10.3 USING THE MODULE REMOVAL TOOL
A module removal tool is provided with each RFL 9660 to simplify removal and replacement of rear-panel I/O
modules. The tool is stored next to the PWR/ALARM I/O module.
To use the module removal tool to remove and replace an I/O module, proceed as follows:
1.
Disconnect all wiring from the I/O module to be removed.
Tag all wires before removal. This will simplify rewiring once the I/O module is replaced.
2.
Pull the module removal tool out of its storage space.
3.
One end of the module removal tool is threaded. Insert this end into the threaded hole on the I/O
module to be removed, and turn the tool clockwise until tight.
4.
The PWR/ALARM I/O and communication I/O modules (VF 2W, VF 4W, or DTE I/O) are held in place
by quarter-turn fasteners. If removing one of these I/O modules, use a flat blade screwdriver to turn
each fastener one quarter-turn, until it is loose.
The MSM I/O and FIBER OPTIC MASTER I/O modules are held in place by two flat head slotted
screws (one on each end). If removing one of these I/O modules, use a flat blade screwdriver to
remove these screws.
5.
Using the module removal tool as a handle, pull the I/O module out of the chassis.
6.
Disconnect the module removal tool from the I/O module.
To replace an I/O module, proceed as follows:
1.
Push the I/O module into the chassis until its edge connector engages its mating connector on the
chassis motherboard.
2.
If a PWR/ALARM I/O or communication I/O module (VF 2W, VF 4W, or DTE I/O) is being replaced,
use a flat blade screwdriver to push in and turn each fastener one quarter-turn, until it is tight.
If an MSM I/O or FIBER OPTIC MASTER I/O module is being replaced, use a flat blade screwdriver to
install and tighten one screw at each end.
3.
Insert the threaded end of the module removal tool into its storage space, and push the tool in until is
its firmly seated.
4.
Reconnect all wiring to the I/O module.
Use the tags placed on the wires during removal as a reference.
