Cisco 10005 ESR AC Power Supply Installation
78-12652-01
Product Description
The AC power supply (Figure 1) provides power conversion directly from the
facility AC input power (100 to 240 VAC nominal) to the –48V VDC used
internally by the system. Power is delivered to the power supply by the AC power
cord. The AC power supply is provided with an IEC 320/C20 AC inlet, rated
16A/250V (20A in North America).
Figure 1 AC Power Supply
The Cisco 10005 chassis has two compartments for power supplies. The chassis
can operate with a single power supply; install two power supplies if you need
power redundancy.
