1. GENERAL DESCRIPTION
1.01
The HWX Integrated Fan/Power Supply provides AC/DC primary power conversion
and fan cooling for Optiworx HWX products that operate on -48 VDC. It is specifically
designed to provide power to a single HWX Equipment Shelf (HX1281EC or HX2281EC).
The fan/power supply is mounted in the rack directly above the HWX Equipment Shelf,
allowing its fans to draw air up and through the shelf.
There are three HWX Integrated Fan/Power Supply models:
110 VAC, single -48 VDC output (HW-PSFAN-1-110)
110 VAC, dual -48 VDC output (HW-PSFAN-2-110)
220 VAC, single -48 VDC output (HW-PSFAN-1-220)
1.02
The intent of the dual power supply is to provide a backup power supply for the
equipment shelf. The power supplys -48 VDC outputs are compatible with telco standard
A BATT/B BATT DC inputs. Each Integrated Fan/Power Supplys DC output provides
-48 VDC at 300 watts.
Warning
:
The Integrated Fan/Power Supply dual output assembly (HW-PSFAN-2-110)
contains two power supplies. This assembly is designed to provide two power supply
sources for one HWX Equipment Shelf. Do not attempt to connect this power supply
assembly to more than one equipment shelf.
2. PHYSICAL DESCRIPTION
2.01
The HWX Integrated Fan/Power Supply assembly is a 19 rack or cabinet mountable unit,
which measures 17.20 wide by 1.75 high (1 RU) by 22.00 deep (see Figure 1-1). The single
supply version of the assembly weighs approximately 22 pounds, and the dual supply
approximately 25 pounds. It provides -48 VDC power and cooling for the HWX Universal
Equipment Shelf (HX1281EC or HX2281EC) and the associated plug-in modules that are housed
in that shelf.
2.02
Three fans are located across the top of the Integrated Fan/Power Supply assembly
such that when placed above an HWX Equipment Shelf it will draw air cooling air up through
the shelf and exhaust it from the top of the assembly.
