Switch Overview
■
When the FDx (full duplex) indicator LED is on, the port Mode LEDs turn
on for those ports that are operating at full duplex.
■
When the Speed indicator LED is on, the port Mode LEDs turn on for ports
operating at 1000 Mbps. The port Mode LEDs are off for ports operating
at 10 Mbps or 100 Mbps.
Switch Features
The features of the ProCurve Switch 1800-24G include:
■
24 auto-sensing 10/100/1000Base-T RJ-45 ports.
■
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 MDI /MDI-X on all 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 a 10/100 Mbps switch or hub is connected to the
port, it configures the port as MDI; if the switch detects that a 10/100 Mbps
end-node device is connected to the port, it configures the port as MDI-X.
■
automatic learning of the network addresses in each switch’s 8000-
address forwarding table.
■
automatically negotiated full-duplex operation for all 10/100/1000Base-T
RJ-45 ports when connected to other auto-negotiating devices
■
the mini-GBIC ports always operate at full duplex. (1800-24G)
