•
ESD-preventive wrist strap
•
6-in. long number 1 Phillips screwdriver
•
Torque screwdriver with number 1 Phillips bit and rated accuracy at 5.5 in.-lb (0.62 N-m)
•
AC or DC PM
◦
AC PM (Cisco product number CRS-PM-AC=), or
◦
DC PM (Cisco product number CRS-PM-DC=)
Steps
To install the PM in a power shelf, perform the following steps:
SUMMARY STEPS
1.
Attach the ESD-preventive wrist strap to your wrist and connect its leash to one of the ESD connection
sockets: on the front (PLIM) side of the chassis there is one ESD connection socket right above the fan
controllers. On the rear (MSC) side of the chassis there are two ESD connection sockets right above the
cable management tray in the center of the chassis (left and right). You can also connect the ESD-preventive
wrist strap leash to any bare metal surface on the chassis.
2.
Using two hands to support and guide the PM, slide it into the power shelf. Install PM0 first.
3.
Rotate the ejector lever upwards to seat the PM into the power shelf. Tighten the ejector lever to nominal
install torque of 5.5 in.-lb (0.62 N m), screw the PM into the shelf (see
Figure 33: Securing the PM to the
Shelf, on page 47
). Do not exceed a maximum install torque of 10 in.-lb (1.13 N-m).
4.
Fill the power shelf, in PM ascending order, to the required configuration.
