Disassembly/Reassembly

Description

This section demonstrates disassembly procedures for all field replaceable units (FRUs) and then addresses the specific issues relevant to reassembly of the CLARiiON CX600 xPE and DAE.

Objectives

The following are the objectives for this exercise:

Disassemble a CLARiiON CX600 xPE and DAE to the FRU level. Recognize the FRUs for a CLARiiON CX600 xPE and DAE and identify FRU replacement dependencies. Completely reassemble a CLARiiON CX600 xPE and DAE to the point of ready to power up.Tools/Aids/Materials

The following tools/aids/materials are required to disassemble and re-assemble Fibre Channel Disk Enclosures.

The procedures for removing each FRU are contained in a separate table. Component removal dependencies and a list of applicable enclosures can be found at the beginning of each table.

List of Field Replaceable Units

The CLARiiON CX600 SPE includes the following FRUs:

FRUDescription

Front BezelFront cover of the CX600 chassis.

Power SupplyCoverts AC power to DC and supplies power to the electronics and disks within the enclosure.

Storage ProcessorProcessor board for an xPE that provides RAID processing, read cache, and write cache.

Storage Processor Fan PackMetal fan pack that cools the storage processors.

Standby Power SourceProvides battery backup power to preserve the write cache on a storage processor in the event of a loss of supply power.

Removing the Front Bezel

Follow this procedure to remove the front bezel:


1. Press in on the release buttons and pull the bezel away from the chassis.

Removing the Power Supplies

Follow this procedure to remove the power supplies:


2. Make sure the switch on the power supply is in the OFF position, and wait five seconds before disconnecting the power cable.

3. CAUTION: The orientation of the two power supplies is different. Pay close attention when removing a power supply to make sure that you orient it correctly when replacing it.

Release the retaining clip from the power cord and disconnect the cord from the power supply.

4. Loosen the thumbscrew securing the power supply to the chassis. Notice the securing mechanism is a latch (see arrow below) and the screw only need be turned about 1 turn to free the power supply. The icons beside the screw dictate the direction to turn the screw.

5. Slide the power supply out of the chassis.

Removing the Storage Processors (SPs)

Follow this procedure to remove the storage processors:

Removing the Storage Processors

1. Disconnect all cables from the back of the SP, including the Fibre Channel, terminal, and SPS cables.

2. CAUTION: The orientation of the two Storage Processors is different. Pay close attention when removing a Storage Processor to make sure that you orient it correctly when replacing it.

Loosen the two captive thumbscrews that secure the SP to the chassis. This is the same latch type mechanism as on the power supplies.

3. Carefully slide the storage processor out of the chassis.

Removing the Storage Processor Fan Pack

Follow this procedure to remove the storage processor fan pack:

Removing the Storage Processor Fan Pack

1. The following procedures should be followed before continuing:


2. Grasp the two plastic locking levers as shown and squeeze the levers towards each other.

3. CAUTION: The storage processor fan pack should be replaced within two minutes if the enclosure is powered on and operational or the storage processors will overheat and force a thermal shutdown.

Press inward on the black plastic locking tabs, and use the handles to pull the SP fan pack out of the enclosure.

Removing the Standby Power Sources

Follow this procedure to remove the standby power sources.

Removing the Standby Power Sources

1. Make sure the power switch on the SPS is in the off position. Disconnect all of the cables from the SPS, including the RJ-11 serial cable and all power cables. Remove the four screws from each mounting plate on the back of the SPS and remove the mounting plates.

2. Pull forward to release the front bezel from the SPS rack tray.

3. Remove the two screws that secure the front of the SPS.

4. CAUTION: Each SPS weighs approximately 20 pounds.Slide the SPS outward from the rear of the rack.

Reassembly of CLARiiON CX600 xPE

Replacing each FRU follows the steps required to remove the FRU in reverse order.

Disassembly of a CLARiiON CX600 DAE

This section covers the procedures necessary to remove and replace parts in a CLARiiON CX600 DAE.

The procedures for removing each FRU are contained in a separate table. Component removal dependencies and a list of applicable enclosures can be found at the beginning of each table.

List of Field Replaceable Units

The CLARiiON CX600 DAE includes the following FRUs:

FRUDescription

Front BezelFront cover of the DAE chassis.

Disk ModuleFibre Channel hard disk drive mounted in a carrier.

Link Control CardProvides an arbitrated loop for the disks within the enclosure, and allows enclosures to be daisy-chained.

Power SupplyConverts AC power to DC and supplies power to the electronics and disks within the enclosure


Follow this procedure to remove the front bezel:


1. Press in on the release buttons.

3.Pull the bezel away from the chassis.

Removing the Disk Modules

Follow this procedure to remove the disk modules:

Removing the Disk Modules

1. CAUTION: A disk module should not be removed while power is applied unless its amber Check LED is illuminated. When removing multiple disk modules, wait several seconds between each removal and verify that the active LEDs of the remaining modules are flickering.

CAUTION: When removing multiple disk modules, make sure to insert the modules into their original slots in the enclosure. If the disk module is a member of a bound LUN, data on that LUN may be inaccessible if the drive is replaced in a different slot.

Press the release latch on the drive carrier, and lift the latch up to unlock the carrier from the chassis.

3.CAUTION: When reinstalling the disk module do not force the module into the slot. Use the latch to fully seat the drive.

Slide the module out of the chassis.


Follow this procedure to remove the disk modules:


1. Loosen the captive thumbscrew securing the power supply to the chassis.

3.Slide the power supply out of the chassis.

Removing the Link Control Cards

Follow this procedure to remove the link control cards:

Removing the Link Control Cards

1. Loosen the thumbscrew securing the link control card to the chassis.

3.Slide the link control card out of the chassis.

Reassembly of the CLARiiON CX600 DAE

Replacing each FRU follows the steps required to remove the FRU in reverse order. Re-connect the cables (not the Fibre Channel cables) and double check them before powering up.End of Lab.Use this page to write down your thoughts and notes.EMC TrainingCX600 Disassembly/Reassembly
