4 Replacing Hardware
This chapter provides procedures for replacing components in your Avid ISIS 1000.
c
Do not lift the Engine by the handles on the power supply units—they are not designed to take the weight.
c
Always have available a replacement or blank module before removing the old module. When you replace a
module, you must never leave a bay empty for more than 10 minutes.
c
Use a suitable anti-static wrist or ankle strap and observe all conventional ESD precautions when handling
plug-in modules and components.
You can replace most hardware components without disrupting the system operation. If the Engine has a single
Storage Controller which fails, you must shut down the entire system to replace the failed Storage Controller.
Hardware Faults
LED colors are used consistently throughout the Engine and its components for indicating status:
• Green – good or positive indication
• Flashing green/amber – non-critical condition
•Amber – fault
Make sure that you have obtained a replacement module before removing any faulty module.
c
Observe all conventional ESD precautions when handling Engine modules and components.
Removing the Bezel
On the ISIS 1000 Engines, you must remove the bezel to access the media drives.
To remove the bezel:
t Insert your fingers into the rectangular openings on the front of the bezel and gently pull. The bezel is held in
place by small plastic tabs that latch onto the face of the Engine.
t To reattach the bezel, gently snap it onto the front of the Engine.
Replacing a Drive
When a system drive or a drive in a Media Pack fails, the drive fault LED illuminates; see “Media Pack and
System Drives” on page 2
. The Media Pack status changes to Drive rebuilding .
c
If you remove the wrong drive by mistake while the Media Pack is already rebuilding data from a failed
drive, and while client I/O is still active, all client activity might stop after a brief delay while the system
starts a second rebuild process. You can safely reinsert the drive and remove the correct failed drive.
