To remove the filler panels where the servers will be installed, use a No. 2 screwdriver to remove the M6 screws. The number of screws depends on the type of filler panel. Save the screws for future use.
Note:
If you are replacing the filler panels, then do not remove the Duosert cage nuts from the Radio Electronics Television Manufacturers Association (RETMA) rail holes.
Adding New Servers
You can extend Recovery Appliance X7, X6, or X5 to a maximum of 18 storage servers and Recovery Appliance X4 to a maximum of 14 storage servers. You can add any number of storage servers at a time, from one to 15 servers when starting with a minimum configuration.
To prepare for the installation:
-
Identify the rack unit where you will install the server. Fill the first available unit, starting from the bottom of the rack.
See "Recovery Appliance X8, X7, X6, and X5 Rack Layout" or "Recovery Appliance X4 Rack Layout", as applicable.
-
Remove and discard the trough, which attaches the cable harness when no server is installed in the unit.
-
Remove and discard the solid filler.
To install the rail assembly:
-
Position a mounting bracket against the chassis so that the slide-rail lock is at the server front, and the five keyhole openings on the mounting bracket are aligned with the five locating pins on the side of the chassis.
-
Orient the slide-rail assembly so that the ball-bearing track is forward and locked in place.
-
Starting on either side of the rack, align the rear of the slide-rail assembly against the inside of the rear rack rail, and push until the assembly locks into place with an audible click.

Description of "Figure 7-6 Aligning the Side-Rail Assembly With the Rack" -
Align the front of the slide-rail assembly against the outside of the front rack rail, and push until the assembly locks into place and you hear the click.
WARNING:
-
Installing a server requires a minimum of two people or a lift because of the weight of each server. Attempting this procedure alone can result in equipment damage, personal injury, or both.
-
Extend the rack anti-tip bar to prevent the rack from tipping during equipment installation.
-
For Recovery Appliance X4 racks, load the servers from the bottom up, so that the rack does not become top-heavy and tip over. See "Recovery Appliance X4 Rack Layout" for the designated location of each server.
-
For Recovery Appliance X6 or X5 racks, load the servers following the population rules. See "Recovery Appliance RA23, RA21, X8M, and X8 through X5 Population Rules".
To install the server:
-
Read the service label on the top cover of the server before installing a server into the rack.
-
Push the server into the slide rail assembly:
-
Push the slide rails into the slide rail assemblies as far as possible.
-
Position the server so the rear ends of the mounting brackets are aligned with the slide rail assemblies mounted in the equipment rack.

Cabling the Storage Servers
After installing the new storage servers, cable them to the existing equipment.
Note:
-
The existing cable connections in the rack do not change.
-
The blue cables connect to the compute servers, and the black cables connect to the storage servers. These network cables are for the NET0 Ethernet interface port.
-
Attach and route the management cables on the CMA and rear panel for one server at a time. Do not slide out multiple servers.
-
Start from the bottom of the rack, and work upward.
-
Longer hook and loop straps are needed when cabling three CAT5e cables or two twinaxial cables.
To cable the new servers in the rack:
-
Install the cable management arm (CMA):
-
Into the left slide rail, slide CMA connector A until it locks into place with an audible click.
-
Into the right slide rail, slide CMA connector B until it locks into place with an audible click. Then do the same with CMA connector C.
-
-
Insert the cables into their ports through the hook and loop straps, then route the cables into the CMA in this order:
-
Power
-
Ethernet
-
InfiniBand
-
-
Route the cables through the CMA and secure them with hook and loop straps on both sides of each bend in the CMA.
-
Close the crossbar covers to secure the cables in the straightaway.
-
Verify operation of the slide rails and the CMA for each server:
Note:
Oracle recommends that two people do this step: one person to move the server in and out of the rack, and another person to watch the movement of the cables and the CMA.
-
Slowly pull the server out of the rack until the slide rails reach their stops.
-
Inspect the attached cables for any binding or kinks.
-
Verify that the CMA extends fully from the slide rails.
-
-
Push the server back into the rack:
-
Release the two sets of slide rail stops.
-
Locate the levers on the inside of each slide rail, just behind the back panel of the server. They are labeled PUSH.
-
Simultaneously push in both levers and slide the server into the rack, until it stops in approximately 46 cm (18 inches).
-
Verify that the cables and CMA retract without binding.
-
Locate the slide rail release buttons near the front of each mounting bracket.
-
Simultaneously push in both slide rail release buttons and slide the server completely into the rack, until both slide rails engage.
-
-
Dress the cables, and then tie off the cables with the straps. Oracle recommends that you dress the InfiniBand cables in bundles of eight or fewer.
-
Slide each server out and back fully to ensure that the cables are not binding or catching.
-
Repeat the procedure for all servers.
-
Connect the power cables to the power distribution units (PDUs). Ensure the breaker switches are in the OFF position before connecting the power cables. Do not plug the power cables into the facility receptacles now.
