RJ-45 Ports
The switch contains 4x 10/100/1000BASE-T RJ-45 ports. All RJ-45 ports support automatic
MDI/MDI-X operation and auto-negotiation, so the optimum data rate and transmission can
be selected automatically.
3.4
SFP/SFP+ Ports
MS400863M provides the Small Form Factor Pluggable (SFP) transceiver slots port 1 to port
24. The SFP slots 21-24 are shared with RJ-45 ports (combo interface RJ-45/SFP). In the
default configuration, if an SFP transceiver (purchased separately) is installed in a slot and
has a valid link on the port, the associated RJ-45 port is disabled. The ports 25 to 28 support
1/10GbE SFP+ transceiver slots. Generally, they are used as high performance backbone
interface, but it is also possible to insert GbE SFP transceivers. Ensure that the configuration
of the port speed matches with the used SFP or SFP+ module.
3.5
LEDs
The switch includes a display panel for system and port indications that simplify installation
and network troubleshooting. The red marked LEDs, which are located on left hand side of
the front panel for easy viewing provides general information about the switch status.
Additional LEDs indicate link and activity status for each port. Details are shown below, and
described in the following tables:
