Switch Features
The features of the 2910al Switch include:
■ 24 or 48 auto-sensing 10/100/1000Base-T RJ-45 ports with Auto-MDIX.
■ Four dual-personality ports—either the auto sensing 10/100/1000Base-T
RJ-45 or the mini-GBIC can be used for each port.
■ Two slots (optional al module slot) are provided in the back of the device
to support a series of transceivers to provide connectivity to other switch
boxes, to a 10 Gigabit concentrator or to any Ethernet compatible uplink.
■ An auxiliary (USB) port for processing a USB command file.
■ The Switches can be connected to a ProCurve RPS/EPS and receive
redundant power from that unit. If the internal power supply in the switch
fails, the RPS/EPS unit will immediately provide all the power necessary
to keep the switch running.
■ Plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■ IEEE 802.3ab Auto MDIX on all 10/100/1000 twisted-pair ports, meaning
that all connections can be made using straight-through twisted-
pair cables. Cross-over cables are not required, although they will also
work. The pin operation of each port is automatically adjusted for the
attached device: if the switch detects that another switch or hub is
connected to the port, it configures the port as MDI; if the switch detects
that an end-node device is connected to the port, it configures the port as
MDI-X. If both devices use Auto-MDIX, the configuration is randomly
selected.
■ Automatic learning of the network addresses in each switch’s 2048-
address forwarding table, (with configurable address aging value).
■ Automatically negotiated full-duplex operation for the 10/100/1000 RJ-45
ports when connected to other auto-negotiating devices—the mini-GBIC
ports always operate at full duplex.
■ Easy management of the switch through several available interfaces:
• console interface—a full featured, easy to use, VT-100 terminal
interface that is especially good for out-of-band switch management
or for Telnet access to the switch.
• web browser interface—an easy to use built-in graphical interface
that can be accessed from common web browsers.
