DMS-100 Family NA100 Trouble Locating and Clearing Procedures Volume 2 of 2 LET0015 and up
Trouble locating and clearing procedures (continued)
Locate the PUPS card. The PUPS card occupies the two top rows at the back
of the drawer.
Fit the two-slot guide over the PUPS card and the line card next to it.
Note: If no line card exists next to the PUPS card, do not use the two-slot
guide.
If you use the two-slot guide, hold it in place with your left hand. With your
right hand, clamp the insertion and withdrawal tool to the front edge of the
PUPS card. Carefully remove the card from the socket (as illustrated in step
11).
Leave the two-slot guide tool in place as a guide for the installation of the
replacement PUPS card.
Place the removed card in an electrostatic discharge (ESD) protective
container.
Make sure that the replacement card has the same PEC and PEC suffix as
the removed card.
