An optional cable guard (JL311A) can be attached to the Aruba 2930F 8G PoE+ 2SFP+ Switch to
provide security for the attached network cables. For instructions on how to install this accessory,
see the included documentation.
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 on page 50.
