The Interconnect Cable

The Interconnect Cable is used to interconnect two Switch units, both fitted with Interconnect Modules.
The standard Interconnect Cable is 1 m (3.28 ft) long and color-coded with a yellow marker at one end and a blue marker at the other end.
The end of the Interconnect Cable that you connect to the Switch determines the identity of the Switch. The Switch that has the blue end of the cable connected to it will be Unit 1. The Switch that has the yellow end of the cable connected to it will be Unit 2.
The terms Unit 1 and Unit 2 are used simply to identify the Switch units for management purposes only.

you are ready to install it into a Switch.
Do not touch any of the pins, connections or
components on the Module.
Handle the Module only by its edges and front panel.Always store or transport the Module in anti-static
packaging.

Installing the Module into a Switch

To install the Module:
1 Ensure that the power supply and the backbone
connection cables are disconnected from the Switch. Always wear an anti-static wristband connected to a suitable earth point.
2 Undo the three screws securing the blanking plate at the
rear of the Switch using a suitable screwdriver. Do not remove any other screws from the rear of the Switch.
3 Remove the blanking plate. 4 Hold the Module so that the text on the front panel is
upright and insert it into the Switch, ensuring the connectors are fully engaged (see Figure 2). Make sure the Module is pushed fully in.
5 Secure the Module by tightening the three captive screws
