Chapter 5. Installing and replacing components

This chapter provides instructions to help you install or remove customer replaceable units (CRUs), such as hot-swap drives, fans, RAID controllers, and power supplies. This chapter also provides instructions to help you add new DS4000 EXP100 expansion units to existing DS4100 configuration.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

vLimit your movement. Movement can cause static electricity to build up around you.

vHandle the device carefully, holding it by its edges or its frame.

vDo not touch solder joints, pins, or exposed printed circuitry.

vDo not leave the device where others can handle and possibly damage the device.

vWhile the device is still in its static-protective package, touch it to an unpainted metal part of the storage server for at least two seconds. This drains static electricity from the package and from your body.

vRemove the device from its package and install it directly into your storage server without setting it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on your storage server cover or any metal surface.

vTake additional care when handling devices during cold weather because heating reduces indoor humidity and increases static electricity.

Working with hot-swap hard disk drives

Drives are devices that the system uses to store and retrieve data. This section explains how you can increase the storage-server capacity by adding more drives or replacing existing drives with ones containing a larger capacity.

Before you begin, complete the following tasks:

vRead the safety and handling guidelines in “Safety” on page iii and in “Handling static-sensitive devices” on page 18.

vEnsure that your current system configuration is working properly.

vBack up all important data before you make changes to data storage devices.

Attention: Never hot-swap a drive CRU when its green Activity LED is flashing. Hot-swap a drive CRU only when its amber Fault LED is completely on and not flashing or when the drive is inactive with the green Activity LED on and not flashing.
