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.
Running Boot Fast
When the switch powers on, it automatically initiates a boot fast sequence. The boot fast sequence allows the switch to
boot up in less than 60 seconds. To test the switch, follow the steps in these sections:
Powering On the Switch, page 54
Powering On the Switch
To apply power to a switch that is directly connected to a DC power source, locate the circuit breaker on the panel board
that services the DC circuit, and switch the circuit breaker to the ON position.
Verifying Boot Fast
When you power on the switch, it automatically begins a boot fast sequence. The System LED blinks green as the Cisco
IOS software image loads. If the boot fast sequence fails, the System LED turns red.
Note:
Boot fast failures are usually fatal. Call Cisco TAC immediately if your switch does not complete boot fast

.
Note:
You can disable the boot fast and run POST by using the Cisco IOS CLI. See the
Cisco IE 2000 Switch Software
Configuration Guide
and the
Cisco IE 2000 Switch Command Reference
for more information.
Disconnecting Power
To disconnect power after successfully running boot fast, follow these steps:
1.
Turn off power to the switch.
2.
Disconnect the cables.
Installing the Switch
This section describes how to install the switch:
Installing the Switch on a DIN Rail, page 55
Removing the Switch from a DIN Rail, page 56
8.
Connect the other end of the positive wire to the positive terminal on the DC power source, and connect the
other end of the return wire to the return terminal on the DC power source.
9.
Insert the wired power plug into the switch PoE power connector and tighten the two screws to secure the
plug.
