3.1 Mounting
The HU is intended for rack-mount applications. A pair of reversible mounting brackets is
provided that allow the HU to be mounted in either a 19-inch or 23-inch EIA or WECO
equipment rack. When installed, the front panel of the HU is flush with the front of the rack.
Screws are provided for securing the HU to the equipment rack.
3.2 SeRF Card
3.2.1 Network Interface Connection
SeRF front panel has an Ethernet port allowing interface communication with the internal
processor and transfer of data to the optical protocol allowing IP transport between the HU and
the remote(s). The network interface allows the HU to be controlled through a network.
Network interface connection between the HU and the network is supported by a RJ-45 jack 10/
100Base-T (IEEE802.3 compliant) with integrated green ACTIVITY and LINK LEDs. The
Ethernet port supports a maximum cable length of 100 meters (328 feet) to a hub or back-to-
back nodes. CAT5 or better cable should be used when making this connection. The Ethernet
connection should not be connected to an Ethernet circuit used outside the building.
1. The IEEE Specification for Ethernet 100BaseT requires that two twisted pairs be used and that
one pair is connected to pins 1 and 2, and that the second pair is connected to pins 3 and 6.
2. Pinout information is shown in Table 1. See Figure 3 for RJ45 connector wiring
information.
