Paradyne CPX-1000 manual Removing, Replacing Cards

1000-A2-GN22-005. Repair Procedures

Removing and	To remove and replace cards:
Replacing Cards
Step 1	Remove the inter-module cables, as necessary.
Step 2	Put on an anti-static wrist strap, and plug the other end of that
	strap into the ESD ground jack in front (or back) of the CPX.
Step 3	Use a Phillips screwdriver to loosen the top and bottom captive
	screws on the front panel of the module.

	Notes
	Replacing cards in the wrong order causes card damage.
	To remove a CP card, remove the CP card first, followed
	by the HSC card. Then insert them in the reverse
	order—HSC first, then the CP.
	To remove MP and line cards, remove the front card
	first, then its corresponding transition card. Insert cards
	in reverse order—transition cards first, then front cards.
Step 4	Flip the card ejectors (Figure 5–4) and wait for the Hot Swap light
	(the blue laser at the bottom of some cards).
