module in a Netra CT 410 server.
The slot filler panel is secured to the board cage using two screws, one at the top of
the filler panel, the other at the bottom.
3. Get the replacement alarm rear transition module from the shipping kit.
4. Remove the blue protective film from the front of the alarm rear transition
module.
Caution – You must remove the blue protective film from the front of module
before installing it into the server. Failure to do so might keep the metal
springfingers on the side of the module from making contact with the metal panels
on the server.
5. Verify that the ejection levers are unlocked.
You cannot install the module properly if the ejection levers are locked.
6. Keeping the module vertical, slide the module into the slot between the two
guides (
FIGURE 6-20
).
The teeth in the handle of the module must align with the square cutouts in the I/O
slot. When the module is completely seated in the board cage, the two ejection levers
flip inward, and the teeth in the ejection levers fit smoothly in the rectangular
cutouts in the bottom and top plates.

shows how to insert an I/O board
into a slot; the same method applies to an alarm rear transition module.
7. Using a No. 2 Phillips screwdriver, tighten the two captive screws inside the
module’s ejection levers, one on top and one on the bottom.
Tighten the screws to a torque of 0.28 N.m (2.5 in.-lb).
8. Lock the ejection levers on the module.
9. Plug all appropriate cables into the alarm rear transition module.
Tighten the screws on the cable to a torque of 0.23 N.m (2 in.-lb).
