2.2.8 Connecting Network Cables
This section describes how to install electrical transceivers on the ports and how to connect
them to the peer device ports using network cables according to the network plan.
Context
Before connecting the network cable, check the following:

Network cables are either crossover or straight-through cables. Currently, Ethernet ports on
most devices can dynamically adapt to both types of cables. For devices that do not support
dynamic adaptation, use the correct cables.
In terms of electromagnetic compatibility, network cables are either ordinary or shielded
cables. Shielded cables are preferred because of their higher electromagnetic compatibility.
Before connecting a cable, ensure that the port is labeled and that the cable is inserted into the
correct port. Otherwise, the port module or the device may be damaged.
Before bundling network cables, use a network cable tester to test cable connectivity. Bind the
network cables to form a rectangle inside the cabinet. Each bundle contains a maximum of 20
network cables. Ensure that the cable ties are tidy and tied in the same direction.
The distance between the power cable, PGND cable, and signal cable must be greater than 30
mm.
Procedure
Step 1 If multiple network cables must be connected, attach temporary labels to each end of each
cable for identification.
Step 2 Remove the dust-proof caps from a board interface and insert the electrical module into the
interface.

The cables in the corner are unbent.
The power cable labels are filled in and attached to the cables as required. All labels are
neat and face the same direction, allowing for easy viewing.
The power cable, ground cable, and signal cable are bound separately. The distance
between them must be greater than 3 cm.
Construction conditions
Ensure that the peer device has been installed in the equipment room and the port to
which the network cable is to be connected has been determined.
Cabling route
The engineering document specifies the cabling route from the cabinet to the peer device
in the equipment room. Ensure that the cable length is calculated based on the cabling
path.
Cable label
Ensure that the cable is labeled before being connected to the devices.
