches away ... the sound would be distorted and you would have difficulty understanding them ... after a while, you'd begein to go deaf and eventually, it would sound normal (until you became completely deaf).
So, what you need to do is look at the transmitter power, and the envelope/range of acceptable power the receiver can hear.
Normally that difference is the optical budget ... given the loss numbers of the media between the two, you can determine if you have enough power to make the trip.
In a Lab environment, you still have to hit the receiver's budget number, but from the other end (the "too high" side).
If you know the transmitter puts out X, and the receiver can accept from Y to (X-50), then you need to add enough attenuation to get X down to (X-50)or lower (but still more than Y).
When you have a transmitter powerful enough to drive tens of kilometers, putting one two meters away from the receiver will pretty much guarantee a burnout (unless you install optical attenuation).
Good Luck

WS-X4306-GB - Catalyst 4500 6-port GBIC Module & FC Tape Libraries

WS-X4306-GB - Catalyst 4500 6-port GBIC Module & FC Tape Libraries
I have several Tape Autoloader Libraries from Dell which have Fibre Channel interfaces. I have loop switches that these connect to today. I also have a Catalyst 4506 with a WS-X4306-GB - 6-port GBIC Module. I would like to use the X4306 as a loop switch. Some of the libraries can also connect via point-to-point FC.
Can this be done? If yes, how do I start in making this happen?
Thank You.

Sorry but the Catalyst 4500 does not support Fibre Channel connections on the WS-X4306-GB (or on any card). It's strictly an Ethernet switch. Reference
To mix and match Ethernet and FC interfaces, you'd have to be on a new platform like the Nexus 5k series - specifically the UP (Unified Port) variants.

Gbic module for SGE2000

Hello, I need to know which gbic modules are compatible SGE2000P SGE2000 and if I can connect those with a switch that has a module SRW2008P with MGBSX1.

I found an old Linksys manual (attached) for the SGE2000/200P switches. The SFPs that the system supports are as follows:
"Use the Linksys MGBT1, MGBSX1, or MGBLH1 mini-GBIC modules
with the Switch. The MGBSX1 and the MGBLH1 require fiber cabling
with LC connectors, while the MGBT1 requires a Category 5e Ethernet
cable with an RJ-45 connector."
Shouldn't be any problem connecting the two switches via MGBSX1 interfaces.
Hope this helps!

After update I can't connect to the internet in no way, shape or form

I rarely update because: 1) something always breaks when you update (like now) and 2) I don't like to deal with new crap like GNOME 3. Anyway:
I bought a new router (TL-WR1043N) and configured it with an old Ubuntu because connecting to 192.168.1.1 didn't work on any of my Arch Linux installations. Now... here's where it all starts... I can't use the 'n' wireless on my laptop since I have to install something to use WPA, and to install that I need to update, but I don't want to deal with GNOME 3 and Firefox >3. But I gave up eventually gave up and connected my laptop to the router by Ethernet cable. Setting that up was very easy: 'ifconfig eth0 up; dhcpcd'. Voila! I updated my whole system and restarted. To see how badly I damaged my system I opened Nautilus (I use Openbox with some GNOME programs): shock and dismay, the fonts are visible from the moon. I guess I'll have to quit using GNOME programs completely now but I expected that. I used to use KDE back in the day and when KDE4 came forth from that unholy pit, I immediately abandoned it for GNOME. This time we had more time to prepare, everybody knew what GNOME 3 was going to be. I started using Openbox quite a long time ago.
Anyway: Now to fix my wireless right? WRONG! I can't connect to the internet on cable to get the packages for wireless. I installed Windows 7 64 on the same laptop and it connects to the cable. Ubuntu 9.10 Live also connects, but due to the changes of rc.conf and network stuff I can't connect at all with Arch Linux.
So I decided to abandon it completely and reinstall from scratch. But the Live CD also doesn't work. With all the ways I've tried it all comes down to this:
dhcpcd always times out waiting for a carrier and 'ip addr' shows 'eth0: <NO-CARRIER, ....' if the interface is up. I'm not sure what information I should give you, but I can't paste any here since I can't connect to the damn internet on that laptop.
About the router: the cable is plugged on port 1 and the LED for it flashes if I reboot the computer. In Windows it stops flashing while it connects and flashes again when connected. I removed 'network' from DAEMONS and it flashes till I start it with '/etc/rc.d/network start'. This hangs for a while and returns '[DONE]' even though it doesn't work and the LED never flashes again on the router.
In rc.conf I have exactly what the example says for DHCP. In any case, it doesn't work with the Live CD either.
EDIT 1: From lscpi: painstakingly typed:
06:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
07:00.0 Ethernet controller: Realtek Semiconducctor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
EDIT 2: Just to be clear: I can use the wireless on the laptop on the Live CD, but I want to use the cable because of the greater speed (94Mbit/s on cable 60 something on wireless n, 20 something on g) and because I rarely move the laptop.
EDIT 3: lspci -v shows "Kernel driver in use: r8169 / Kernel modules: r8169", so the driver is loaded.
EDIT 4: So if I boot from the CD. ip addr shows:
eth: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 00:1d:92:...etc... brd ff:ff:ff:ff:ff:ff
And the LED flashes. When I type: "ifconfig eth0 up" it stops, never to light up again and ip addr shows: "eth: <nO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000

When you're in Arch, use output redirection
lspci >lspci.out
then boot into Ubuntu or something where you can access the files and the BBS, Of course, don't forget to use a new file for each command output.
The new network config in rc.conf is not that complicated (wired anyway; never used wireless). OTOH I've had issues on two machines where I have to restart the network daemon (rc.d restart network) or rerun netcfg (netcfg eth0) after boot to get connectivity. And I still haven't come to grips with the ip command.

Upraded Sql Developer and can't connect to Oracle

I just updated to the Dec 2009 release and now I can't connect
When I click the plus or right click on Connections and select "New Connection" nothing happens.
If I monitor processes in task manager it shows a brief spike in cpus and a small increase in memory usage but nothing happens in the app.
I also noticed that when I close the application it does not leave memory. I have to kill the process via the task manager to get rid of it.
If I go back to version 1.5.1 it works fine. It also leaves memory when terminated
Using winxp r3.

How can i connect between WS−G5484 1000BASE−SX and GLC-LH-SMD ?

Dear experts,
My customer has 6509 A-side and B-side core switches and need to migrate only 6509 B-side to Nexus.
I have some question below.
1. Customer's 6509A-side has multiple WS−G5484 1000BASE−SX and WS−G5486 1000BASE−LX links and it is connected to 6509B-side.
But customer bought only GLC-LH-SMD for Nexus migration of 6509B-side.
I understood BLC-LH-SMD doesn't support SX type, so I am worndering how i can connect between 2 different module ?
Or should i have GLC-SX-MMD for WS−G5484 1000BASE−SX links ?
2. Current Rack has LC type patch pannel from B-side to Rack A side.
But new Nexus A-side rack is located at different row and between these rack, there is only sc-type patch pannel.
So If i want to connect from LC-type to Sc-type patch pannel, how can i connect ? do i have to use SC-LC converter ?
3. Old 6509 links use many MMF cable, and new Nexus use SMF.
Between same LX/LH links, if a side use MMF and another side use SMF, how can i connect each other ?
Again new Nexus A-side rack is located at different row and between these rack, there is only sc-type patch pannel.
Please let me know in detail, Thanks in advance, I really appreciate for your help.
Jason.

Hi Leo,
Thanks of your reply.
Dear Experts,
I seek your expert's advice for another question urgently.
Please make you time and share your experiecce.
Thanks.

[SOLVED] Intel 7260 Vaio can't connect to wifi

Hi there,
First off, I should mention that I know my way around Linux but I'm pretty new to Arch, so there might be things that I know that don't apply here.
So, I have this problem with this network, I can't connect to it and frankly I don't know why. I was on Ubuntu until a few days ago and I still had the problem. I posted on the Ubuntu forum >>here<< and I was told to upgrade, but as I've been willing to move to Arch for quite some time, I thought that was maybe the time. BUT, the problem is still there, which worries me.
To sum it up, about one or two weeks ago, I was connecting fine to this network (ZyXEL) and then after a reboot, no way to connect to it, no matter what I try. I have noticed an error message that keeps coming back all the time (see below) and the wifi indicator in i3status sometimes flashes me with an IP while I'm trying to connect then eventually the network disappears (not with wicd, only nm). Those are basically the symptoms.

I have had troubles with the wifi in the past (from what I read on the internet, this card is not yet fully supported everywhere) but nothing like this. Usually, disconnecting and reconnecting did the trick, sometimes I had to restart NetworkManager in extreme cases, but nothing more.
I tried a lot of things (modprobe, rfkill, firmware update, etc), rebooted everything I could but couldn't do anything. I have found bug reports and forums posts of similar problems but the solutions there either didn't work for me or the problem just seem to have disappeared for some people. I read that this card was not really supported before the kernel 3.11 or 3.13 but now I have 3.16 and it's still there. What's really bugging me is that I could successfully connect to this network a couple weeks ago...
On the Ubuntu forum, they have a script that displays useful information when posting about wireless problems. I have taken off the Ubuntu specific bits and I think this will save you some time asking me to run commands. One thing is not mentioned in the script: I use wicd.

I have the exact same problem, appeared completely random. I had several restarts this Christmas on the laptop, even after upgrades. I blamed the ath driver. But I noticed when I restart the router by plugging out it from the wall, then in again, sometimes it's working.
I carefully changed every possible settings in the router, then I found if I disable IPv6 (yes, it's capable of that despite Sky does not provide IPv6 service) it started to work even after multiple reboots. It took mi a while since the new year.
I'm using connman and when it was wrong, connman was completely frozen. If I entered "connmanctl scan wifi", it never quit. Same for "connmanctl state".
I also noticed that the router LED was blinking continuously and on the laptop when I checked the connection status with ifconfig it showed very high usage of TX packets. It also blocked the whole wifi, so my phone was not able to access the internet. Strange problem, I'm unsure what caused it and not quite sure how disabling IPv6 solved it. But I'm also afraid that maybe somewhere else I can't disable IPv6 on the router.

Any idea why this exception thrown ? Is this because of weblogic server connections cleanup or something to do with connections? As per my understanding , JDBC connection will not be released when AM is active/managed mode. Oracle Doc says
" That application module instance holds onto the JDBC connection object that it acquired from the pool until the application module instance is removed from the application module pool."

jbo.ampool.maxinactiveage is set to 20 min which means that If AM in the pool is inactive for 20 min then clean this AM in the next cycle (still that is not our case). We also set jbo.recyclethreshold="50" means 50 AMs can exists in the pool with managed-state. We set these because of performance reasons. As per my understanding, AM instance will be deleted (????) but in any action on the UI will pick up another instance of the AM because datacontrolframe is still valid in the session. Do we have any best practice like jbo.ampool.maxinactiveage should be equal to session time out?. The error seems AM lost the underlying JDBC connection and somehow application is using that stale AM ?. what will be possible reason?.

Can't connect to any wifi signal

I have a Lenovo S10 Ideapad. The wifi used to work fine for a long time under the broadcom-wl driver but after updating my severely outdated netbook, it doesn't anymore. The wl module ruins the network connection (wired and wireless). So I read that the b43 driver would be better to use, so I install it along with the b43fwcutter and to my surprise, wicd was able to see the network signals around me. Unfortunately, it can't connect to anything WPA secured, WEP secured or completely unsecured. If it isn't a bad password, then it fails to get the IP address. So I switched over to networkmanager and even that refuses to connect to any wireless signal.
Yes, I've read the wikis and have tried everything short of praying to a god for guidance.
I think the problem can be traced back to the shitty drivers which would mean I'm shit out of luck but if anyone knows a way to fix this, please tell me. I really don't want to have to go to Ubuntu to use my netbook outside my own home (not that theres anything wrong with Ubuntu but Arch is my true love).

What version of b43fwcutter did you use?
What is the specific Broadcom chip you have?
My system:

Application module is not connected to a database

Using JDev 11.1.1.3
I have an application that uses EJB and i have an application that uses business components. The EJB app needs to integrate some parts from the BC application so i package the BC model in a jar file and use it in my EJB to create some records.
This is some code that i execute in my EJB to create a new record using the BC jar:
ApplicationModule module = Configuration.createRootApplicationModule("bcApp.model.MyModuleImpl", "MyModuleLocal");
am = (MyModuleImpl)module;
BillDefImpl billDef = (BillDefImpl)BillImpl.getDefinitionObject();
bill = (BillImpl)billDef.createInstance2(am.getDBTransaction(), null);
//set some attributes
EntityDefImpl billLineDef = BillLineImpl.getDefinitionObject();
BillLineImpl billLine = (BillLineImpl)billLineDef.createInstance2(am.getDBTransaction(),null);
billLine.setBill(bill);
//set some attributes
am.getTransaction().commit();The weird behavior of this is that the first time i call this code, everything is working just fine. Both the bill and billLine are created in the database. No error shows up in the console.
When i try to do the exact same in the same session, i get the "Application module is not connected to a databas" error. When i open a new session, everything is working fine again.
I also tried using the am.getDBTransaction().commit(); instead of the getTransaction.
Can anybody tell me what could cause this kind of behavior? Am i doing something wrong?

Sorry, just a typo. I modified the classes/package for this post.
I also did some more testing and it appears to be EJB related. The code i provided above is called from an EJB. When I execute the code from a managed bean, i don't get this error when i execute it a second time.
Maybe also useful info. My application module uses a JNDI data source that is configured on the weblogic server.

Can I connect a single fp-1001 to two fp-1000's each on seperate cpu's?

Is it possible to poll a single FP1001 from two computers using an FP1000 on each of the computers?

Hi Aaron,
sorry, you're wrong.

Have a look at the description. This is as its written in the EIA Catalog
(Electronics Industries Alliance Standards and Engineering Publications).
This Publication is for free: http://www.tiaonline.org
The complete Standard papers can be bought for the price at the end of the
next paragraph.
TIA/EIA-485-A
Electrical Characteristics of Generators and Receivers for Use in Balanced
Digital Multipoint Systems.
(ANSI/TIA/EIA-485-A-98)
This Standard specifies the electrical characteristics of generators and
receivers that may be employed when specified for the interchange of
binary signals in multipoint interconnection of digital equipment. When
implemented with the guidelines of this standard, MULTIPLE GENERATORS AND
RECEIVERS may be attached to a common interconnecting cable.

No, ist definately for multimaster and its half duplex and needs only two
lines.
RS-422 is what you describe, which is full duplex and needs 4 lines.

IF NI says, their RS485/422 hardware can do RS-485, then damages must be
covered by warranty.
So lets get thing working
Whats wrong:
NI sometimes write RS-485, but infact means RS-422.
Sample: Measurement and Automation Catalog jan. 2002, page 505 ( Or have
take a look in the contents of the catalog at "Distributed I/O",
"Field-Point".
There is a picture showing connections between a computer- RS-232-
FP-1000-RS-485- 2 FP- modules.
At this place things are wrong, because cabeling is 4- wire and true
RS-485 is 2 wire!
Whats correct:
Othertimes NI knows and also writes the correct pinout of connectors and
cabeling of RS-485:
Sample: NI Serial Device User Manual of my ENET-485/4, Appendix D, Serial
Port Information.
At the chapter RS-485, They write: "Unlike the RS-422 standard, RS-485
adresses the issue of using multiple transmitters on the same line. RS-485
can also withstand multiple drivers driving conflicting signals at the
same time."
Other NI- Serial Port device manuals may contain similar texts.
So here's the solution:
If NI says FP-modules can handle RS-485 and there are only 4 connection
cables for the network connection, then one has to bridge TX+ with RX+ and
TX- with RX-. In this way you just have 2 network wires left. When doing
this, RS- Network devices may handle this situation automaticly, or they
have to be configurated.
For my ENET 485/4, this means:
4-wire RS-422: Serial Port config: Tranceiver mode = 4 wire
2-wire RS-485: Serial Port config: Tranceiver mode = 2 wire TxRdy Auto
So how should involved RS-485 devices behave:
By default, RS-485 all active devices of a network are in Read- mode, so
there are no conflicts. If one device wants to write to the bus, ist
switches its tranceiver to write mode, writes the data to the bus and goes
back to read mode again. The tranceiver switching time from read to write,
or back from write to read, should take 400 �seconds each. People working
with labview have to insert 1ms delay if they want ro read data from the
serial port, after writing.
See National Semiconductor application notes:
http://www.national.com/pf/DS/DS36C278.html#Application Notes
Some timing info, look AN-702 at
http://www.national.com/appinfo/interface/0,1801,121,00.html
My National Instruments ENET-485/4 (Ethernet to 4-port RS-232/422/485)
needs 20ms (= 50 X 400�s) though. The Ni- Support couldn't help me in this
case yet. I don't know how NI-PCI-Serial Port cards behave, but I used a
dozen of RS-232/485 Converter of Adlinks NuDAM series: ND-6520.
http://www.adlink.com.tw/products/RemoteData/ND-6520102130.htm
They work perfect, connected right to the PCs- serial port. They can
handle RS-485 and 422.
In the future, if NI can't get my ENET-485/4 do work with correct timing,
I'll try MOXA http://www.moxapartner.com/ .
Well, this was lots of technical RS-xxx info.

Can i connect the NI 9401 to the 9162 carrier

Hello, can I connect the NI 9401 to the USb-9162 carrier, instead of having to buy the cDAQ-9172 for just one Module ?
ciao, grazie
M. Petrolekas

The NI 9401 is currently not supported for the USB-9162. I don't know what application you have in mind but you also might want to consider some of NI's other USB devices such as the USB-6212/6, USB-6501, or any of the USB-622x or USB-625x devices.

Can't connect or install skype on server 2008R2

Ok, so I have this problem.
No one can use skype on server. Whe you try to sign in, after some time of trying, skype says can't connect. But it was working sometime ago. First, I thought it was the problem with old version. So tryed to upgrade it to version 7.0.0.102 - i couldn't do that. Skype just craches or says it can't connect to server, try to download it manually. When i do that - nothing happens. The error when skype craches is below:
Faulting application name: SkypeSetup.exe, version: 7.1.0.105, time stamp: 0x54c263f3
Faulting module name: dhcpcsvc.DLL, version: 6.1.7600.16385, time stamp: 0x4a5bd9b5
Exception code: 0xc0000005
Fault offset: 0x00001b2d
Faulting process id: 0x57a0
Faulting application start time: 0x01d03c5d3def6fa0
Faulting application path: E:\Users\*****\Downloads\SkypeSetup.exe
Faulting module path: C:\Windows\system32\dhcpcsvc.DLL
Report Id: 8081c41b-a850-11e4-8a66-00155d03e65d
So, i downloaded full version of skype, installed it. Tryed to sign in - same thing, can't connect.
Firewall is ok. Tryed to delete it as mentions in some posts in here. Also, on server, that is identical to this, skype works fine.
Any thought how i can fix this issue?

Please, run the DirectX diagnostics tool (32-bit mode).
Go to Windows Start and in the Run box type dxdiag.exe and press the OK button. This will start the DirectX diagnostics program. Run this diagnostics and save the results to a file. Please, attach this file to your post.
Be aware that you will have to zip this file before attaching it here.

10Gig - GBIC module, can we connect?
