Using the RJ-45 Connectors
Figure 24 Connecting an RJ-45
To connect:
Push the RJ-45 plug into the
RJ-45 jack until the tab on the plug
clicks into place. When power is
on for the switch and for the
connected device, the port LED
should come on half-bright to
indicate link is established. If the
port LED does not come on when
the network cable is connected,
see “ Diagnosing with the LEDs”
(page 69), in chapter 5,
“Troubleshooting”. To disconnect:
Press the small tab on the plug
and pull the plug out of the jack
Connecting Cables to Transceivers
If you have any transceivers installed in the switch, the type of network connections you will need
to use depends on the type of transceivers installed.
For transceiver ports, and in general for all the switch ports, a network cable from an active
network device is connected to the port. If the port LED does not come on half-bright when the
network cable is connected to the port, see “ Diagnosing with the LEDs” (page 69) in chapter 5,
“Troubleshooting”.
(Optional) Insert transceivers.
Stacking Information and Topologies
The 3810M switches support the FlexChassis Mesh feature for stacking the switches. When
3810M Stacking Modules (JL084A) are installed in the switches, any combination of up to ten
3810M switches can be stacked together via high-speed backplane cables to form a single
