2.3 Installing the EM
CAUTION Be sure to turn off power to the MMDS when you install or remove
an EM. This prevents power surges that could damage MMDS
circuits.
Follow these steps to install an EM in the MMDS enclosure:
1. Make sure that station module power is off.
2. Unscrew (one quarter turn) the two captive screws of the access panel, then remove the
panel.
3. Install the EM on the platform board: Carefully fit the female 96-pin DIN connectors (on
the bottom of the EM) onto the corresponding male DIN connectors (on the top of the
platform board). Snap the EM onto the plastic standoffs and make sure that the DIN
connectors are joined firmly.
4. Connect the target cable, if appropriate.
5. Reposition the access panel, securing it with the screws.
NOTE Many EM boards have 64-pin female DIN connectors. Like their 96-
pin counterparts, these smaller connectors also mate with the male
DIN connectors of the platform board. The connector keys ensure
proper alignment.
2.4 Removing the EM
Follow these steps to remove an EM from the MMDS enclosure:
1. Make sure that station module power is off.
2. Unscrew (one quarter turn) the two captive screws of the access panel, then remove the
panel.
3. Disconnect the target cable from the EM target connectors.
4. Unsnap all plastic standoffs from the edges of the EM.
5. Carefully lift the EM straight up, separating it from the platform board.
6. You are ready to install a different EM or to configure the platform board. When you
finish such other actions, reposition the access panel, securing it with the screws.
