Catalyst 6504-E Switch
Clock and VTT module
•
One replaceable clock module (CLK-7600=) provides clocking signals
to the EOBC channel and the switching bus.
•
Nonreplaceable voltage termination (VTT) module provides reference
voltage for bus signals.
Fan tray
•
The chassis supports one hot-swappable fan tray. One fan tray model is
available:
–
FAN-MOD-4HS—300 CFM
Note
The fan tray contains eight individual fans. The individual fans are
not field replaceable; you must replace the fan tray in the event of a
fan failure.
•
Fan tray STATUS LED
–
Red—One or more individual fans have failed.
–
Green—Fan tray is operating normally.
Power supplies
•
Supports one or two power supplies. The following power supplies are
supported:
–
PWR-2700-AC/4 (2700 W AC-input power supply).
–
PWR-2700-DC/4 (2700 W DC-input power supply).
•
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.
Note
For proper operation of the power supply OUTPUT FAIL LED,
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.
