Removing and Installing the Cisco 6160 PEM

•

Periodically check the resistance value of the antistatic strap. Ensure that the measurement is between 1

and 10 megohms.

Removing and Installing the Cisco 6160 PEM

The following sections describe how to remove or install a PEM.

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

Caution

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 modules must be fully seated in the chassis. Push on the faceplate of each module to be sure that the

card is fully seated.

Removing a PEM

Complete the following steps to remove a PEM from the chassis:

Caution

If you remove a PEM from the Cisco 6160 chassis in which a secondary PEM is installed and providing

power, the chassis continues to operate. If you remove the only operating PEM from the chassis, power

down the system before you begin.

Step 1

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

Step 2

Power down the Cisco 6160, as necessary.

Use a Phillips-head screwdriver to loosen the two captive screws on the front of the PEM.

Step 3

Grasp the handle on the right side of the PEM and pull the PEM from the slot.

Step 4

Place the PEM in an antistatic bag or in a box lined with antistatic material.

Step 5

See the

Removing and Installing the Cisco 6160 PEM

Place a removed component board-side-up on an antistatic surface or in a static-shielding

container. If you plan to return the component to the factory, immediately place it in a

static-shielding container.

Avoid contact between the printed circuit boards and clothing. The wrist strap protects components

from ESD voltages on the body only; ESD voltages on clothing can still cause damage.

Type the following command to save the configuration changes to NVRAM:

DSLAM# copy running-config startup-config

Set the circuit breaker on the operating PEM to the OFF (0) position.
