3.
Mount the RealPresence Collaboration Server (RMX) 4000 on top of the rack brackets using the
blades or place it on a rack mount shelf with chassis runners.
4.
Fasten the RealPresence Collaboration Server (RMX) 4000 to the rack with eight screws into the
holes provided on the RealPresence Collaboration Server (RMX) 4000 front as shown in figure
above.
Rack mounting screws must be supplied by the rack manufacturer.
Warning:
Ground connection
When the unit is installed on a rack, the rack must be properly grounded to the central
office ground. The rack must be grounded with two-hole compression-type connectors
using copper conductors (tinned or untinned). Wire, bus bar or braided strap
connectors are acceptable.
The procedures of reverse mounting RealPresence Collaboration Server (RMX) 4000 from 23”
brackets to 19” brackets are the same with the procedures described above.
Connect the RMX 4000 to Power Sources
You can connect either an AC or a DC powers according to the power system required at your site.
The following restrictions apply to the conductors and connectors that may be used to ground the unit
when rack mounted:
• When using bare conductors, they must be coated with an appropriate antioxidant compound
before crimp connections are made. Tinned, solder-plated or silver-plated connectors do not have
to be prepared in this manner.
