3.3 Installing Transceivers—MDS Mercury
(If not already installed)
The modular construction of the Protected Network Station makes it
easy to install transceivers. The only tool required is a Phillips screw-
driver. If the transceivers were not installed at the factory, proceed with
the steps below for installation and to connect the internal cabling. Refer
to Figure 5 during these steps.
NOTE: Before installing a transceiver in the chassis, make sure each
radio is operating properly as a standalone unit, and is
equipped with up-to-date firmware code. The latest revision of
firmware for most GE MDS products is available for down-
load at www.GEmds.com.
1. Make sure the power is off.
2. Remove the top cover of the Protected Network Station by loosen-
ing the two screws at the rear panel.
3. If a backup battery is installed in the chassis, be sure it is discon-
nected from the battery control board.
4. Remove the transceiver mounting plates from the chassis by loosen-
ing the screws that secure them to the chassis.
5. Attach the Radio A mounting plate to the first transceiver using four
screws. Secure the mounting plate and radio to the chassis.
6. Attach the Radio B mounting plate to the second transceiver using
four screws. Secure the mounting plate and radio to the chassis.
7. Connect and secure the data interface, diagnostics and power cables
to the transceivers as shown in Internal Cabling Arrangements on
Page 10.
8. Connect the battery cable to the battery control board, if this option
has been purchased and installed in the chassis. (See Figure 33 on
Page 38.)
9. Re-install the top cover of the Protected Network Station and tighten
the side screws.
This completes the installation of Mercury transceivers in the chassis.
Refer to Section 3.5, External Connections to complete the installation.
