2 Hardware Installation
2.4 Before You Start
Some components are configured into fault-tolerant pairs and are independently
hot-swappable while the failure of other components such as server board or the RAID
controller can cause a down time.
NOTE
Always install the enclosure onto the rack before installing hard drives into the
enclosure!
2.4.1
Slide rail installation (optional)
The slide rail is an optional accessory and is not included with the 1U EonNAS
systems but is included as a standard kit with 2U EonNAS systems. However if your
rack / cabinet has sufficient means to support 2U
, then you do
not need to install the slide rail included.
2.4.2
Hot-swappable components
HDDs in drive trays (RAID-5 configuration allows 1 hard drive to fail at any given time
without data lost; RAID-6 configuration allows 2 hard drives to fail at the same time at
any given time without data lost. Please refer to the Software Operation Manual for
RAID configuration details and the maintenance section of this manual on how to
replace hard disk drives)
2.4.3
Airflow concerns
Allow 20cm of ventilation clearance in front and rear of the enclosure. Make sure
cables are also placed well clear of the ventilation area behind the enclosure.
