Removing and Replacing the Kayak HD Frame Door
WARNING Be very careful when opening the Kayak HD frame door. Take precautions
to avoid electrical shock from components by following the safety precau-
tions described in detail in Warnings
on page 16 and in Cautions on
page 17 . In particular you want to avoid the possibility of electrical shock
by powering down the system and unplugging all equipment before
working on internal components. In addition you should wear a grounding
strap to prevent electrical damage to sensitive electronic components.
CAUTION Operate only with covers and enclosure panels in place — Do not operate
this product when covers or enclosure panels are removed.
You need to take care not to damage the door by following the procedures
described below.
Note A minimum vertical clearance of 7.62 mm (0.3-in.) above the Kayak HD 4 RU
Compact frame door is required to remove the door. When installing the
Kayak HD 4 RU Compact frame in the rack, take care to leave room for
removal of the front door. The front door lifts off vertically and must have suf-
ficient clearance room in order to remove it. If you have equipment mounted
too close to the Kayak HD 4 RU Compact Frame, you may not be able to
remove the door.
