Rack-Mounting the Device

The device is a 19-inch, 2U-high rack mount chassis that can be mounted in a standard 19-
inch rack. Mounting is done by attaching the device directly to the rack's frame using the
chassis' integral mounting brackets (flanges). These flanges are located on the left and
right sides of the chassis. Each flange provides two holes (44.5 mm between screw-hole
centers) for attachment to the rack.
When installing the chassis in a rack, ensure you implement the following safety
instructions:
•
Elevated Operating Ambient Temperature: If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient temperature. Therefore, consideration should be given to installing
the equipment in an environment compatible with the device's maximum ambient
operating temperature (Tma) of 40°C (104°F).
•
Reduced Air Flow: Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation on the equipment is not compromised.
•
Mechanical Loading: Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
•
Circuit Overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of the circuits might
have on over-current protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
•
Reliable Earthing: Reliable earthing of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections other than
direct connections to the branch circuit (e.g., use of power strips.)
Notes:
•
At least two people are required to mount the device in the 19-inch rack.
•
Optional rear and mid-attachment is also supported. The mounting brackets for these
attachments are not provided by AudioCodes and must be purchased from a third-
party vendor of your choosing.

To install the device in a 19-inch rack:
1. With two people, lift the chassis into the rack from the front of the rack.
2. Hold the chassis for support while the second person positions the chassis so that the
front mounting brackets are flush against the front rack posts and that the holes of the
brackets align with the holes on the posts.
Note: Make sure that the left and right front-mounting brackets are attached at the same
level in the rack posts so that the chassis is supported in a horizontal position.
