Cabling and Powering On the Switch
Perform the following procedure to connect the data cables to the
switch ports and to apply power to the switch.
1. If your AT-8000 Series Switch has twisted pair ports, connect the
twisted pair data cables to the RJ-45 ports on the switch, as shown in
Figure 34.
Figure 34 Connecting the Twisted Pair Data Cables
When connecting a twisted pair cable to a port, observe the
following guidelines:
# An RJ-45 connector should fit snugly into the port on the switch.
The tab on the connector should lock the connector into place.
# Since the ports on the switch are auto-MDI/MDI-X, you can use
either straight-through or crossover twisted pair cables to
connect any type of network device to a port on the switch.
# If your network topology will contain a loop where two or more
network devices can communicate with each other over more
than one data path, do not connect the network cables forming
the loop until after you have activated the Spanning Tree Protocol
(STP) on the switch. Data loops can adversely affect network
performance. For instructions on how to activate STP, refer to the
AT-S39 Management Software User’s Guide.
