Attention:
devices. To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
v Remove the device from its package and install it directly into the EXP3000
v Take additional care when you handle devices during cold weather. Heating

Working with hot-swap hard disk drives

Before you remove a hard disk drive, review the following information:
Hot-swap hardware
Hard disk drives
Hard disk drive LEDs
new drive or filler panel.

metal part of the EXP3000 for at least 2 seconds. This drains static electricity
from the package and from your body.
without setting down the device. If it is necessary to set down the device, put it
back into its static-protective package. Do not place the device on the EXP3000
or on a metal surface.
reduces indoor humidity and increases static electricity.
You can replace a failed hard disk drive without turning off the EXP3000.
Therefore, you can continue to operate the EXP3000 while a hard disk
drive is removed or installed. These drives are known as hot-swap drives.
The EXP3000 supports IBM SAS or SATA hard disk drives. Each drive
comes preinstalled in a drive tray, ready for installation in the EXP3000. (Do
not detach the drive from the tray.) You can install the drives directly into
the 12 drive bays on the front of the EXP3000. Before you remove any
drives, record the location information for each drive in Table 2 on page 3.
Attention: If you remove a drive, you must reinstall it in the same bay. If
you reinstall a hard disk drive in the wrong bay, you might lose data.
Each hard disk drive has two LEDs that indicate the status of the drive. The
drive LED states and descriptions are shown in the following table.
