Safety Requirements
This section describes the requirements your site must meet for safe
installation and operation of the system.
Site Safety Requirements
For your protection, please read these safety instructions completely
before operating the equipment.
• Look carefully for potential hazards in your work area: moist floors,
ungrounded power cables, frayed power cords, missing safety
grounds and so forth.
• Locate the main circuit breaker within the room.
• Locate the emergency power OFF switch within the room.
• Never assume that power is disconnected from a circuit.
• Use only the power cords supplied with the system.
• Each power cord should only be connected to a power outlet that has
a protective ground contact.
• Ensure that power cords are easily accessible from the back of the
system at all times.
• Place the equipment in a well-ventilated area where the vents are free
from obstruction.
• Do not place heavy objects directly on top of the RMX 4000 unit.
• Do not use liquids around your equipment.
• Keep the area around the RMX 4000 clean and free of clutter.
• Decide on a suitable location for the equipment rack that will hold the
RMX 4000 unit. It should be situated in a clean, dust-free area that is
well ventilated. Avoid areas where heat, electrical noise and
electromagnetic fields are generated. You will also need it placed
near a grounded power outlet.

Polycom RMX 4000 Hardware Guide
1-7
General Installation Precautions
• Use a regulating uninterruptable power supply (UPS) to protect the
RMX 4000 from power surges and voltage spikes, to keep your MCU
operating in case of a power failure. The RMX 4000 requires either
two (DC) or three (AC) power supply cables, each connected to a
power supply.
• Allow the power supply units to cool before touching them.
• When handling electronic components, standard anti-static
precautions must be observed:
—Wear a grounding strap
—Handle cards by their edges only and do not touch their
components or connector pins
—Keep components in anti-static bags, when not installed in the
RMX 4000
Rack Mount Safety Precautions
The following precautions should be followed when installing the
RMX 4000 on a rack:
• The RMX 4000 has a height of 6U. Ensure this space is available on
the rack.
• Ensure that the leveling jacks on the bottom of the rack are fully
extended to the floor with the full weight of the rack resting on them.
• In a single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component
from the rack.
• You should extend only one component at a time - extending two or
more simultaneously may cause the rack to become unstable.
• Before you install the rails, determine the placement of each
component in the rack.
• Install the heaviest components on the bottom of the rack first, and
then work up.
Attention:
The RMX 4000 can weigh up to 40kg when all slots are occupied. Two people are
required to lift the MCU out of the box and also when installing it in a rack.

Chapter 1- Hardware Description
1-8
• Always keep the rack’s trays and card’s slots closed when not
servicing, to maintain proper cooling.
Installing the RMX 4000
The following procedures have to be performed to install the RMX 4000 in
your site:
• Unpacking the RMX 4000
• Installing the RMX in a rack or as a standalone
• Connecting the RMX 4000 to the power source
• Connecting the network (LAN, IP and ISDN) cables to the RMX
Unpacking the RMX 4000
To unpack and lift the RMX 4000:
1When you receive the RMX 4000 packing case, inspect the equipment
for damage and verify that the components match the packing slip.
2The RMX 4000 is shipped in a packing case with Stratocell®
packaging, and the top cover must be unlocked and lifted where the
RMX is placed on the inside of an anti-static plastic bag.
3Open the top cover of the packing case.
Two boxes are placed on the top Stratocell®, labelled:
—Installation Accessories. This kit contains the power cables and a
USB Key.
—Rack Installation Accessories. This kit contains the accessories for
the 19” & 23” racks as follows:

Make sure that boxes contain all the required parts.
4Remove the boxes and top Stratocell®.
5Holding the handle on each side, lift the RMX 4000 from the box, and
place it on a flat surface or install it in a rack. Remove any packaging
material prior to positioning the RMX 4000.
Attention:
Two people are required to lift the MCU out of the box and when installing it in a
rack.

Chapter 1- Hardware Description
1-10
Installing the RMX in a Rack or as a Standalone
Either place the RMX 4000 on a hard, flat surface such as a desktop or
mount it on a 19”/23” rack.
Standalone RMX 4000 Installation
Place the RMX 4000 on a flat surface or desktop. 
The RMX 4000 must rest on the four feet at the base of the MCU and
must be shifted or moved into position using the two handles
attached to the front.
Rack Mount Preparations
• Optional - Depending on the rack installed in your site, you may
need to remove the handles if they are attached to the RMX 4000.
Unscrew the handles from the chassis as shown in Figure 1-1,
“Optional - Fast feet and handle removal”.
• Optional - If the opening in the rack that is allocated to the RMX 4000
is exactly 6U, the feet must be removed from the RMX 4000 to install
it in the rack. Unscrew the feet from the chassis as shown in
Figure 1-1, “Optional - Fast feet and handle removal”.

Placing the RMX 4000 in a 19” Rack
1When the RMX is to be rack mounted chassis runners must be
installed on the rack as shown in Figure 1-2. Two chassis runners are
included in the Rack Installation Accessories kit and are attached facing
inward from the outside of the 19”/23“rack mount.
Figure 1-2 Installing chassis runners and RMX in a rack
2Mount the RMX on top of the rack brackets using the blades or
placing it on a rack mount shelf with runners.

Chapter 1- Hardware Description
1-12
3Fasten the RMX to the rack with 8 screws into the holes provided on
the RMX’s front as shown in Figure 1-3.
Figure 1-3 RMX 4000 Rack Mount
The airflow of the RMX 4000 is from right to left. Be sure that the
areas on the left and right side of the system are clear for proper
ventilation.
Rack mounting screws must be supplied by the rack’s manufacturer.
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.
