Removing and Installing a Hard Disk
Problem
The JA1500 appliance ships with three hard disk drives in RAID 5 array. The hot-swappable and hot-insertable drives are externally accessible in field-replaceable trays. You can remove and replace a hard disk without powering off the appliance or disrupting functions
If one drive fails, the appliance recovers by automatically rebuilding the failed drive. During failure, the LED 2 on the right on the front of the hard disk tray turns solid red and an alarm sounds . See Figure 10.

Solution
Before you begin removing a hard drive from a JA1500 appliance, ensure that you have taken the necessary precautions to prevent ESD damage.
To remove a failed hard disk and install a new one:
- Place an antistatic bag on a flat surface.
- Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the JA1500 appliance
- Loosen the hard disk captive screws. See Figure 11.

- Slide the hard disk tray out of the appliance.
- Put the failed hard disk in the antistatic bag for return material authorization (RMA).
- Remove the new hard disk from the antistatic bag.
- Insert the new hard disk into the JA1500 appliance
and secure the two captive screws. See Figure 12.

The alarm silences and LED 2 starts blinking indicating the new hard drive is recovering RAID volume. LED 2 stops blinking when the drive rebuilding is complete and normal operation is established.
