Take a screwdriver and completely disassemble it then put it back together. There could be a loose connection or a screw that got jammed in a bad place.

As it were, I came into the office at 4AM to work on it :(. Like you suggest, I took the whole unit apart and noticed multiple points of concern (bent jumper terminals, e.t.c.).

The biggest concern, and the main cause of the problem, was a very very badly seated backplane, specifically the lower port that plugs the mainboard. More interestingly was the fact that the right half of that port had all its pins bent like Humpty-Dumpty sat on the thing and used pliers to twist them for good measure - very very bad.

Anyway, I spent an hour re-aligning them, and not managing to break any. I then replaced the mainboard and voila, the console port was now working! I re-inserted the PRI and MICA cards, and the box is working fine!

It's very strange, really, the amount of harm inflicted on the device.

And also once you've spent the time doing that, if it's still not working you will have enough sense of satisfaction that you gave it a good shot, that throwing it in the garbage won't bug you so much. ;-)

Well, I'm very satisfied I didn't have to spend that much more shipping it back for replacement, needless to say, customs duties.

Thanks for all your help.

Mark.

I hope you can still file a shipping claim.

Hello all.

Just powered up an AS5300, but I'm not getting a console response on neither Minicom nor Hyper Terminal. I have other Cisco devices whose consoles are working fine under both terminals. I've used 3 different roll over cables, but the result remains the same.

The AS5300 appears to be booting normally, from a visual standpoint - the OK LED lights up fine after a few seconds of power-up, the PRI ports and MICA modem cards all seem to power up OK too. Attaching a 100Mbps Ethernet cable lights up fine on both the 10Mbps and 10/100Mbps Ethernet ports, even after power-up, suggesting the Bootstrap, Bootloader and IOS have phased and loaded normally.

I have tested all COM baud rates from as low as 110bps to as high as 115.2Kbps (and everything else in between), just in case that was changed, with no luck! My initial console connection yielded 2 garbage characters; I haven't been able to even get those for all subsequent tries.

I then realised that I could issue commands to the console (was testing a Break and realised the router stopped "visually" booting up), but the terminal didn't provide any feedback. So I decided to "blindly" configure the FastEthernet 0 port and setup an IP address. As luck would have it, I was able to ping the box. I configured the VTY and enable secret password and managed to log into the box. Still no console access!

I then did a 'sh ver' and realised the Quad-PRI card and the 2 MICA modem cards weren't showing up at all, contrary to an earlier verifiable test that was sent to me prior to shipping, that shows they were there. IOS at the time was 12.2-2.XB6. We then tried another IOS, 12.3(12) and got the same result, the main 3 cards aren't showing up (despite the fact that they seem to be getting power - ACT LED on the MICA cards and 120 LED on the PRI card are lighting okay, no telco circuit attached yet).

The box is running 12.0(2)XD1 ED for the Bootstrap and 12.1(20) Bootloader. The 'sh controllers' command only displays the 10Mbps and 10/100Mbps port, not the other cards.

I was thinking the box could have been "hit" around during shipping, but it strikes me as odd that all 3 cards would fail. Also, do you think the problem with the console port is related to the problem with the 3 cards?

I can't seem to configure the speed on the console port. I get the following error:

Router#conf t Enter configuration commands, one per line. End with CNTL/Z. Router(config)#line con 0 Router(config-line)#spee Router(config-line)#speed 9600 Failed to change line 0's speed Router(config-line)#

This is very very strange, I haven't experienced this in all my years with working with this device. Any ideas are very welcome. Thanks.

Mark.
