Installing Backplanes
7 Remove any blank plate covering the desired slot by loosening the spring-loaded retention
screws using a #1 Phillips screwdriver. Gripping the screws, gently pull the blank plate free
from the frame, using a slight rocking motion if needed. Use caution to avoid damaging con-
nector pins.
Or
If reconfiguring the router, relocate backplanes as needed.
8 Insert the new backplane into the frame being sure to align the printed circuit board with the
stamped guides in the frame. Use gentle pressure at the top of the backplane to ensure the back-
plane connector is fully mated with the motherboard.
Classic SWB backplanes must be installed in specific slots, as follows:
See Figure 2-4 on page 12 .
9 Use a #1 Phillips screwdriver to tighten the two spring-loaded backplane retention screws.
10 To maintain proper airflow for cooling, cover any unused backplane slots with a blank plate.
Installing Machine Control Backplanes
The Machine Control card set requires two backplanes. If you are installing a single Machine Con-
trol card set, the two backplanes may be located in any two adjacent slots associated with the
Machine Control card set. If you are installing two Machine Control card sets (64-port configura-
tion), the two backplanes must be installed in specific slots.
Miranda offers an optional connector breakout panel that can be used to convert up to 64 RJ-45
connectors on the router backplane to 9-pin subminiature D connectors (DE9). This breakout panel
occupies 4RUs and hinges open for easy access and to facilitate cable routing. The DE9 connector
wiring follows SMPTE-defined pin assignment standards. For more information, see
Machine Con-
trol Breakout Panel on page 43.

Or
If reconfiguring the router, relocate backplanes as needed.
2 Insert the new backplane into the frame being sure to align the printed circuit board with the
stamped guides in the frame. Use gentle pressure at the top of the backplane to ensure the back-
plane connector is fully mated with the motherboard.
