Upgrading the System
Replacing Modules
10-17
CAUTION:
Do not force the module. Use the carrier shelf as a reference and do not tilt, slant or
rotate the module. If the module does not insert easily, remove it, clear any obstruction,
and reinsert it.
9. Connect the line and extension cords one at a time, making sure to place the correct cords
into their corresponding jacks on the new module. (See “Connecting Lines and Extensions” on
page 2-16.)
10. Reconnect the power cord.
CAUTION:
The power cord should hang straight down from the connector, flush against the plastic
case. Do not install the power cord at an angle to the case or with a loop in it.
11. Move the carrier’s On/Off switch to the “On” position (“—”).
12. Check that all green lights on the fronts of the modules are lit:
■ If a single light is out, power down the control unit, reseat the module, and power up the
control unit.
■ If multiple lights are out, power down the control unit, reseat the leftmost module that has
a light out, and power up the control unit.
■ If the lights are still out, call for support as instructed on the inside front cover of this guide.
13. Make sure all modules are seated properly.
14. If you have Release 4.0 or later:
a. Position the carrier cover over the modules so that the openings on the top of the carrier
cover align correctly with the tabs at the top of the installed 5-slot carrier and modules.
b. Rotate the carrier cover into position so that it aligns correctly with the thumb screw
opening on the bottom of the carrier.
c. Tighten the thumb screw. To ensure proper alignment and safe operation, tighten the
thumb screw securely.
If you have Release 3.0 or earlier:
a. Replace the cover by grasping it by its upper edges and holding it squarely over the
control unit (see Figure 10-14). Place the cover over the modules and make sure it fits
firmly in place.
