1. Make sure the devices to be connected are turned off.

2. Use CAT 5 or greater crossover cables to connect the devices to the console server, using

an adaptor, if necessary.

3. To connect modems, use straight-through CAT 5 or greater cables, with an appropriate

connector or adaptor (USB, DB-9 or DB-25) for the modem.

NOTE: To comply with EMC requirements, use shielded cables for all port connections.

WARNING: Do not turn on the power on the connected devices until after the console server is turned on.

To daisy chain PDUs to a console server:

This procedure assumes that you have one PDU connected to a serial port on a console server.

NOTE: Daisy chaining is not possible with SPC PDUs. ServerTech PDUs will allow only one level (Master and

Slave) of daisy chaining.

1. Connect one end of a UTP cable with RJ-45 connectors to the OUT port of the connected

PDU.

2. Connect the other end of the cable to the IN port of the chained PDU. Repeat both steps

until you have connected the desired number of PDUs.

NOTE: For performance reasons, Avocent recommends connecting no more than 128 outlets per serial port.

Turning On the Console Server

The console server is supplied with single or dual AC or DC power supplies.

WARNING: Always execute the shutdown command through the web manager, CLI or DSView 3 software under

the Overview/Tools node before turning the console server off, then on again. This will ensure the reset doesn't

occur while the file system in Flash is being accessed, and it helps avoiding Flash memory corruptions.

To turn on a console server with AC power:

1. Make sure the console server is turned off.

2. Plug the power cable into the console server and into a power source.

3. Turn the console server on.

4. Turn on the power switches of the connected devices.

To turn on a console server with DC power:

DC power is connected to DC-powered console servers by way of three wires: Return (RTN),

Ground (GND) and -48 VDC.
