Chapter 2 Installation 13
Rack-Mount Installation
Before the unit is installed into a rack the following items should be taken into consideration:
• The maximum ambient temperature of this unit is 40°C. Internal temperatures of the rack
assembly should be considered for safe operation.
• Do not block power supply vents or otherwise restrict airflow when installing the unit into the
rack.
• Mechanical loading of the rack should be considered so that the rack remains stable and
unlikely to tip.
• Consideration to the overall loading of the branch circuit should be given before installing any
equipment in a rack environment.
Note: For an add-on system, the system must be mounted in a rack with four toll removable
screws.
Installation Steps Use the following procedure to install the Megaplex chassis into a standard 19" RETMA rack
and apply the AC input power.
Step 1 Remove the slides from the chassis by sliding the slides out until the rear retaining spring buttons
engage. Depress the buttons and slip the slides completely free from the chassis. Set the chassis
aside.
Step 2 Remove the small claw brackets from the package and loosely fasten them, with the teeth facing
out, to the front and rear of the outer slides using 10-32 x 1/2" screws. Notice that the bracket has
slotted holes for adjustment. Use the locking hex nuts provided to secure the screws.
