Proliant 5500 not booting\posting flashing Attention LED

[bradoholic]

I came in last night to remove the troublesome DLT drive from a Proliant 5500 server, troubleshoot and hopefully fix the problem, and returned the server to its former state.

I brought down the server, removed the DLT, as I predicted the Leader had come loose within the DLT drive so I re-threaded it, re-assembled the server, but on powering up the server wouldn't start.

Symptoms

-When you plug in the power cable to the rear of the server you get a green light to indicate power.

-When you press the 'On' switch at the front of the server the attention LED flashers green 10 times, then once orange (Attention LED is located at the rear of the server and is represented by a circle with an exclamation mark in it). Nothing else really happens although if you look closely at the LED's on the front of the box they very faintly come on for a nanosecond.

I have pulled the server apart checked all of the cabling, tried varies combinations of removing the DLT, removing the SCSI controller, reseated all of the cards and cables (Including Memory, Processors, Fans, Disk Cage)

I have called Compaq who informed me that we don't have a support contract, but have been considering to fork out the £560 an hour for support.

I have searched the internet for related doc's which informed me to reseat all of the components.

Take ti down to minimum config , 1 proc, 1 bank of memory,remove all cards, 1 power supply. swap in\out 1 thing at a time. Try clearing the cmos. Do you have any interlocks open?

I had the same problem with a proliant 3000 I received from work when they were going to throw it out. I was trying to test it after I pulled out some of the cards that I wouln't be using. I left the covers off to test. The case covers need to be in place bacause they depress some buttons that will allow the server to boot. Make sure all the case covers are on correctly and that they make contact with the buttons. After I did this the server came right up. It seems like the blinking light on the power supply is a timer testing whether the case covers are there and then tries to boot again. The green light counting to 10 then the 1 orange light for a failed boot and then restarts the timer. I am not a hardware guy at all, infact I work on the software side so if I named anything incorrectly or used the wrong terminology I am sorry. I thought that this exprience might help some others who may have some trouble getting started like me.

Thanks

The problem is related to loose connections or with the cover sensor. So kindly check for any sort of loose connection. If side covers are open then close them first because some servers have got cover sensors.

You might also want to check these cover switches themselves.

They tend to fall inward a bit after fair use (a.k.a. when removing the side/top covers a lot )
And thus not making contact even when the covers are in place..
