Chapter 3 Summary of Power and Cooling System Features
Power Protection Component
Power Protection Component
For complete power protection for the Cisco ICS 7750 system, a UPS is available
for the Cisco ICS 7750 chassis. The Cisco redundant power system (RPS) 300 is
available for the Catalyst switches that are connected to the Cisco ICS 7750.
Uninterruptible Power Supply
A UPS is an external device that maintains power to the system if the power
supply fails. The appropriate UPS for the Cisco ICS 7750 is the APC Smart-UPS,
manufactured by American Power Conversion (APC) Company. The APC
Smart-UPS has the following features:
•
It prevents blackouts, brownouts, sags, and surges from reaching the
Cisco ICS 7750.
•
It filters small utility line fluctuations.
•
When large power disturbances occur, it internally disconnects from the
utility line and supplies power from its internal batteries, returning to the
utility line only when a safe level of power is restored.
