The HF-1 enclosures provide one FOM II modem slot for standalone installations. These enclosures are lightweight with rubber feet and may be installed in a variety of locations. For rack mount installations the HF-2SS chassis provides one or two FOM II modem slots. This 1U high space-saving chassis fits into standard 19” racks.

Each modem installed into the HF-1 or HF-2SS requires a power adapter for converting VAC to VDC. Model PSAC08 converts 110VAC to 12VDC with the USA style plug. Model PSAC09 converts 220VAC to 12VDC with the European style plug. Model PSAC15 is also a regulated power supply but is only used with the F2238A or F2245A modems for converting 110VAC to 12VDC.

The HF-20A chassis provides space for up to 20 FOM II modems and fits in a standard 19” rack. The chassis is powered by the AC300WR redundant power supply. The AC300WR is a 1U high rack-mountable unit and is designed to be installed above the HF-20 Chassis. The AC300WR also provides for system alarm monitoring.

Located on the front panel of each modem are two fasteners for securing the unit in place. Also on the front panel are LED indicators for power and link status as provided on each fiber optic modem. Copper, fiber, and power interfaces are all accessible from the rear of each modem. Single or double slot blank panels are offered to protect empty slot positions not in use. Model ADPHF01 and ADPHF02 protect 1 and 2 slots, respectively.
