Connecting the Switch to the AC-Input Power Supply
Applying Power to the Power Converter
Move the circuit breaker for the AC outlet or the DC control circuit to the
on
position.
The LED on the power converter front panel is green when the unit is operating normally. The LED is
off when the unit is not powered or is not operating normally. After the power is connected, the switch
automatically begins the power-on self-test (POST), a series of tests that verifies that the switch
functions properly. For instructions on how to interpret POST results, see the
.
Connecting the Switch to the AC-Input Power Supply
The Cisco IE 3000 switch can be used with an optional AC-input power supply (PWR-IE50W-AC or
PWR-IE50W-AC-IEC).
These sections describe the steps required to connect the switch to the AC-input power supply:

Attaching the Power Supply to the Switch
To attach the AC-input power supply to the switch, follow these steps:
Step 1
Remove the left side panel of the switch by firmly grasping both sides of it in the middle and pulling it
outward. If necessary, use a screwdriver to open the side panel. See
for a illustration of how
to remove the switch side panel.
Step 2
Push the upper modules latches (at the top of the switch and the AC-input power supply) up and the lower
module latches (at the bottom of the switch and the AC-input power supply) down. See
for
an illustration showing the latches operation.
Step 3
Put the two modules together so that the AC-input power supply fits in the switch recess.
Step 4
Push the upper module latches down and the lower module latches up to secure the AC-input power
supply to the switch.
