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.
