3.2 Installing the 6-Slot Rackmount Chassis
Install the chassis first before installing any modules into a 6-Slot
Rackmount/Desktop Chassis. When installing the chassis, observe the
following precautions to prevent electrical or mechanical damage:
1. Protect the chassis from exposure to sunlight and electrical or magnetic
fields.
2. Make sure that the equipment rack remains stable, even with the addition
of the chassis and its associated cabling.
To install a 6-Slot Rackmount/Desktop Chassis:
1. Have four #10 screws and four clip nuts available (hardware may vary
depending on rack type). The rest of the hardware is supplied with the unit.
2. Locate a suitable location in the rack for installation and secure the clip-
nuts onto the mounting rails. Use screws to attach the chassis to the rack.
3. Plug the chassis into a reliable, filtered power source.
4. Elevated Operating Ambient - If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may
be greater than room ambient. Install the equipment in an environment that
is compatible with the maximum ambient temperature (Tma) specified by
Black Box.
5. Reduced Air Flow - Install the equipment in a rack so that the amount of air
flow required for safe operation of the equipment is not compromised.
6. Mechanical Loading - Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
7. 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.
8. Reliable Grounding - Maintain reliable grounding of rackmounted
equipment. Give particular attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).
9. All AC and DC versions are intended for use in a Restricted Access
Location (RAL).

3. A suitable listed circuit breaker shall be provided in the building
installation as the unit's disconnect device. The branch circuit rating (i.e.
minimum 15A listed circuit breaker, etc.).
DC Power Supply Module Wiring Instructions
The following diagram shows the wiring configuration for a -48 VDC power
supply module for the 20-Slot Rackmount Chassis 2DC and ACDC.
NOTE
The chassis is protected against incorrect wiring configurations. When wired
incorrectly, the chassis will not function, but no damage will occur.
3.1.2 Installing SNMP Management and Application Modules
To install a module:
1. Remove the blank bracket (if present) covering the slot where the module
will be installed. Black Box recommends installing blank brackets in
unused module slots.
2. Slide the module into the chassis using the card guides.
3. Secure the module to the chassis by tightening the captive screw. (Refer to
the documentation shipped with the module for configuration information.)
4. When installing modules, observe ESD precautions (refer to Chapter 7,
Electrostatic Discharge Precautions).
To manage a 20-Slot Rackmount Chassis, install the SNMP Management
Module in the appropriate slot of the chassis.
• Install the 20-Slot Rackmount Chassis SNMP Management Module into the
first slot of the chassis.
NOTE
This slot is ONLY for the Management Module; do not install Application Modules such
as media conversion and mode conversion modules in this slot.
