2.2 Installation Procedure
The Modula Distribution Matrix enclosure can be mounted in a standard
EIA 19 in. (48.26 cm) rack. To hold the enclosure(s) in place, rack
installation ears are attached prior to shipping.
Tools for installation in a rack:
q
Screwdriver
q
Screws that fit your rack [for mounting the enclosure(s)]
q
Link cables (included with multi-enclosure systems, otherwise not
needed)
q
Enclosure(s)
q
Standard EIA 19 in. (48.26 cm) rack [a Modula enclosure is 3 RU
tall and 17 in. (43.18 cm.) deep]
q
Surge protector(s) – highly recommended
To install an enclosure in a rack:
1. Place the enclosure in the rack and attach front-mounting screws to
hold it firmly in place (repeat for each enclosure). You may find it
easiest to install the top enclosure first and move down from there.
2. If you have a multi-enclosure system, link the enclosures. See
Chapter 3, “Linking Enclosures.”
3. Following the Modula Connector and Groupings Guide, attach only
the first two input and output signals to the correct input and output
connectors on the rear of the correct enclosure (see Chapter 4,
“Attaching Inputs and Outputs,” of this guide).
4. Attach power to each enclosure and turn on the entire system (refer
to Chapter 6, “Applying Power and the Startup Sequence”).
WE RECOMMEND USING SURGE PROTECTORS AND/OR AN
AC LINE CONDITIONER
5. Perform a test switch to ensure the system is working properly. See
Chapter 7, “Executing a Test Switch.”
6. When the test switch works correctly, attach all the input and output
cables to the correct input and output connectors on the rear of each
enclosure (refer to the “Modula Connector and Groupings Guide”
and Chapter 4, “Attaching Inputs and Outputs,” of this guide).
If the test does not work correctly, see Chapter 7, “Executing a Test
Switch.”
