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.
