2 Preparing To Remove the Scalar LTFS Appliance
Preparing To Remove the Scalar LTFS Appliance
Before removing any part, do the following:
• Obtain the required tools:
• #2 PHILLIPS®screw driver
• Materials for labeling cables
• Request the assistance of another person to help you.
WARNING: Whenever you need to lift the Scalar LTFS Appliance, get others to
assist you. To avoid injury, do not attempt to lift the Scalar LTFS
Appliance by yourself. The Scalar LTFS Appliance weighs 57.54
pounds (26.1 kg). Two people are required to lift the unit
Note: You will be replacing only the damaged rails (chassis rails or rack rails)
and not the entire rackmount.
Removing the Chassis and Rails From the Rack
To remove the Scalar LTFS Appliance chassis from the rack, complete the
following steps:
Note: Before you begin this procedure, be sure you powered down the Scalar
LTFS Appliance (see Turning Off the Scalar LTFS Appliance on page 1).
1Label the cables so that you can reconnect them to the correct ports.
2Remove all power, SAS, Ethernet, and Fibre Channel cables from the back of
the Scalar LTFS Appliance.
3Hold the power button in at least 20 seconds to discharge all of the
condensers before opening the Scalar LTFS Appliance.
4Remove the PHILLIPS screws that are securing the Scalar LTFS Appliance to
the front of the rack.
5Press the slide-release lock button on both rails and slide the system from
the rack (see Figure 1).
6Lift up slightly to remove the Scalar LTFS Appliance out of the rail J-slots and
place it on a flat surface.

7To remove the rails, pull the latch release button on the end piece midpoint
and unseat each rail.
Replacing the Rails in the Rack
To replace the rails in the rack, complete the following steps:
Note: When replacing the rails refer to Figure 2 on page 4 for square holes
and Figure 3 on page 5 for round holes.
1Position the left and right rail end pieces labeled FRONT facing inward and
orient each end piece to seat in the holes on the front side of the vertical
rack flanges.
2Align each end piece in the bottom and top holes of the desired U spaces.
3Engage the back end of the rail until it fully sets on the vertical rack flange
and the latch locks into place.
4Repeat Step 1 through Step 3 to position and seat the front end piece on
the vertical rack flange.

Note: When using round hole rails, the Scalar LTFS Appliance may protrude
from the rack by approximately 1/8 inch (0.3175 cm).
5Place the Scalar LTFS Appliance on a level surface and align the four J-slots
on the chassis rails with the corresponding pins on the system. Slide the
chassis rails towards the back of the system until each one locks into place
(see Figure 4 on page 6)
Reinstalling the Chassis in the Rack
To reinstall the Scalar LTFS Appliance chassis back into the rack, complete the
following steps:
WARNING: Ensure that the system is properly supported until the chassis rails
are locked into the slide rails on both sides.

6 Reinstalling the Chassis in the Rack
WARNING: The Scalar LTFS Appliance weighs 37.3 lbs (16.9 KG). Two people
are required to lift the chassis.
1Pull the inner slide rails out of the rack until they lock into place.
2Locate the rear rail standoff on each side of the Scalar LTFS Appliance and
lower them into the rear J-slots on the slide assemblies.
3Rotate the Scalar LTFS Appliance downward until all the rail standoffs are
seated in the J-slots.
4Push the Scalar LTFS Appliance inward until the lock levers click into place.
5Press the slide-release lock button on both rails and slide the system into the
rack.
Note: Figure 4 shows nodes with the bezel; however, the bezel is actually
added after the components are installed in the rack.
