3.2 HP ProCurve 2848 Overview
The HP ProCurve 2848 (Figure 3-3) is a multiport Gigabit switch. Its characteristics include the
following:
• 48 auto-sensing 10/100/1000Base-T RJ-45 ports
• Dual-personality ports — 10/100/1000Base-T RJ-45 ports or mini-GBIC slots for optional
fiber-optic connectivity such as Gigabit-SX, -LX, or -LH
• Plug-and-play networking
• Automatic learning of the network addresses
• Support for the Spanning Tree Protocol to eliminate network loops
• 96 Gb/s backplane with up to 71.4 mpps
• Stacking capability: single IP address management for a virtual stack of up to 16 switches
• Port security to prevent unauthorized access using MAC address lockdown
3.2.1 Front Panel
The HP ProCurve 2848 has 48 auto-sensing 10/100/1000Base-T RJ-45 ports that are spread across
the front panel. To the right are 4 triple-speed copper gigabit ports, and below these are 4
mini-GBIC slots that accept fiber-optic cables. These 8 slots are referred to as dual-personality
ports because you can use either the copper port or the corresponding fiber-optic port. Only four
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.
