Caution<br />

Step 7<br />

Step 8<br />

In a system with dual power supplies, connect each power supply to a separate input line. In case of<br />

a line failure, the second source will most likely still be available.<br />

Remove the safety flag, lockout devices, or tape from the circuit breaker switch handle, and restore<br />

power by moving the circuit breaker switch handle to the on (|) position.<br />

Verify the power supply operation by ensuring that the power supply front panel LEDs are in the<br />

following states:<br />

• INPUT OK LED is green<br />

• FAN OK LED is green<br />

• OUTPUT FAIL LED is not lit<br />

If the LEDs indicate a power problem, see the “Identifying Startup Problems” section on page E-3.<br />

Removing and Installing the Fan Tray<br />

This section describes how to remove and install fan trays for the <strong>Catalyst</strong> <strong>6500</strong> series switches.<br />

Note<br />

If your <strong>Catalyst</strong> 6506, <strong>Catalyst</strong> 6509, or <strong>Catalyst</strong> 6509-NEB chassis is equipped with a Supervisor<br />

Engine 2 and you using the fan tray removal and replacement procedure to upgrade the chassis from a<br />

fan tray 1 (low-speed) to a fan tray 2 (high-speed), you must first check the chassis configuration using<br />

the hw-module fan-tray version 2 command to check for configuration problems, such as power supply<br />

compatibility and power sufficiency. If the system does not detect any configuration issues, a message<br />

is displayed saying that it is OK to change the fan trays. This command applies to <strong>Catalyst</strong> <strong>6500</strong> series<br />

switches that are configured with a Supervisor Engine 2 only. This command is not required in systems<br />

that are configured with either a Supervisor Engine 720 or a Supervisor Engine 32.<br />

Required Tools<br />

You might need a flat-blade or number 2 Phillips-head screwdriver to loosen or tighten the captive<br />

installation screws on the fan tray.<br />
