Installation Manual 2. Installing the Device
2.4.3 Connecting to LAN
The device provides up to four RJ-45 10/100/1000Base-T (Gigabit) LAN ports and eight RJ-
45 10/100Base-TX (Fast Ethernet) LAN ports for connection to the LAN (e.g., computers,
switches, and IP phones). These ports support half- and full-duplex modes, auto-
negotiation, and straight or crossover cable detection.
The LAN ports also support Power over Ethernet (PoE), complying with the IEEE 802.3af-
2003 standard. The ports can transfer electrical power along with the usual data over a
single cable to connected equipment (e.g., IP phone) capable of receiving PoE. The ports
automatically detect the presence of IEEE 802.3af-compliant devices. The maximum
wattage available per port is 15.4W.
Note: PoE support is a customer ordered feature.
¾ To connect the device to the LAN:
1. Connect one end of a straight-through RJ-45 Cat 5e or Cat 6 cable to the RJ-45 port
labeled GE (for Gigabit Ethernet ports) and/or FE (for Fast Ethernet ports).
Figure 2-12: Connecting the LAN Ports
2. Connect the other end of the cable to the Gigabit Ethernet network (for the GE ports)
and/or Fast Ethernet network (for the FE ports).
