Installation
Module Installation Precautions
Please read and follow the precautions listed below before installing the
front and rear modules and any fiber optic option submodules:
• Use standard anti-static procedures during installation. As modules
can be installed or removed when the GeckoFlex frame is powered up,
before removing the cover, please use an anti-static bracelet tied to a
metal part of the frame.
• Install the rear module first, the 8900GEN-SM submodule on the front
module (if used), the front module, then the optical submodule option
(if used).
• When installing or removing a rear module, loosen or tighten the
screws holding the retainer clips to the frame manually with the
retainer clip tool provided inside the front cover of the frame or use a
2 mm (5/64”) hex screwdriver. Please do not use an electric screw-
driver.
Note On newer 751- version GeckoFlex frames, a Rear Retainer Clip removal tool
and 2 extra retainer clips and screws for installing them are provided on the
inside of the frame cover.
• Make every effort to leave the screws holding the retainer clips in place
(do not remove them completely). They are very small and can easily
drop into other equipment causing a shorting hazard. (Two turns of the
screw should be enough to loosen the screws, 3 turns or more will
remove it.)
• When installing a rear module, tighten the screws on the retainer clips
just until snug. Do not apply more force than is necessary to seat the
rear module. The retainer clip screw torque specification is given in the
Mechanical
specifications in Table 9 on page 99 .
• If using a fiber optic submodule, handle it carefully, use anti-static pre-
cautions, and read the
Fiber Optic Cleaning Requirement on page 19
before cabling.
