Lock the drive tray.
Turn the bezel lock to the vertical orientation (locked position)
using a flatblade screwdriver. Do not push the bezel lock while turning it,
otherwise the spring handle will pop out again.
NOTE
Never leave the bezel lock unlocked – the RAID controller might consider it as a sign
of faulty drive.

Replacing the Enclosure
Infortrend enclosures are ruggedly constructed and under extremely rare instances
do they incur damages so severe (breakage causing circuit exposure, deformation,
etc.) that require replacing the enclosure. However impossible it may be, the likely
hood of an enclosure needing to be replaced is usually due to a faulty integrated
backplane that separates the front and rear sections of the chassis as mentioned
previously in section
1.2.3 Internal Backplane
. The internal backplane contains a
circuit board that provides logic level signals and low voltage power paths. Thermal
sensors and I
2
C devices are embedded to detect system temperatures and
PSU/cooling module operating status. And as this board contains no
user-serviceable components, when damaged, you will have to replace the entire
enclosure
A faulty backplane board may cause the following:
Falsely report module statuses
Unable to power on some modules or not able to power on the system at all
System
instability
Poor
system
performance
Affect storage data integrity
5.7.1
Differential Diagnosis to Determine Backplane Failure
Apart from obvious damage (circuit exposure, extreme enclosure deformation, etc.),
an indication of enclosure backplane failure can be determined by differential
diagnosis. The simple differential diagnosis will also assist in Infortrend Technical
Support staffs to promptly identify the issue!
