Introducing the Switch
Front of the Switch
The following image represents the characteristics of the HP 2530 24-port and
48-port Gigabit Ethernet switches.
Network Ports
■ 8, 24, or 48 auto-sensing 10/100BASE-TX or 10/100/1000BASE-T ports.
All these ports have the “Auto-MDIX” feature, which means that you can
use either straight-through or crossover twisted-pair cables to connect
any network devices to the switch.
■ Two dual-personality ports (HP 2530 8-port switches).
■ Two auto-sensing 10/100/1000BASE-T ports and two SFP slots for fiber or
copper uplinks (HP 2530 24-port and 48-port Fast Ethernet switches).
■ Four SFP slots for fiber or copper uplinks (HP 2530 24-port and 48-port
Gigabit Ethernet switches).
LEDs
On the 2530 Switches, there are three groupings of LEDs:
■ switch status LEDs (Table 1-2)
■ port LEDs (Table 1-3)
■ Port LED Mode indicator LEDs (near the selector button) (Table 1-4)
