number and type of hardware options installed. This includes the number of boards: M/Es,
I/Os, and Modular I/Os.
GV K-Frame XP Video Processor Door Removal Clearance
The GV K-Frame XP Video Processor door on all Frames can be completely removed when
installed in a rack immediately below conventional flush mounted rack-ear only
equipment. Mounting any GV K-Frame XP in a rack immediately below other equipment
that extends forward from the rack (for example, under another GV K-Frame XP chassis)
may not provide enough clearance to remove the door.
If mounted below equipment that extends forward from the rack, allow at least 24 mm
(0.94 in.) of vertical clearance above the GV K-Frame XP to permit door removal. A flush
design 1 RU blank filler panel can be used for clearance, if required.
Replacing Standard Power Supplies
GV K-Frame XP Video Processors come with three power supplies with the option of a
fourth, located in the front of the chassis. Power supplies are hot swappable in systems
containing three or more power supplies.
3 To remove the power supply.
a Open the front door of the Frame.
b Locate the two button locks on either side of the power supply retainer bracket.
c Pull the lock buttons straight forward simultaneously, then slide the retainer up
until it stops and release the lock buttons.
d While grasping the handle on the front of the power supply, using your thumb
press the release button upward and pull the power supply straight out.
CAUTION: The Video Processor front door must remain in place and
closed during normal system operation to maintain
maximum cooling efficiency.
CAUTION: ESD equipment and procedures should be used when
servicing electronic components.
