Installing and replacing a hot-swap hard drive

Use the following instructions to install or replace a hot-swap hard drive.

Installing a hot-swap hard drive

Figure 20. Installing a hot-swap drive

To install a drive in a hot-swap hard drive bay:

Attention:

To maintain proper system cooling, do not operate the appliance for more than two minutes without either a hard drive or a filler panel installed for each bay. Therefore, if you are replacing a defective hot-swap drive, either leave the defective drive in place or put in a filler panel until you have a replacement drive.
When you handle electrostatic discharge-sensitive devices (ESDs), take precautions to avoid damage from static electricity. For details on handling these devices, refer to Handling electrostatic discharge-sensitive devices.

Remove the filler panel from one of the empty hot-swap drive bays by inserting your finger into the depression at the left side of the filler panel and pulling it away from the appliance.

Note:

If you are installing a half-high hard drive, you will need to remove two adjacent filler panels. The two filler panels should be from either the top pair of drive bays, the middle pair of drive bays, or the bottom pair of drive bays.

Install the hard drive in the hot-swap drive bay:
1. Ensure that the tray handle is open (that is, perpendicular to the hard drive).
2. Align the rails on the hard drive assembly with the guide rails in the drive bay.
3. Gently push the hard drive assembly into the drive bay until the hard drive connects to the backplane.
4. Push the tray handle toward the closed position until it locks the hard drive in place.
If you installed a half-high hard disk drive, install a slim filler in the gap above the hard drive:
1. Locate the slim filler that is designed for use with these half-high hard drives. It is stored on the empty tray of the filler panel that you removed earlier in this procedure.
2. Pull the slim filler off the filler panel.
3. Gently push the slim filler into place in the gap above the hard drive.
Check the hard drive status indicators to verify that the hard drives are operating properly (the Hard Drive Status LED is immediately to the right of the hard disk drive).
- When the amber LED is on continuously, the hard drive has failed.
- When the green LED flashes slowly (one flash per second), the hard drive is being rebuilt.
- When the green LED flashes rapidly (three flashes per second), the controller is identifying the hard drive.

Note:

If your appliance has a RAID adapter installed, refer to the information provided with the RAID adapter for information about adding a hard drive.

Replacing a hot-swap hard drive

You do not have to switch off the appliance to remove or install the hot-swap hard drives.

Attention:

Before you replace a hot-swap hard drive, check the Hard Drive Status LED on the front of the drive to see if the drive is defective (if the drive is defective, the LED will be amber). If you partially or completely remove a good drive instead of a defective one, you might lose valuable data.
This situation is especially relevant because your appliance has a RAID adapter installed. The RAID adapter can rebuild the data that you need, provided that certain conditions are met.
Before you remove a hot-swap hard drive that is not defective, back up all important data.
To avoid damage to a hard drive, pull on the release lever to disengage the hard drive connector from the backplane at the back of the drive bay, wait approximately 30 seconds to allow the hard drive to spin down, and then completely remove it from the bay.

Refer to Figure 21 while you perform the steps in this procedure.

Figure 21. Replacing a drive in a hot-swap drive bay in the Model 100

To replace a drive in a hot-swap drive bay:

Before you begin, do the following:

If your appliance is a Model 100, unlock and open the appliance door.
Attention: To maintain proper system cooling, do not operate the appliance for more than two minutes without either a hard drive or a filler panel installed for each drive bay.
Locate the defective hard drive (look for an amber Hard Drive Status LED on the front of the drive).
Remove the defective hard drive: move the handle on the hard drive to the open position (perpendicular to the hard drive) and pull the hot-swap hard drive assembly from the drive bay.
Install the replacement hard drive in the hot-swap drive bay:
1. Ensure that the tray handle is open (that is, perpendicular to the hard drive).
2. Align the rails on the hard drive assembly with the guide rails in the drive bay.
3. Gently push the hard drive assembly into the drive bay until the hard drive connects to the backplane.
4. Push the tray handle toward the closed position until it locks the hard drive in place.
Check the hard drive status indicators to verify that the hard drive is installed properly (the Hard Drive Status LED is located to the immediate right of the hard disk drive).
- When the amber LED is on continuously, the hard drive has failed.
- If you have a RAID adapter installed:
  - When the green LED flashes slowly (one flash per second), the hard drive is being rebuilt.
  - When the green LED flashes rapidly (three flashes per second), the controller is identifying the hard drive.
If your appliance is a Model 100, close and lock the appliance door.

Installing an IDE (non-hot-swap) hard drive or CD-ROM

Note:

The appliance's electromagnetic interference (EMI) integrity and cooling are both protected by having the non-hot-swap drive bays covered or occupied. When you install a hard disk drive, save the filler panel from the bay in case you later remove the drive and do not replace it with another.

Figure 22. Installing a non-hot-swap hard drive

To install a non-hot-swap hard disk drive (5.25-inch, removable media) in one of the non-hot-swap drive bays:

Review the safety precautions in "Translated safety notices".
Switch off the appliance and peripheral devices and then remove the cover and the bezel (see "Removing the cover (Model 100)" for details).
Remove the filler panel from the bay opening by pulling the filler panel away from the appliance. You do not need the filler panel when you have a hard drive installed in the drive bay.
If the drive is a laser product, observe the following safety precaution:

Caution:
When laser products (such as CD-ROMs, DVD-ROM drives, fiber optic devices, or transmitters) are installed, note the following:
DANGER!
Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following.
Laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.
