Removing a Power Module
This section describes how to remove a power module from the Cisco CRS-1 8-slot line card chassis.
For information on the difference between the power types, see the
“DC Power Systems” section on
page 2-4 and the “AC Power Systems” section on page 2-8. For complete information on regulatory
compliance and safety, see Regulatory Compliance and Safety Information for the Cisco CRS-1 Carrier
Routing System.
The power module is located on the front of the chassis, and mates with the PDU that is installed on the
back of the chassis (see the
“Installing a PDU” section on page 2-10 for information). Although there
are differences among the power modules (AC Wye, AC Delta, and DC), they are installed in the same
manner. (
Figure 2-9 shows an AC Wye power rectifier for reference.)
