AC Power Cabling

Either Cisco Systems or the customer can provide the AC power cord. See Table B-12 for the power
cords that Cisco can supply. In addition, you can special-order AC cables with other plugs or
different lengths. If you want to construct the power cord, it must mate with an IEC320 16/20A male
receptacle on the back of the AC power module.

Control and Clock Cabling

This section describes the cables that can connect to the PXM-UI card.

Maintenance and Control Ports

The Maintenance (or Modem) port and the Control (or Console) port connect a node to an ASCII
terminal, workstation, or modem for remote alarm reporting or system monitoring. Refer to Table
B-13 for a description of the cabling and Table B-14 for the pinout of the associated RJ-48 connector.
