26 6800/7000 Series - Frames and Power Supplies Installation and Operation Manual
Installation Requirements
The FR-7001 frame is a 1RU unit that requires 1.75 in. (44 mm) of
standard 19 in. (483 mm) rack space. The depth from the mounting
surface is 11 in. (280 mm).
The FR-7000MB MIX BOX is a 1RU high, 1/3 RU wide single-module
frame. A MMT-03 Mounting Tray holds up to three MIX BOXES for
rack mounting.
LEDs
The CF-6801 and the FR-7000MB are the only mounting frames in this
series that have front panel LEDs. In other frames, LEDs are provided on
the front of the power supply module. The LED on the front panel of the
FR-7000MB MIX BOX indicates that there is power supplied to the unit.
Installation
Before installing your MIX BOX, inspect the equipment for any visible
damage which may have occurred during transit.
To verify the safe arrival of the embedded power supply follow this
procedure:
1. Pull the black locking pins on each end of the FR-6804(-1) front
panel until they snap out of position. These pins remain attached to
the panel.
2. Slide the front panel out and tilt down.
3. The 6804PS power supply is located on the right side of the frame.
Turn the ON/OFF switch to the OFF position.
4. Close the FR-6804(-1) front panel and snap the locking pins back
into position. Power to the CF-6801 is now removed.
5. Check that air is being drawn in through the front panel of the
FR-6804(-1).
