Broadmore 1750 - Release 4.6 4-9
Chassis Installation and Grounding
AC Power Supply Tray
Rack-mounting the AC Power Supply Tray requires:
clear access to front of rack
user-provided rack mounting hardware (screws)
NOTE: No additional air space is needed above the AC Power Supply
Tray when it is mounted directly below the Broadmore 1750 fan tray, which
has a sloped bottom that does not interfere with air flow. Otherwise, provide
at least 1.75 inch (1 RU) of free air space above the AC Power Supply Tray
to ensure proper ventilation.
Perform the following steps:
1. Unpack and visually inspect the AC Power Supply Tray assembly.
2. For ease of rack installation, you can remove the power supply module(s) from
the tray to make it lighter.
3. Adjust the rack mounting brackets for desired for a 19 or 23 inch rack and for
front/rear mounting configuration. As shipped, the brackets will fit a 19” rack
with front-mount configuration. The brackets can be removed and rotated 90
degrees to fit a 23” rack.
4. Rack mount the tray directly below the Broadmore 1750 using facility-
provided mounting hardware.
5. Replace the power supply module(s) after rack-mounting the tray and tighten
the module’s front panel screws.
6. If the tray came with only one power supply module and a redundant power
supply is to be installed, remove the blank cover on the front of the tray, insert
the second power supply, and tighten the front panel screws.
