2 HP ProCurve 2650 An HP ProCurve 2650 is used for multiple roles in an HP Cluster Platform solution. It is used as a system interconnect and it is used to control the console network or the administrative network. This chapter presents the following information relating to the HP ProCurve 2650: • An overview of the HP ProCurve 2650 (Section 2.1) • An explanation of the HP ProCurve 2650 LEDs and buttons (Section 2.2) 2.1 HP ProCurve 2650 Overview The HP ProCurve 2650 has 48 dual-speed ports that are spread across the front panel. To the right is a pair of fixed triple-speed copper gigabit ports, and below these are two mini-GBIC slots that accept fiber-optic cables. These are referred to as dual-personality ports because you can use either the copper port or the corresponding fiber-optic port, however, only two can be in action at any one time. By default, the RJ-45 connectors are enabled. If a mini-GBIC is installed in a slot, it is enabled and the associated RJ-45 connector is disabled. If the mini-GBIC is removed, the associated RJ-45 port is automatically re-enabled. Figure 2-1 HP ProCurve 2650 34 5 12 6 7 The following list corresponds to the callouts shown in Figure 2-1: 1.

2 HP ProCurve 2650
An HP ProCurve 2650 is used for multiple roles in an HP Cluster Platform solution. It is used
as a system interconnect and it is used to control the console network or the administrative
network. This chapter presents the following information relating to the HP ProCurve 2650:
•
An overview of the HP ProCurve 2650 (
Section 2.1
)
•
An explanation of the HP ProCurve 2650 LEDs and buttons (
Section 2.2
)
2.1 HP ProCurve 2650 Overview
The HP ProCurve 2650 has 48 dual-speed ports that are spread across the front panel. To the
right is a pair of fixed triple-speed copper gigabit ports, and below these are two mini-GBIC slots
that accept fiber-optic cables. These are referred to as dual-personality ports because you can
use either the copper port or the corresponding fiber-optic port, however, only two can be in
action at any one time. By default, the RJ-45 connectors are enabled. If a mini-GBIC is installed
in a slot, it is enabled and the associated RJ-45 connector is disabled. If the mini-GBIC is removed,
the associated RJ-45 port is automatically re-enabled.
