RES-XR4-3U Installation Manual Version 1.3
2.1.5.3 Storage Drive Installation
To install a storage drive,
1. Make sure the latch handle of the drive to be installed is in the open position.
2. Properly orient the new drive and insert it into the vacant drive slot.
3. Push the drive toward the rear (DO NOT CLOSE the latch handle while push-
ing) until the drive is flush with the front of the chassis. The handle will swing
closed when it comes into contact with the RES-XR4-3U chassis.
4. When the drive is fully inserted in its slot, insert the key into the barrel lock
and turn it 45 degrees counter-clockwise. The drive is now locked.
5. If you are installing another storage drive, repeat Steps 1–4 for each additional
drive.
2.1.6 Removable 120-mm Fan
The RES-XR4-3U contains two high-speed 120-mm fans. Both fans are removable
for replacement in case of a fan failure.
Caution: When in the closed position, the latch handle secures the drive to the
chassis. If the handle is closed before the drive is fully inserted, the latch mechanism
may not fully engage to secure the drive.
Note: Since RES-XR4-3U fans are “hot-swappable”, it is not necessary to turn
off system power in order to remove and replace a fan,
Caution: When replacing the 120-mm fans, do not leave the fan lid open for more
than 3 minutes, as this will cause an undesirable drop in chassis pressure (bad for
temperature stability). In the event of a catastrophic fan failure (all fans cease to
function) it is highly advised that the system be powered down first, then take action
to replace the fans.
