Video Processor Door Removal Clearance
CAUTION The Video Processor front door must remain in place and closed during
normal system operation to maintain maximum cooling efficiency.
The K-Frame Video Processor door can be completely removed when
installed in a rack immediately below conventional flush mounted rack-ear
only equipment. If the K-Frame power supply is mounted directly above
the K-Frame chassis, the chassis door can be completely removed after
removing the power supply’s front screen. However, mounting a K-Frame
in a rack immediately below other equipment that extends forward from
the rack (for example, under another K-Frame chassis) may not provide
enough clearance to remove the K-Frame door.
If mounted below equipment that extends forward from the rack, allow at
least 24 mm (0.94 in.) of vertical clearance above the K-Frame to permit
door removal. A flush design 1 RU blank filler panel can be used for clear-
ance, if required.
