Servicing Removable Components

Power Supply Unit (PSU)

Insertion

Pull the handle of the PSU so it is at 90° to the main PSU unit. Line up the PSU with the guide rails on the DVAS. Insert the PSU gently until it comes to a halt, then close the handle and secure it in place with the screw (included).

Removal

Turn off the power switch. Disconnect the power cord, loosening the cable clamp if necessary. Loosen the screw on the power supply by turning it counter- clockwise. Pull out the handle of the PSU so that is 90° to the chassis. While supporting the weight of the PSU, use the handle to pull the power supply free from the chassis.

If your DVAS has the dual redundant power supply option, a faulty power supply may be removed and replaced while the unit is operational. Only remove a power supply from a working unit if it is faulty and a replacement is on-site. Removing a PSU when no replacement is immediately available may result in overheating and shutdown. Ensure that the correct PSU is removed; the faulty power supply will not have a green status LED illuminated on its rear panel.

Hard Drive Assemblies

Disk drives are sensitive to static electricity and physical shock. Observe proper ESD precautions and handle with care.

Insertion

Line the disk carrier up to an available disk slot. Be sure the handle is open, and the carrier push button is toward the bottom of the chassis. Push the disk carrier in until it is fully inserted. Close the handle and push in the carrier button to secure it in place.

Removal

Removing a disk while in operation within a RAID set will cause the RAID set to degrade. Only remove a disk which has been marked as bad by the GUI, with an Amber LED illuminated beneath it. To remove a disk, push the button on the disk carrier to release the handle. Gently pull the bottom of the handle toward you and wait ten seconds for the disk to stop spinning. Continue sliding the disk out of the chassis.

RAID Controller

Insertion

A RAID controller should not be inserted while the unit is powered on. If exchanging a faulty RAID controller, schedule a shutdown before replacing it.

Insert the RAID controller into its slot, ensuring that the metal runners line up with the internal guides. Firmly push the RAID controller fully into the chassis until the side clips click into place.

Removal

Do not remove a faulty controller while power is on; power must be disconnected.

Push the side clips securing the controller inwards (toward each other). While supporting the weight of the unit, use the handles to pull the controller free from the unit.
