48-PoE+, 2530-8G-PoE+, 2530-24G-PoE+, and 2530-48G-PoE+.
■The 2530-8 and 2530-8-PoE+ switches have 8 auto-sensing 10/100BASE-
TX RJ-45 ports, and two Gigabit dual-personality ports (ports 9 and 10)
■The 2530-24 and 2530-24-PoE+ switches have 24 auto-sensing 10/
100BASE-TX RJ-45 ports, two 10/100/1000BASE-T RJ-45 ports (ports 25
and 26), and two SFP slots for supported HP SFP transceivers (ports 27
and 28)
■The 2530-48 and 2530-48-PoE+ switches have 48 auto-sensing 10/
100BASE-TX RJ-45 ports, two 10/100/1000BASE-T RJ-45 ports (ports 49
and 50), and two SFP slots for supported HP SFP transceivers (ports 51
and 52)
■The 2530-8G and 2530-8G-PoE+ switches have 8 auto-sensing 10/100/
1000BASE-T RJ-45 ports, and two Gigabit dual-personality ports (ports 9
and 10)
■The 2530-24G and 2530-24G-PoE+ switches have 24 auto-sensing 10/100/
1000BASE-T RJ-45 ports, and four SFP slots for supported HP SFP
transceivers (ports 25-28).

1000BASE-T RJ-45 ports, and four Small Form Factor Pluggable (SFP)
slots for supported HP SFP transceivers (ports 49-52)
■Power-over-Ethernet or PoE power - The HP 2530 PoE+ switches
support the IEEE 802.3at standard, which allows IP telephones, wireless
LAN Access Points, and other appliances to receive power as well as data
over existing LAN cabling, without needing to modify the existing
Ethernet infrastructure.
■The HP 2530 PoE+ switches are designed with an internal PoE power
supply capable of providing 370 watts of PoE power (HP 2530 48-port
switches), 190 watts (HP 2530 24-port switches), or 62 watts (HP 2530 8-
port switches). Each switch port can provide up to 30 watts (7.5 watts if
all ports are used) of PoE power to connected devices. For further
information regarding PoE power, 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.
■Dual-personality ports - These ports use either the 10/100/1000BASE-T
RJ-45 connector, or a supported HP SFP transceiver for fiber-optic
connection. By default, the RJ-45 connectors are enabled.

1-4
Introducing the Switch
These switches can be directly connected to computers, printers, and servers
to provide dedicated bandwidth to those devices, and you can build a switched
network infrastructure by connecting the switch to hubs, other switches, or
routers. In addition, these switches can be fully managed by HP SNMP-based
and browser-based network management tools.
Using HP SFPs, these products support optional network connectivity with
the following speeds and technologies:

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.
