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.

b.
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

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.
