Chapter 3 Summary of Power and Cooling System Features

Power Protection Component

•It provides power to the Cisco ICS 7750 and Catalyst switches during power disturbances.

•When connected to a serial port on the SAP card, the UPS can be monitored for alarms.

•Using the inline power feature, Catalyst switches that are protected by a UPS provide power to the IP Phones, which are then unaffected by power disturbances.

A UPS has battery power that keeps equipment running for a certain period of time. Up to five battery packs can be added to a UPS for additional power. Also, the UPS can be configured to handle Simple Network Management Protocol (SNMP) management, remote monitoring, and alarm reporting.

The UPS can handle a maximum load of up to 1400 VA (1050W) for all equipment that is connected to it. For information on the APC Smart-UPS, refer to the user manual that comes with the APC UPS.

Cisco RPS 300

The Cisco RPS 300 provides a fully redundant power source connection for up to six Catalyst switches (see Chapter 7, “Features of LAN-Based Switching Technologies,” for additional information about compatible switches). When a power failure occurs in one of the switches, the RPS 300 automatically supplies power to the switch. The RPS 300 can power only one switch at a time. For complete redundancy, you should connect each switch in the Cisco ICS 7750 to a separate RPS 300.

The RPS 300 has one AC input power connector and six DC power output connectors. Figure 3-3 shows the back panel of the Cisco RPS 300.
