Uni-Com E-1800 R5 Use and care manual
The replacement of a single FAILED drive can be done while the application is still
running. It does not require the appliance to be turned OFF or the operating system
(OS) to be shutdown. These are hot-swappable hard disk drives that can be removed
and re-installed while power is ON. The appliance will automatically detect the
removal of a FAILED or defective drive and the installation of its replacement.
This is an appliance with RAID storage. Single hard drive failures do not result in an
appliance failure. It will operate in the DEGRADED state until a replacement drive is
installed and a REBUILD of that drive’s data is complete. When the REBUILD is done,
the appliance returns to the OPTIMAL state.
Hardware Configuration
It is possible that one or two disks, depending on the RAID type, could be marked as
bad and the RAID marked as degraded, but this will not affect the appliance’s
ability to operate.

Step 7: Press firmly on the
drive once the handle is locked
to ensure that the drive is fully
engaged.
Step 8: After replacing the failed disk, the green and amber LEDs of the new disk will
start to blink which indicates that the mirror is rebuilding.
If one were to reboot and enter the RAID firmware they would see the current percentage
of the rebuild. Once the rebuild has completed, the RAID will be marked as “Optimal” in the
firmware utility and the amber led will be off. The front bezel can now be replaced.

Replacement / Installation Instructions
BEFORE YOU BEGIN, READ THIS!
CAUTION
Removal of any other drives during this procedure or
during the REBUILD will result in system failure.
NOTE: This is a generic replacement/installation guide. Your appliance
may be different than what is shown in this document.
Failed drive
Static-Sensitive Devices
Electrostatic discharge (ESD) can damage electronic components. To prevent damage to
any printed circuit boards (PCBs), it is important to handle them very carefully. The
following measures are generally sufficient to protect your equipment from ESD damage.
CAUTION
nBe sure that the appliance is properly grounded to the chassis
ground through the AC power cord or enclosure frame.
nTouch a grounded metal object before removing drive from the
antistatic bag.
nHandle drive by its edges only; do not touch components on
the bottom.
CAUTION
Removal of any drive that does not have a red light during this
procedure, or during the REBUILD will result in system failure.
WARNING
Disk drives are static sensitive devices. Please make proper use
of the wrist strap included in the disk FRU kit.
Step 1: First remove the
front bezel if installed to
expose the disk drives. When
looking at the front of the
appliance, the failed disk
drive will have an illuminated
amber LED on the disk sled.
The failed LED is on the top.
Step 2: Press the green release
button located beside the drive’s
LEDs on the failed drive to unlatch
the handle.
Step 3: Swing the handle fully
out to disengage the drive.
Step 4: Slide the drive half way
out of the drive bay and wait for it
to spin down.
Allow 10-20 seconds before
removing the drive from the
drive bay.
