1 General Information
This manual provides general installation and maintenance information,
including drive installation and power supply replacement for the Megaplex II
9U chassis. The material is arranged into the following sections.
General Description of Chassis
The Megaplex II rack-mount chassis supports up to eight 3.50" SCA (Single
Connector Attachment) Low Voltage Differential (LVD) 16-bit SCSI drives.
SCA drives provide simple installation via pluggable canisters. The SCA “no
cable” design allows you to simply mount the drive into the canister and plug
into the chassis. The Megaplex II chassis includes:
• mounts for up to eight drives,
• mounts for up to three power supplies,
• seven cooling fans,
• four CPU activity LEDs, and
• Alarm Mute LED and Alarm Mute switch.
Peripheral Drives System peripherals include mountings for:
• two 5.25" half-high CD-ROM drives,
• one 3.5" floppy drives, and
• two 3.5" IDE (system drives).
Power Supplies The chassis is supported by three 450W hot-pluggable power supplies. The N+1
redundant arrangement allows the chassis to continue operation when one power
supply fails. The power supply is a modular, pluggable design. Power supplies
are mounted from the rear of the chassis. Each power supply plugs into the
chassis power distribution board via a blind mate connector. The power supplies
are hot-pluggable units that can be replaced while the system remains
operational.
Cooling Cooling is front to rear via three separate removable modular fan assemblies.
Three fan assemblies are provided in the front of the chassis. One external fan
cools the rear of the chassis.
