Step 9 Tighten the thumbscrew and flip the black latch up into a vertical position. 12 Megaplex II Chassis Guide 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. 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. Cont’d Chapter 2 Installation 13 Rack-Mount Installation, Continued Step 3 Position the outer rails in the rack, adjusting the claw brackets and marking the intended position of the mounting holes both on the front and rear of the rack. Tighten the screws on the claw brackets. Step 4 Bolt the front of the slides into place using 10-32 x 1/2" pan head screws. Flat head screws are also provided for racks with countersunk holes. Step 5 Bolt the rear of the slides to the rack side rails using four 10-32 x 3/8" screws. A threaded bracket is provided in case the rack does not have threaded holes. Hex nuts are often difficult to use at the rear of a rack to secure screws. Step 6 Install the chassis slides into the outer slides in the rack. Push the chassis into the rack until the rear retaining spring engages. Then press the retaining buttons and push the chassis the rest of the way into the rack. Step 7 Plug the AC power cord into the AC receptacle on the power supply module. 14 Megaplex II Chassis Guide Field Replaceable Units The field replaceable subassemblies within the Megaplex II chassis are described below. The subassemblies in this section are: · the power supply assemblies and · the fan module assemblies. These assemblies can be ordered as spares from AMI. Power Supply Modules Three 450 watt power supplies support the Megaplex II chassis. The power supplies are located at the rear of the chassis. Each power supply has a power sharing board, which interfaces to the power distribution board located internally in the chassis. DC power is distributed from the power supply module to the power distribution board inside the enclosure and throughout the chassis. Each power supply has an integrated fan. These fans along with the additional chassis fans provide cooling for the chassis. Only the chassis mounted fans are replaceable. Failure of a power supply fan requires replacement of the affected power supply. To replace a power supply follow the procedure below. Chapter 3 Fiel Replaceable Units 15 Replacing a Power Supply The power supply module is hot pluggable. You do not have to shut down the system to replace a power supply. Step 1 Unplug the AC power cord connected to the failed power supply module. Step 2 Loosen the thumbscrews that secure the power supply module. Step 3 Using the handle, remove the power supply module from the chassis. Step 4 Replace the failed power supply module with a new power supply module and tighten the thumbscrews. Step 5 Plug in the AC power cord. 16 Megaplex II Chassis Guide Replacing a Fan Module The chassis mounted fan assembly is easily removed and replaced. Should the fan assembly need replacement use the following procedure. The fan assembly is hot pluggable. You do not have to shut down the system to replace a fan. Step 1 Open the top cover. Step 2 Disconnect the wires and remove the fan assembly. Step 3 Unscrew the fan to be replaced. Step 4 Insert the new fan assembly into place and reconnect the wires. Step ...
