LAN Ports
The Switch is equipped with twenty-four auto-sensing RJ-45 LAN ports. These RJ-45 ports support network
speeds of either 10Mbps, 100Mbps or 1000Mbps, and can operate in half and full-duplex modes. Auto-sensing
technology enables each port to automatically detect the speed of the device connected to it (10Mbps, 100Mbps
or 1000Mbps), and adjust its speed and duplex accordingly.
The Switch’s RJ-45 ports also support the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC
power to be supplied to attached devices using wires in the connecting twisted-pair cable. Any 802.3af-
compliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without
requiring its own separate power source. This capability gives network administrators centralized power control
for devices such as IP phones and wireless access points, which translates into greater network availability. For
each attached 802.3af-compliant device, the Switch automatically senses the load and dynamically supplies the
required power. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable.
Each port can provide up to 15.4 W of power at the standard -48 VDC voltage.To connect a device to a port, you
will need to use Category 5 (or better) network cable.
The Gigabit Expansion Ports
The Switch is equipped with two miniGBIC ports that have shared Gigabit Ethernet ports (12 and 24) which
provide for the installation of one expansion module. These ports provide links to high-speed network segments
or individual workstations at speeds of up to 1000Mbps (Gigabit Ethernet). To establish a Gigabit Ethernet
connection using a mini-GBIC port, you will need to install an MGBT1, MGBSX2, or MGBLH1 Gigabit expansion
