There are three parts in the bracket assembly used to
stabilize the 5887 disk
drive enclosure during shipment of the rack that contains the enclosure.
The bracket assembly consists of a large bracket that attaches to
the rack frame and two smaller brackets that secure the two enclosure
services manager (ESM) units.
Prerequisite: A medium size screwdriver is required to complete this
task.
To remove the bracing bracket assembly, follow these
steps:
- Follow these steps to clear the shipping
bracket installation area of cables and cords:
- Find the slotted opening in the small front
bracket (A) below the left enclosure services
manager (ESM) and loosen the power supply cord (B) that
is visible in the opening. Carefully pull the power supply cord up
through the small front bracket opening. When you have removed the
connector end of the power cord through the opening (C),
hang the loose length of cable to one side so that it does not interfere
with your workspace in the shipping bracket installation area. Using
the same technique, remove and hang the right power supply cord. Do
not disconnect or detach the power supply line cords from their attachments
to the rack or to other cables.

the power supply line cords from their shipping position
- Leave the serial-attached SCSI (SAS) cables (D) connected
to the ESM.
Note: In a basic installation of the 5887 disk drive
enclosure, you are not required to remove the SAS cables. However,
if other installation factors require you to remove the SAS cables
from the ESM, label the cables before you disconnect them to ensure
that you can reconnect them correctly at the end of this procedure.
- Loosen the two thumbscrews (A) on
the small front brackets below the ESM units. Remove the brackets
by lifting them up and away from the ESM units.

- Follow these steps to dock and secure the ESM
units:
- Moving one ESM at a time, slide the unit approximately 75 mm (3
in.) toward the chassis.

ESM units toward the chassis
- For one ESM at a time, place your forefingers under the release
levers and pinch the orange lever tips. Release the levers and swing
them into their fully open position.

the ESM release levers
- Moving one ESM at a time, slide the unit into the chassis until
it stops.
Figure 5. Docking the ESM units
- For one ESM at a time, place your thumbs on the tips of the orange
ESM levers and swing the levers into their fully closed and latched
position.

levers
- Using a screwdriver, remove the screw that
attaches the large bracket to the left flange of the rack frame. Remove
the screw that attaches the bracket to right flange.
Note: Keep the
screws that you removed for their reinstallation in step
6.
Figure 7. Removing the screws from the bracket
and rack flanges
- Slide the large bracket toward the rear
of the rack. Lift the bracket with two hands to remove it from the
side rails.
Tip: Save all of the brackets that you have
removed for any future reinstallation and for shipping of the 5887 disk drive
enclosure that might be required.

- Reinstall the screws that you removed
in step 4 by
inserting them into the same holes in the rack frame and side rails
from which you removed them. Tighten the screws with a screwdriver.
- Follow these steps to dock and secure the power
supplies:
- Moving one power supply at a time, slide the unit approximately
75 mm (3 in.) away from the chassis.
Figure 9. Sliding
the power supplies toward the chassis
- For one power supply at a time, rest your right thumb on the orange
release latch beside the unit handle and your fingertips on the handle.
In one motion, squeeze the release latch to the right and swing the
handle down into its fully open position.

- Moving one power supply at a time, slide the unit into the chassis
until it stops.
Figure 11. Docking the power supplies
- Moving one power supply at a time, swing the unit handle up and
into its fully closed position on the release latch.

handle
- Follow these steps to complete the reconnection
of cables and cords:
- Take the power supply line cords that you moved to one side in
step 1.a and
reconnect them to the left power supply and the right power supply.
Figure 13. Connecting the power supply line cords
- Route the power cords through the power cord retention brackets (D) for
strain relief, as shown in the following figure.

the power cords through the cord retention brackets
- If your installation requirements included the removal of the
SAS cables from the ESMs in step 1.b, review the
labeling that you performed and reinstall the cables.
