Network Ports
■ 24 or 48 auto-sensing 10/100/1000Base-T ports.
All these ports have the “Auto MDIX” feature, which means you can use
either straight-through or crossover twisted-pair cables to connect any
network devices to the switch.
■ On the 2910al devices there are four dual-personality ports. Use either the
10/100/1000Base-T RJ-45 connector, or install a supported ProCurve mini-
GBIC (SFP) for fiber-optic connections.
The RJ-45 connectors support the “Auto MDIX” feature, which means you
can use either straight-through or crossover twisted-pair cables to
connect any network device to the switch.
Dual-Personality Port Operation. By default, the RJ-45 connectors are
enabled. If a mini-GBIC is installed in a slot, it is enabled and the associ-
ated RJ-45 connector is disabled and cannot be used. If the mini-GBIC is
removed, the associated RJ-45 port is automatically re-enabled.
The RJ-45 connector also supplies PoE+ power until a mini-GBIC is
installed. The PoE+ power is turned off when a mini-GBIC is plugged in.
■ Two expansion slots. These switches provide two slots in the back of the
device that can accept any of the al modules. The module provides port
connectivity for 10 gigabit speed. The module ports provide connectivity
through either copper or fiber optic media.
