Switch - Cisco IE 4000 Hardware Installation Manual

Switch Installation
Connecting to Power
Warning: Installation of the equipment must comply with local and national electrical codes. Statement 1074
2. Use a ratcheting torque flathead screwdriver to tighten the captive screws on the sides of the power connectors.
When you are testing the switch, one power source is sufficient. If you are installing the switch and are using a second
power source, repeat this procedure for the second power connector (DC-B), which installs just below the primary power
connector (DC-A).
When you are installing the switch, secure the wires coming from the power connector so that they cannot be disturbed
by casual contact. For example, use tie wraps to secure the wires to the rack.
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. To test the switch, follow the steps in these
sections:

Powering On the Switch, page 28

Verifying Boot Fast, page 28

Disconnecting Power, page 28
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
successfully.
Note: You can disable the boot fast and run POST by using the Cisco IOS CLI. See the Cisco IE 4000 Switch Software
Configuration Guide 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.
