High mortality of Cisco Linksys power supplies.

Hi experts, we have an high mortality of Cisco Linksys Power supplies used for SPA2102 and WRP400. The duration varies between 8 months to 12 months.
The power supply model is 5V 2A PSM 11 R.
What is the cause in your opinion?
Could be related to electrical ring value configured?
This is our setting according to regional raccomandation:
Regards.

Hello Daniele,
There is no known issue with the power supplies of the SPA2102/WRP400.
Reasons why a power supply is failing can be manifold.
Brownouts, blackouts, environmental reasons.
Your settings are looking ok, around the default values.
And they are lower than what is used in other parts of the world.
Regards,
Daniel

Urgent: Cisco 7507 Power supplies

Hi,Please let me know the difference between these 2 part numbers:
PWR-7507/4X2-DC , $1000 and
PWR/7/2-DC , $6500
both are dual dc power supply option. I am confused that which one i have to order.
Thanks,
Saeed.

Saeed,
This is what Cisco presales had to say. If you need just one power supply, you should get PWR/7-DC which is for $6500. The other option PWR-7507/4*2 should be used only if you are configuring a new 7507 DC bundle. The bundle option probably already covers the difference of $5500.

CISCO 3945 Router - ARE POWER SUPPLIES LOAD BALANCED?

CISCO 3945 Routers - Are the 3945 Router power supplies load balanced by default?
We are trying to determine if our switch/server rack at our remote location has maxed out it's power load requirements. I just need to know if the 3945 power supplies load balance by default or if the redundant power supply is ON but not really providing the router with power and is just there incase the other power supply fails - Thank you.

Thank you for your reply. I had read that the "Cisco 3845 and 3845-NOVPN router accommodates two hot-swappable power supplies and a single power supply meets router requirements. The second power supply provides redundancy, load sharing, and increased router availability. Either power supply can be removed without affecting router operation. Any combination of two power supplies is permitted."
Unfortunately, I couldn't find any specific information for the 3900 series routers that stated it also load balanced power.
Follow-up question: Do you know if the 3800 series routers load share by default? I know it is capable of power load sharing based on the above description but do they load share equally by default? If that's the case for the 3800's then hopefully that's the case for the 3900'S series routers. Which means, we have not maxed out our power requirements in our racks.

Cisco Linksys Routers and Apple Products?

I have to seriously ask if there is simply an incompatibility between Cisco Linksys and Apple products?
I have both the WRT600N and the new E3000. Both are exhibiting the same behavior with my Apple products.
On the wireless connection, I am unable to get a download rate from the Internet, higher then maybe 1.2 - 1.5Mbps. Most of the time it is far lower. I am always using the same site for testing. www.speedtest.net and I always use the same testing server for Dallas, TX.
My ISP is Clear, and when going to www.speedtest.net while using the wired connection on my MacBook Pro, I get a download speed of between 5.5 and 8.2 Mbps.
The upload speed is not changed whether I am using the wired or wireless connection. I also notice the severe difference in speed when I use the Wi-Fi on my iPhone. My 3G connection is faster then the Wi-Fi...
So, is there an advanced config for the wireless that makes it behave better with Apple devices?
I have locked the config so far to 802.11g on the 2.4Ghz transceiver and 802.11n on the 5Ghz receiver. I have also set it not to broadcast the BSSID for either as I live in an apartment complex and I do not want to advertise my network to everyone else. I use WPA personal on the 802.11g network and WPA2 Personal on the 802.11n network.
The settings on the advanced wireless screen in the router config for my E3000 are the defaults.
I have tried nearly everything I can think of. I am now beseeching the help of the community at large in the hopes of gleaning some information that I did not already have. Also I hate the new Cisco Connect app.
On a side note, I was very disappointed to learn that while the WRT600N supported IPv6, the E3000 does not. As a result it seems my wired connection on the MacBook Pro is not performing as well as it did on the WRT600N.
If anyone from Cisco see's this, PLEASE re-add support for IPv6 to your routers. It makes no sense to move backwards now.

Which band you are using to connect the wireless computer...?
Is your other computers are working fine...?
If you are using 5GHz on the router to connect your Mac computer then,make sure the wireless adapter does support 5GHz.
Try the following settings...
Keep the Network Mode as "Mixed".For 2.4GHz...Set the Radio Band to Wide-40MHz and change the Wide channel to 9 and Standard Channel to 11-2.462GHz..For 5GHz...Set the Radio Band to Wide-40MHz and change the Wide channel to159 and Standard Channel to 161-5.805GHz.Click on Advanced Wireless Settings...Change the Beacon Interval to 75,Change the Fragmentation Threshold to 2304,Change the RTS Threshold to 2304 and Click on Save Settings...
Now,power cycle the router and check.

Cisco 6500 Power Supply and related configurations if any?

Hi,
My query is with regards to the best practices deployed for connecting Cisco 6509 switches in the DC, attached is the existing and proposed setups, also would appreciate getting the related switch configs to acheive redundancy and high availability of the switches in the DC network.
Regs,
Mahesh

Hi,
this depends on what power-supplies you have and how loaded your chassis is.
For Example:
When your chassis is loaded with
     1x Sup720
     8x GE-TX Linecard (WS-X6748)
     2x 3kW Power-Supplies (WS-CAC-3000W)
Then you have to run the chassis in Combined-Mode because, even if there is no second Sup, the same power is allocated to the second sup-slot as if there were one installed.
Having 2x 6kW Power-Supplies, then you should run your chassis in Redundancy-Mode and go with your proposed setup.
for combined-mode use:
cat6k(config)# power redundancy-mode combined
for redundancy-mode use:
cat6k(config)# power redundancy-mode redundant
verify with:
cat6k# show power
system power redundancy mode = combined
Hope this helps!
regards,
    Dirk

Cisco 6500 power supply and module (hot-swappable?)

Hi everyone!
We have currently a Cisco 6500 with 2 power supply of 3000w. We want to replace these PS for 2 new ones, which have higher wattage: 6000w.
Can we replace them without needing to turn the 6500 off?. I mean, What happens if we insert a 6000w PS and the switch is working with one 3000w PS?
Is it possible to do this replacement "on hot"?
And second, we also have a ws-x6708-10g-3c module. Can we insert this module "on hot"? Without needing to turn the Catalyst 6500 off?
Thanks a lot! and looking forward to an answer.

Depends on your setup the table should be able to help:

Need help configuring Cisco/Linksys wireless router to extend wi-fi signal to living room

My U-verse wireless gateway is in the back of our house. We live in an old 1920's home with solid wood walls. For our macbooks, we get a pretty decent signal, but my wife's iPad 2 get's poor wi-fi speeds. I bought a Cisco/Linksys WRT160N wireless N broadband router. I have a wired connection in my living room (going to a 4 port switch) then connected to my DVR. I tried hooking up the new router but ended up getting no signal on the iPad. In fact, it caused other issues. I ended up disconnecting it and re-booting my gateway. All came back fine. This wireless router replaces a similar unit that went out in after a power failure, so I know this can be done, but I forget exactly how I confiured the old one. I would like it to "extend" my signal to the living room, but I am also willing to create a new network (different SSID). Do I need to turn of DHCP? Are there any web sites that can assist me in configuring the router? I wish I didn't have to deal with this. The signal from the RG is great when you are in the back room (20+ down). But my wife gets about 3 down on her iPad in the living room. Thanks in advance.

Hi ,
I was doing some research on how this can be done. It does not appear there is an option in the Cisco router to set it up as an access point, but there are several options you can do to extend your network.
The first thing you can do is just set it up as a router behind router setup, and you will just have two separate networks. Make sure the DHCP pool does not conflict with the U-verse's gateway of 192.168.1.x.
The second thing you can do is connect the Ethernet cable to one of the LAN ports on your Cisco router instead of using the internet port. This should make it work like a smart switch.
With both setups, you want to probably change the SSID, network key, and wireless security settings to the same thing for wireless roaming abilities. That way, anyone that configures their wireless connection will be connected to both networks. Just make sure the wireless channels are not the same, and I would suggest having them at least 5 apart.
Hope this helps.

HP Officejet Pro 8500a prints slowly over wireless on Cisco Linksys Smart Wi-Fi Router EA6500

I have the HP Officejet Pro 8500a. I recenrly change my wiress router to the Cisco Linksys Smart Wi-Fi Router EA6500.
Nearly every time I print, the documement remains "pending" for at least several minutes, sometimes as long as 20, until it finally starts printing. Once it starts printing, the document is printed quickly.
It doesn't matter the size of the document and the time it remains "pending." I've done test pages with just the word "test" in a Microsoft Word document, and it will remain in "pending" for well over five minutes.
If I print over the USB cord, there are no delays.
I need help. I can't figure out how to remedy this long delay when printing wirelessly.
On a side note in case this is helpful, the Linksys router does have a priority setting where you can select up to three devices for priority access (faster connection?), which seems to be more for bandwidth-intensive devices. I tried adding both the laptop I'm printing from and the printer to this priority list, but that did not improve the print connection speed.
Advice please! Thank you.

Hi Jim-Gr,
I understand you have an Officejet 8500A that has started printing very slowly after switching routers. I'm sorry to hear this has happened but will certainly do my best to assist you.
I appreciate you advising that you have tried connecting the printer via USB and it does make a huge difference. I'm also assuming your previous router didn't go this slowly either. With the things you have tried, my assumption is that it's a setting in the router that needs to be changed. If you're not sure how to change things in your router you can generally call the router company and they will walk you through it.
First you will want to ask them if there are any firmware updates for your router, if there are have them perform the update. If it is up to date already then have them make sure your router is broadcasting at a frequency of 2.4 GHz as that's the only frequency the printer works with.
Second, you will want to make sure the following ports are open:
UDP: 427, 161, 137, 138
TCP: 9100, 9220, 9500, 137, 139, 427
Once all of this is updated, then I would suggest you power cycle everything (turn off the printer and the PC, pull the power on the router for 30 seconds and then turn the other two back on once lights are back to normal) and try again. This should allow your printing speed to go back to normal
Hope this helps, have a great day!

Hooking up AE through ethernet to cisco/linksys router

Apologies if this is a repeat, tried searching.
I used to connect my AE to a Belkin router using a "uplink" button on the back of the router. Everything worked till the Belkin fried one hot day.
Got a new router - Cisco/Linksys "Etherfast" Cable/DSL router (non wireless) that does not have an "uplink" button like the Belkin did. Thought AE would be smart enough to adapt. Not so apparently.
Simply plugged the AE into the new router just like the old one. I can connect to the routers setup screen wirelessly through the AE but cannot access the internet, which is connected to the router through my cable modem.
If I plug the AE directly into the cable modem I do get the internet.
Tried setting the AE to "bridge" mode with no luck. But not sure if I need to configure the DNS settings. Not sure how to do that.
I've done hard/soft resets.
Do I need a crossover cable? Apple says the AE does not require a crossover.
thanks for any helpful info!

Got a new router - Cisco/Linksys "Etherfast" Cable/DSL router (non wireless) that does not have an "uplink" button like the Belkin did. Thought AE would be smart enough to adapt. Not so apparently.
It is always a good idea to perform a complete power recycle of your networking equipment when changing components.
Please try the following:
o Power-down the Cisco, AirPort Express Base Station (AX), and computer(s); wait at least 10-15 minutes. Note: Power-down order is not critical.
o Power-up the Cisco; wait at least 10-15 minutes.
o Plug-in the AX; wait at least 5-10 minutes.
o Power-up the computer(s).
Simply plugged the AE into the new router just like the old one. I can connect to the routers setup screen wirelessly through the AE but cannot access the internet, which is connected to the router through my cable modem.
By this statement, if you mean a wireless client connected to the AX, can access the Cisco's web-based administration pages, then the AX is (at least) getting the proper Private IP address from the Cisco gateway ... and, if this same wireless client cannot access the Internet, it is usually indicative that it is not getting all the proper IP address information from the Cisco ... specifically the DNS IP address information.
Hopefully, the power recycle will fix this.
Tried setting the AE to "bridge" mode with no luck. But not sure if I need to configure the DNS settings. Not sure how to do that.
Bridge mode would be the correct setting for a router that is downstream of another. In this mode, the AX will allow the Cisco to provide both the NAT & DHCP services for the entire network ... either wired clients connected to the Cisco or wireless clients connected to the AX.
Do I need a crossover cable? Apple says the AE does not require a crossover.
No, as both routers are capable of working with either crossover or straight-through type cabling.

Cisco 3850 Power Stack

Monitoring Power Supplies in Prime Infrastructure 2.1

Hi,
Prime Infrastructure is capable of monitoring the power supplies from Cisco devices? Where can I see this feature on PI 2.1? is there any option to enable this, if it's capable?
Thanks

There are two options :
1. You poll the devices for Power supply and see the report based on it.
2. You can configure your devices for environment traps and the device will send traps to PI which can be used as an alert/Alarm in PI.
Envmon traps in Cisco devices can be configured using snmp-server enable traps envmon command.
This command enables or disables Environmental Monitor (EnvMon) status notifications for supported systems. Cisco enterprise EnvMon notifications are triggered when an environmental threshold is exceeded. If none of the optional keywords are specified, all available environmental notifications are enabled.
When the shutdown keyword is used, a ciscoEnvMonShutdownNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.13.3.1) is sent if the environmental monitor detects a testpoint reaching a critical state and is about to initiate a shutdown.
When the voltage keyword is used, a ciscoEnvMonVoltageNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.13.3.2) is sent if the voltage measured at a given testpoint is outside the normal range for the testpoint (that is, at the warning, critical, or shutdown stage). For access servers, this notification is defined as the caemVoltageNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.61.2.2).
When the temperature keyword is used, a ciscoEnvMonTemperatureNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.13.3.3) is sent if the temperature measured at a given testpoint is outside the normal range for the testpoint (i.e. is at the warning, critical, or shutdown stage). For access servers, this notification is defined as the caemTemperatureNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.61.2.1).
When the fan keyword is used, a ciscoEnvMonFanNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.13.3.4) is sent if any one of the fans in a fan array fails.
When the supply keyword is used, a ciscoEnvMonRedundantSupplyNotification (enterprise MIB OID 1.3.6.1.4.1.9.9.13.2.5) is sent if a redundant power supply fails.
For a complete description of these notifications and additional MIB functions, see the CISCO-ENVMON-MIB.my and CISCO-ACCESS-ENVMON-MIB.my files, available on Cisco.com at http://www.cisco.com/public/mibs/v2/.
Status of the Environmental Monitor can be viewed using the show environment command.
The snmp-server enable traps envmon command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Rack design for two ONS 15454's and two 15540-PWR-AC power supplies...

Looking for advice setting up two ONS boxes with two 15540-PWR-AC power supplies. The manuals/CCO show rack design for just the ONS boxes and a fuse/alarm panel. I have two side by side racks for the gear. Has anyone set up the power supplies for an ONS installation? Any feedback would be great.
thx.

Review the AC/DC Power Solution Data Sheet:
http://www.cisco.com/en/US/products/ps6063/products_data_sheet0900aecd801a002a.html
Per the Data Sheet...
The Medium will power 1x 15454
The Large will power 2x 15454
A few things to note...
1. The Power Solution can possibly power more 454s based on the actual power draw of the nodes.
2. There are only 4 circuit breakers on the Large expansion panel. A & B power for 2 454s.
3. It is recommended 454s have 30A fuses/breakers per power source. This can change based on the actual hardware config.
4. You could possibly use the 15A GMT fuses.
5. You could possibly incorporate an external PDU for additional fuses.

Achieve power supplies

hey have ant of ya guys heard of this company before the reason being i just got too of these given too me brand new and both are 500 watt power supplies
the amps are like this i got it from xoxide's website
DC Output: +3.3V +5V +12V -5V -12V +5Vsb
Max(A): 30A, 50A, 25A, 0.8A, 0.5A, 2.0A
Max Output: 500W
if you know of these and they are good please respond
and if you know where i could read up on em please holla back
thx

well just wanted too update ya'll on this new psu it seems too run great although the second fan in it is a upduct and it is interfering with my cooling setup voltages all seem normal on it nothing too low or tyoo high and they are ver steady voltages too not alot of jumping
fair warning though the cables on this psu are kinda short compared too most although that did help too clear up the mad net of cables i had runnin all over my case
my friends system which has the other one in it is running great he has a 1700 t-bred and a fic au13 nforce2 board and he is solid and stable at 2200mhz 11x200
im so jealous as he has a better case than me that allows better cooling and a water setup
well that's my update for now will keep ya posted in the future
all in all seems like a very nice power supply

Cisco Linksys WE-4200 compatible?

Are either Airport Express or Apple TV compatible with the latest Cisco Linksys router?

Will an Airport Express connect wirelessly? I would like to stream music to the second floor system.
Yes, it will "join a wireless network".
Will it connect via ethernet to stream music to the first floor home theater system?
Yes, if you stream to an AirPort Express. it will "connect using ethernet"
Would there be a time lag between the same music played wirelessly and wired at the same time?
Probably
Will Airport express work on my smal third floor hooking in via ethernet but then acting as a wireless extender?
Yes, if you configure it in Bridge Mode to "create a wireless network" using the same wireless network name, security and password as the "main" wireless network
How about Apple TV instead. Would there be a better chance of connecting wired and wirelessly than with the Airport Express?
Strongly recommend an Etherent connection if you plan to stream any kind of high-definition video material. You will need to remember that the Apple TV only has an HDMI output and optical audio out, so your audio video receiver, or television etc at the Apple TV end will need to have that capability.

UPS and 2 power supplies

Out of curiosity, what happens if only one of the two power supplies is kept on UPS and the power goes out?

What do you think will happen?
The power supply connected directly to the main power will go offline.
The power supply connected to the UPS will stay up (as will your RAID).
Your UPS will start to drain.
Ultimately, if the power stays off long enough, the UPS will be unable to sustain sufficient voltage and the second power supply will go offline, bringing down your RAID.
Is that what you mean?
Note that the XServe RAID can have a fairly significant power draw. You need to make sure your UPS is sized sufficiently for your expected runtime.
