c) At the back of the chassis, disconnect the two power cords.
In the image above, the power cords are connected to the PSUs labeled
P1
and
P2
.
d) At the back of the chassis, depress both rail slides inwards, and push the chassis towards the front of the rack,
until the rails pass the safety catch (about 3"/7.6cm).
e) At the front of the chassis, slowly slide the chassis out until you reach the
pull-safety
at the midway point (you
will hear a soft clicking sound, and feel the chassis "catch" on the rails).
f) Disengage the
pull-safety
on both sides of the chassis and slide it out until the split line of the two top covers.
Push the
pull-safety
on one side up, and the
pull-safety
on the other side down.
g) Continue to slowly slide the chassis out until you reach the
pull-safety
at the end point, and disengage it as you
did the earlier one.
h) Safely unmount the chassis from the rack and place it on a table.
Caution:
A Controller Node chassis weighs about 50lbs. Ensure that you have sufficient
manpower to handle it safely.
Warning:
Once you pull the chassis past the
pull-safety
, do not leave it hanging in the rack.
Otherwise, the rack rails may be damaged permanently.

Move the two HDDs and the four SSDs from the failed chassis to the
exact corresponding slots
in the new
chassis.
Tip:
Write down the disk serial number and slot location so that you can double-check that each
disk is seated in the correct slot post installation into the new chassis.
a) Remove each disk from its slot in the front bay of the failed chassis.
