gigabit interface

[JDL_2]

Does anyone know how to uninstall the gigabit card of a NClass 4000 within a standard HP 7m rack? I was told before that I could find docs where the hardware are disected or in an exploded diagram and it tells you in a step by step instruction how to do things like this. I was able to find a thread here but the links have been moved. I am unable to find any other docs related to this. This system is online and is not being used and would like to use the interface card on other production boxes. Thanks.

The links are probably not updated since the itrc change..

ie: remove the 1150

The links should work then.

Later,

Again, Check the above link, select documentation, select networking and I/O documentation, select Gigabit network Ethernet and then the installation guide.

The link given will give you only the home index page for N class

Thanks for the speedy response there Bill. This will definitely come in handy. The thread I was refering to had a link that did not contain the string 1150. I beleive I also found that link that pointed out to nclass specs. It was quite what I was looking for. We've got a number of nclass a while back and everytime there is a CE maintainance on a box, I was never around hence do not know how to open one up. Unfortunately, since this particular system is not in use, the support has been dropped as well. I could try tinkering with it myself but risk destroying something.

Hi Shiju. I saw this also before and I was trying to get to the card first. I got to the rack, opened up the front panel and did see side slide racks. I looked in the back and saw plates riveted outside the card. How do I start from the external?

Sorry there Bill. I meant that the link was not quite what I was looking for. This is regarding my first reply. Thanks again.

This PDF should provide the detail you're after.

http://docs.hp.com/hpux/onlinedocs/hw/rp7400/documentation/customer_part_upgrades.pdf

Scroll down to page 27 of the document. This shows how to in/un install cards.


This can be found through:

http://docs.hp.com/hpux/onlinedocs/hw/rp7400/index.html

Then follow:
The "Documentation" link
The "Parts Upgrade" link.

There is a lot of usefull info here.

Hope this helps.

First deactivate the card and remove the software.

IMPORTANT: If you don't have the Rack stabilizers installed and bolted on the front and back of the unit, do not try this.

I would recommend doing the rest with the machine turned off, although I have heard with the proper firmware, and enough spare cable length, you can do this hot.

- Shutdown the machine and flip the power switch off. Label all your cables and ports on the back of the machine.
- Disconnect the cables, as cable management on the back of N's and L's is pretty much non-existant.
- Remove the front cover and remove the six Torx bolts (three on each side). Note these are larger than the Torx in the next steps.
- Pull out the machine about 2-3 inches.
- On the inside of each black attachment brace, turn the 3 Torx Bolts about 6-8 turns and lift off each of the braces. You should probably screw these Torx back in, as they can catch on the Rack mounting rails.
- At the rear of the Rack, gently guide the machine out the rear of the rack, being careful to keep all cables and plugs clear of the machine. Note: if this N is in the very top 11U of the rack, you will have to remove the door guide which is attached to the upper panel in the rear, otherwise it gets in the way. One other thing, if this was factory racked you will have to remove the Torx bolts from the mounting blocks at the back of the machine. They attach the machine to the vertical rails.
- After the machine is out and has locked into place, you should get a grounding strap and attach it to the machine and your wrist. Static, afterall, is still a major problem with electronics.
- Open up the panel door on whichever side the card you want is installed. They are accessed from the left or right side of the machine.
- If there are panel insert guides (like on the L's) you just have to pull the one under the card and the card will come out. If not, you will have to ease the card out with your hands.
- Once the card is out, you should replace the blanking plate to fill in the void. If you don't have one, then you could just tape a piece of cardboard or one from a PC over the hole. These machines can be pretty sensitive to airflow problems.
- Replace the side door panel and reverse the above steps to get the machine back into the cabinet.

You can also access the memory carriers from the back of the machine (from the top panel). CPU's are accessed from the top panel in the front of the machine.

Thanks for all your input. I think I'll have enough to get the task going. Thanks everybody.
