Removing the Power Supply Module

Removing the Power Supply Module

The power supply modules are hot-swappable. By removing the power supply modules, you can power off the switch without disconnect the wiring from the power-input terminal.

Step 1 We recommend that power be OFF at the AC or DC circuits. Locate the circuit breakers, turn them OFF and tape them in the OFF position.

Note If the power is not off at the AC or DC circuit breaker, do not touch the power-input terminal.

Step 2 Verify that the PSU LED and PSU OK LED is blinking red or is off.

Step 3 Use a Phillips screwdriver to loosen the captive screws that secure the power supply module to the switch (see Figure 3-15).

Step 4 Remove the power supply module from the power slot. The power supply module might be hot (see Figure 3-16).

Step 5 Install a new power supply module or a blank cover.
