Introducing the Switch

Throughout this manual, these switches will be referred to as the 2530-8, 2530-

24, 2530-48, 2530-8G, 2530-24G, 2530-48G, 2530-8-PoE+, 2530-24-PoE+, 2530-

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).

■ The 2530-48G and 2530-48G-PoE+ switches have 48 auto-sensing 10/100/

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.
