Caution:
When the optical port has not been connected with a fiber connector or its dustproof
cover is open, there might be some invisible radiation emitted from the optical port. So
do not stare into the optical port directly.
Cover the optical port if there is no connector plugged in.
4.7 Cabling
4.7.1 Table-Mounted Switch
If the chassis of a switch stands alone, you do not have to care about the inside or
outside cabinet cabling. All the port service cables can run along the left side of the
chassis (cabling channel), and the chassis power cables can run upward or downward
based on the specific conditions in the equipment room (lightning protection box,
terminal bar etc).
4.7.2 Rack-Mounted Switch
For the switches are mounted in a 19-inch standard rack, the service cables can be
bound to the cable binding rack at the left side of the chassis and be arranged to run on
the cable rack or in the raised floor according to the situation in an exchange equipment
room (whether the signal cable of the room is accessed from the cable rack on the top
of the chassis or the cable channel under the floor.) Collect all the transit data signal
cable connectors and locate them on the floor of the chassis instead of any places
outside the chassis for fear of unexpected damage. The power cables run out of the
rear left of the chassis and either on the cable rack or in the raised floor as near as
possible based on the specific conditions in the equipment room (lightning protection
box, terminal bar etc).
4.8 Cable Binding
4.8.1 Use of Labels
Correctly edit the label and paste it to a proper place on the bound cables.
4.8.2 Precautions for Cable Binding
z
Bind the cables straight in the cabinet. No twisting or bending.
