Aironet 1252 Boot Error

Hi Guys,
I need a help with an Aironet 1252 which is failing on boot. When power on the access-point shows the error below.
WARNING: A memory error occurred during the system start-up
self-test. The device must be serviced if the error persists.
The following commands can, optionally, be used to initialize
the flash file system and the TFTP file transfer system:
But when this happen, I can start the IOS manually doing flash_init and boot in ROMMON. After do this commands, the access-point starts and works normally.
How can I check and correct the memory and solve this issue? Anyone had an idea?
Thanks

Hi,
Yes, it looks like you will need to have the unit RMAd, if you like you could try the mode button procedure to reload the IOS to the AP and reset the AP to defaults as a last option.

Share FCPX with Blu-ray USB3 LaCie writer boot error

Hi
I've been around the bush and back looking at how to burn a blu-ray movie to a disc from FCPX and a slim Blu-ray LaCie drive. I was able to burn a 5 minute movie from FCPX without any trouble but as soon as I try and burn something larger (like an 11gig movie) 1080 HD I get up in the morning to find an error referring to boot directory or something with a boot in it. Sorry can't be more secific than that. It's costing me everytime it goes wrong.
I logged a job with LaCie and they said any disc is compaitble so i'm wondering whether there is an issue with Final Cut Pro X ? Thank you for any assistance.
Mike

OK, I have FCPX. I burned DVDs etc all fine. I then burn a Blu-ray. Initially I tried to save to hard drive and burn from there but that didn't work. Seeing FCPX can burn directly to optical device (LaCie) I tried that (share menu in FCP) I got a boot error message that I didn't take a note of. Today I tried again after I checked a few things out. I put in my BD-R disc into the device. FCPX says it is "finishing create blu-ray disc: burning Blu-ray"
at 85% it then said Insert Disc, i did this and it is hanging.
I have been able to burn a 5 mintue Blu-ray sucessfully but as soon as I get to a 55 minute movie I have been unsuccessful. Layers are automatic. speed is automatic, it's a brand new mac running OS X 10.8.2 The guy I bought the discs from reccomends Roxio but why should I buy new software when FCPX says it burns.

Boot Error Sequence

IdeaCentre K210 57078894 works fine until I completely shut it down and restart it. I get errors like Boot Error Sequence, PXE-E53 No boot filename received, PXE-M0F. When I go to the BIOS setup it says Primary IDE not detected. Can anyone help fix this problem?

Hi,
You might try removing the hard drive and then put it in an external 3.5" USB enclosure and then test it on a different PC. This type of adapter could also be used to test the hard drive on another PC.

Some boot error

I am getting some boot error at the very end at boot time and it moves to fast for me to catch it.
I did try with read -n1 added to rc.conf but as the error is at the very end so it just jumps past the error.
I had a look in /var/log files but could not really find anything.
Where to find the boot log? Or something else?

You should add read at the end of /etc/rc.local

[Solved]Syslinux "booting... boot error" when booting Windows 7

Hello, I've set up my computer to dual boot windows and arch. Windows is on a separate hard drive and I was able to configure syslinux with a boot menu allowing me to select Windows at startup. For a long time this has worked without any problems whatsoever, but this morning I tried selecting windows and I got what is probably the most vague error message I have ever seen.
"Booting...
Boot Error"
According to this post this problem comes in when the ldsyslinux.sys file cannot be found. Unfortunately I was not able to use his suggested fix
syslinux -U /dev/sdb1
I wasn't aware that there was a -U flag for syslinux and after checking it seems that there isn't one.

Sorry, I actually just fixed it on my own, it turns out my BIOS settings were a bit... weird. For some reason I didn't have my windows drive listed and it tried to boot a USB drive I had plugged into my computer. I just had to fix the drive order and it worked fine. Sorry about starting a fairly useless discussion.

Compaq CQ62-215DX-fan boot error, even after fan replacement

I have a Compaq CQ62-215DX laptop. Everytime on startup I get this boot error "a system fan is not operation correctly" The system then automatically shuts itself down after a few seconds.
I ordered a replacement fan and installed it, however I'm still getting the same issue.
I figure the chances of the newly installed replacement fan being DOA are fairly low, so what should be next step to fixing my problem? Are there any common problems with the replacement of these fans on this particular computer? The laptop is a few months out of warranty so I'm either stuck paying a bunch of money to fix it, or buying a new computer if I can't fix it myself. Help!

It's either a bad fan which I agree is unlikely or a bad fan header on the motherboard which means a new motherboard. Sorry.

Aironet 1252 bridge and 802.11n

Hi,
I have two Cisco Aironet 1252 that I want to configure as a point-2-point bridge. Now I want to know if this configuration supports the 802.11n protocol.
Regards,
Screech

Scott,
I found the following statemen in the release note of IOS 12.4 (25d) (http://www.cisco.com/en/US/docs/wireless/access_point/ios/release/notes/12_4_25d._JArn.html#wp291685)
802.11n HT Rates Apply Only to No Encryption or WPA2/AES Encryption
The 802.11n HT rates apply only to no encryption or WPA2/AES encryption. They do not apply to WEP or WPA encryption. If WEP or TKIP encryption is used, the 1250 series access points and any 802.11n Draft 2.0 clients will not transmit at the HT rates. Legacy rates (802.11a/b/g) will be used for any clients using WEP or TKIP encryption
Given this statement how do I configure AES encryption on the aironets 1252 that are configured in bridge mode as I do not see this option. If possible please provide steps using the web interface.

Screech

Antenna alignmenet on Aironet 1252

Hi,
I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?
note: executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
Regards,
Screech

.Now I am having problem having the devices associated . Is there any other way of testing why the devices are having problem associating to each other. Note in the root bridge I get an event that the root has reached the maximum packet retry send to the non-root bridge.
Any idea.
Tnx,
Screech

Aironet 1252 Antenna quantity

Hi There,
I already have an Aironet 1252 and I am going to increase the coverage.
I would like to buy "AIR-ANT24120" but I dont know if I have to buy 3 of them or only would be enough?

Let me try to answer your questions:)
Did you decide to use lmr600 for longer cables and lmr400 for shorter? I could just use lmr600 for all, I think. Of course, as long as the holes in the wall allow for six lmr600's to fit in.
The cost between the two is huge, so when I was 75' or less, I would use the lmr400, anything else would be the lmr600.
Not familiar with what it takes to crimp on RP-TNC vs. N-type connector. Is N-type easier to crimp on? Or is there another reason?
If you can have the cabler's only have to deal with one type of crimp.... the easier the install and that is why we did that. Sparco arrestors were 'N" type and then we used a small jumper from the top of the NEMA enclosure to the AP which of course was rp-tnc.
I just noticed that omni antenna has SMA connector, but it also says "connector options available". I'll talk to them, hopefully they have an N-connector option. Otherwise, not sure about crimping SMA connector.
They offer other connector types.
Duly noted on the tilt and arrestors. I want to protect the AP. I don't think I'll be using enclosures inside, the AP might just be mounted on the wall. In this case. If my LMR has N-type on both ends. I would have to attach RP-TNC arrestor directly to the AP (I'm using 3500e), then attach a RP-TNC to N-type adapter, and then connect the N-type LMR. Or I might just end up using enclosures as in your example with N-type arrestor.
They have small jumpers so you can go from 'N' type to RP-TNC. We used a NEMA enclosure just so it is more clean. the arrestors actually just screwed into the top of the NEMA enclosure, 3 toward the fron and 3 toward the back and the console and ethernet connection on the bottom.

"NI-488 boot error: OpenMarkedDrivers failed"

The GPIB card was working on wednesday, then Friday it was giving me the error "NI-488 boot error: OpenMarkedDrivers failed". I've tried installing an updated driver but nothing works. I don't know if it is a problem with the software or the GPIB card itself

Hi,
What OS and driver version are you using? When exactly does the error show up?.
I only found one (old) reference to this error.

Serious boot error. very annoying. P6NGM mobo. NVIDIA mcp73 chipset

Serious boot error. very annoying. P6NGM mobo. NVIDIA mcp73 chipset
I have a 80gb Western Digital that i installed xp on using another computer but it still wont boot nor will the cd drive boot even with a 100% original valid windows installation disc.
No matter what I do I always get the stupid "Reboot and Select proper Boot device or insert Boot Media in
selected Boot device and press any key."
At first i thought the motherboard was fried so i sent it back and had it replaced. Put it together, booted it, still the same problems. I have the hard drive set as master drive and it has windows xp installed but it still wont boot from it. please assist
System is:
# Intel Core 2 Duo E6750 Conroe 2.66GHz 4M shared L2 Cache LGA 775 65W Dual-Core Processor
# P6NGM Motherboard (MS-7366)
# 1GB RAM
# Onboard NVIDIA MCP73 Series Chipset
# Western Digital Caviar SE WD800JB 80GB 7200 RPM 8MB Cache IDE Ultra ATA100 Hard Drive
# Windows XP SP1 already installed on the hard drive using another computer
# 400W Power Supply

Take attention to WD jumper config:
Jumperless = Standalone
Jumper master = Master with Slave
Jumper slave = Slave with Master
Leave WD drive alone in the channel and remove jumper from the drive:
Make sure that IDE cable is connected in correct direction, (blue to mainboard and black to HDD in a picture below):

Which Aironet 1252 radio module(s)

I was going to use an Aironet 1252 access point to set up a wireless network and was wondering which radio module (or modules) to get. I have no need for backwards compatibility, so it seems that for best performance I should go with a pure 802.11n network. In order to achieve that goal, is one radio module sufficient? And which band would be best? Or is there any advantage (or disadvantage to getting both the 2.4 GHz radio module (AIR-RM1252G-A-K9) and the 5 GHz one (AIR-RM1252A-A-K9)?
Any and all suggestions or thoughts are greatly appreciated. Oh, and if you need any other information about my setup please feel free to ask.
Thanks,
Paul

fella5 is right. You've just mentioned the need for backward compatibility therefore both A/B/G modules is OK.
Are you going to be using a Wireles LAN Controller (WLC)?
The reason why I'm asking is because the 1252 AP, in order to get both RM to work, you need at least 19.0 watts of power. This can only be achieved using either a enhanced PoE switch (such as the 3560-E/3750-E) or a power injector.
The latest code of the WLC (firmware 5.2) will upgrade the AVR of both the radio modules of the 1250 to be able to operate at 15.4 watts of power. Here's the catch though: The new WLC code will allow the 1252 to operate both radios BUT the power output (or signal strength) is curtailed.
However, do you look the 1140 series AP. This model will operate at 15.4 watts of power, full signal strength but the range is not as far as the 1250.
The 1140 (like it's other brother, 1130) was designed for office use: lots of walls, partitions and corners. The 1250 is designed for industrial use: wide-open space, environmental protection (thus the armoured-tank look-feel-weight).
Hope this helps.

Cisco 2112 WALN Controller unable to detect Aironet 1252

I'm new to this.
Got new Aironet 1252 and trying to hook up to 2112 Controller. There are already two existing WAPs linked to the controller but the new one is not showing up. I need step-by-step instructions how to get it working as I'm not sure where to start
I attached the config of the aironet
Please assist

Hi,
The AP is in Autononous mode.. so it will not work with the WLC till we convert itto LWAPP or CAPWAP... Please download the latest capwap / LWAPP image from the below link for1252 AP ( image = c1250-rcvk9w8-tar.124-21a.JA2.tar )
http://www.cisco.com/cisco/software/release.html?mdfid=281235915&flowid=6779&softwareid=280775090&release=12.4%2821a%29JA2&rellifecycle=&relind=AVAILABLE&reltype=latest
and then get the TFTPd32 on your laptop and install it.. make sure the AP and the laptop ethernet interface are in the same subnet and try pinging the AP bvi inte IP from your LAptop.. if we are able to then..
Point the image on the tftp server by going to the right directory.. then issue the belkow command ..
ap#archive download-sw /force-reload /overwrite tftp:///image.tar
ex
Assuming 10.10.10.1 is ur tftp server.. change accordingly..
ap#archive download-sw /force-reload /overwrite tftp://10.10.10.1/c1250-rcvk9w8-tar.124-21a.JA2.tar
This will reload and come up with LWAPP image and the AP will join the WLC and thne you need to configure on the WLC to get this up based on your requirements...
lemme know if this answered your question..

Surendra

GE60 0NC booting error

Hey guys my GE60 0NC seems te have some kind of issues.
When I boot it and logg in the booting seems to stop at the WiFi connecting.
At that moment I can start a few minor programs but a lot of booting hasnt been finished yet.
To fix this I tried to:
-Systemrepair it to 1 day ago
This seemed to help, I could use it again although it ran a lot slower than normal.
In addition some programs seem to have some error, for instance League of Legends won't boot.
However when I shut it down and rebooted it again I was back to the same booting error.
What could be the problem here?
Thank you very much for your time.
Olav

I've been having the same problem for over a week (MSI GE60 - i5-3210M, 6GB RAM and GT650M; bought a bit over a year ago).
It started with a normal boot, but when I logged into my account I couldn't start any programs for 5-10 minutes. My S-Bar also stopped responding and crashed.
At first I suspected malware/virus, and actually found some shady files that I deleted with Malwarebytes Anti Malware.
The problem was still there though, so I did a system restore (I couldn't go back more than a few days) and that seemed to fix the problem - but after a reboot it was back.
I could find some errors, like the one you linked, in the Event Viewer - but also alot of Information-events from NvStreamSvc (several every sec) which is a part of Nvidia.
So today I uninstalled GeForce-experience (couldn't launch it apparently, got some error) and then installed an older display driver 310.90.
I also reinstalled my S-Bar and now it seems like I run pretty decent. The WiFi-logo has gone back to normal and I can start up programs early after a boot.
You could also try and uninstall some recent Windows Updates - I'm not sure if they're involved, but you could always give it a try.
Hopefully this helps you, or someone else, in some way.
