Description
Supports one or two power supplies. The following power supplies are
supported:
PWR-950-AC (950 W AC-input power supply).
PWR-950-DC (950 W DC-input power supply).
PWR-1400-AC (1400 W AC-input power supply).
Installed power supplies can be of different wattage ratings. Installed
power supplies can be both AC-input, both DC-input, or one AC-input
and one DC-input. Power supplies can be configured in either redundant
or combined mode.
All Catalyst 6500 series AC-input power supplies require single-phase
source AC. Source AC can be out of phase between multiple power
supplies or multiple AC-power plugs on the same power supply because
all AC power supply inputs are isolated.
Single power supplies are installed in the lower power supply bay. The
second power supply is installed in the upper power supply bay.
Supervisor Engine 2T requires a 1400 W power supply to operate.
For proper operation of the power supply OUTPUT FAIL LED,
Note
systems with single power supplies must be configured with a
minimum of one fan tray and one supervisor engine. Systems with
dual power supplies must have a minimum configuration of one fan
tray, one supervisor engine, and one additional module. Failure to
meet these minimum configuration requirements can cause a false
power supply output fail signal.
