Removing and Installing the 8xDMT

The following sections describe how to remove or install an 8xDMT.

Caution Proper ESD protection is required whenever you handle Cisco equipment. Installation and

maintenance personnel should be properly grounded by means of grounding straps to eliminate the

risk of ESD damage to the equipment. Equipment is subject to ESD damage whenever it is removed

from the chassis.

Note All cards must be fully seated in the chassis. Push on the faceplate of each card to be sure that the card

is fully seated.

Removing an 8xDMT

Complete the following steps to remove an 8xDMT from the chassis:

Step 1 Connect a grounding strap to the ESD grounding jack on the chassis.

Step 2 Use a flat-head screwdriver to move the locking tab from the locked to the unlocked position. Be sure to

turn the locking tab so that it does not overlap the line card ejector lever as shown in Figure 2.

Step 3 Lift the ejector lever to disconnect the line card from the backplane.

Step 4 Carefully slide the line card out of the slot.

Either replace the line card that you remove, or insert a blank faceplate in the empty slot. See the

“Installing an 8xDMT” section on page 13 for 8xDMT installation instructions. See the “Installing a

Blank Faceplate” section on page 14 for blank faceplate installation instructions.

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to

hazardous voltages and currents inside the chassis; they containelectromagnetic interference(EMI)

that might disrupt other equipment; and theydirect the flow of coolingair through the chassis. Do not

operate the system unless all cards, faceplates, front covers, and rear covers are in place.
