Power connector
The 2930F 24-port and 48-port switches do not have a power switch; they are powered on when connected to an
active AC power source. The switches automatically adjust to any voltage between 100-127 and 200-240 volts
and either 50 or 60 Hz. There are no voltage range settings required.
The Aruba 2930F 8G PoE+ 2SFP+ Switch (JL258A) does not have a power switch, it is powered on when the
external AC/DC power adapter is connected to the switch and to a power source. The external AC/DC power
adapter supplies 54 volts DC to the switch and automatically adjusts to any AC voltage between 100-240 volts
and either 50 or 60 Hz. No voltage range settings are required. Be sure to release the latch on the DC plug before
removing the adapter power cord. (See

page 37.)
Switch features
The features of the 2930F switches include:
• Combinations of fixed 10/100/1000-T and SFP/SFP+ ports, as described under
Network ports
on page 8.
• Power over Ethernet (PoE+) operation (JL255A, JL256A, JL258A, JL261A, JL262A, JL263A, JL264A, JL557A,
JL558A, JL559A)—The PoE+ switches are IEEE 802.3at standard compliant and provide up to 30W per port
to power IP phones, wireless access points, indoor web cameras, and more. For more information, see the
