Introducing the Switch
Switch Features
Power Connector
The HP 2530 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 HP 2530 8-port switches do not have a power switch, they are 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 12 volts DC or
54 volts DC (for PoE+ switches) 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.
Switch Features
The features of the HP 2530 Switches include:
■ 8, 24, or 48 auto-sensing 10/100/1000BASE-T RJ-45 ports with Auto-MDIX,
or 8, 24, or 48 auto-sensing 10/100BASE-TX RJ-45 ports with Auto-MDIX.
■ Two dual-personality ports (HP 2530 8-port switches).
■
Two auto-sensing 10/100/1000BASE-T ports and two SFP uplink slots
supporting HP SFP transceivers (HP 2530 24-port and 48-port Fast
Ethernet switches).
■
Four SFP uplink slots supporting HP SFP transceivers (HP 2530 24-port
and 48-port Gigabit Ethernet switches).
■ PoE+ operation—the switches are IEEE 802.3at compliant and provide
up to 30W per port to power IP phones, wireless access points, Web
cameras, and more. For more information, see the
HP Power over
Ethernet (PoE/PoE+) Planning and Implementation Guide , which is on
the HP Web site at www.hp.com/networking/support .
■ The switches support some pre-standard PoE devices. However, the use
of a cross-over cable may be required.
■ Plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■ Auto-MDIX on all twisted-pair ports, meaning that all twisted-pair
connections can be made using straight-through cables. Cross-over cables
are not required, although they will also work.
