Agreed, sometimes they make you curse and or end up breaking the plastic on the cabinet.
The tab you pry is a tad too tall, in other words it's like as if it's an exact fit so the trick is to raise or lower the cover at the same time prying with your little flat head.

I got in the habit of gently replacing the covers without locking the tab back in.

If it is a Compact ICS - You don't need to remove the cover to get the Trunk Cards out.
That tricky cover - covers the Software and the Amphenol cable connectors - not the Trunk Cards.

And the left card is Lines 1-4.

Ha, good point Jim! My mistake.

I pulled the number off of the card (without my readers) it appeared to be NT7B75GB-03 ... Is there a range of compatible cards, as I seem to be coming across cards with the NT7B75xx-xx designation??

Sent you a PM.

Thanks guys,
I have ordered a replacement card, per customer request, and will
1- power down
2- replace card
3- power up
4- test system
5..... - wait to get paid ; )

thanks for the help !

The NT7B75GD, NT7B75GE and first version NT7B75GF are known to have issues but not all of them....for me directly is was NT7B75GE that caused the CICS to reboot every so often.

If it fixes it you could put the old card in the other slot for safe keeping if needed in an emergency and or if it has non restricted software then they can add more lines.
Pry out the tabs a little with a small driver then pull them out further with your fingers and slide it out evenly.

Funny thing today....as for the cover I curse it now, today I did a site survey for relocate and last tenant left a CICS and Callpilot, all I had were my keys and could not get the bloody cover off for nothing to see the software version so it will have to wait when I relocate and have tools.
