Installing the Server Into a Rack

5 Installing the Server Into a Rack

This section describes how to install the server into a rack using the slide-rail assembly in the Rackmount Kit.

Rackmount procedure figures depict Oracle Server X9-2L. Rackmount procedures are the same for Oracle Server X9-2.

Note:

In this guide, the term "rack" means either an open rack or a closed cabinet.

Installation Procedure

Preparing for Server Installation

Installation Prerequisites

Before you start the rackmount procedures, ensure that the following tasks are complete:

Install optional components purchased for the server. See Optional Component Installation.
Confirm that your site meets the required electrical and environmental requirements. See Preparing for Server Installation.

Safety Precautions

This section describes safety precautions you must follow when installing the server into a rack.

Caution:

Observe these safety precautions:

Leveling feet position: When unpacking the rack at the installation site, or when repackaging and moving the rack to a new location, verify that the leveling feet are up before moving the rack.

Shipping brackets: The rack shipping brackets are not for use for bracing or anchoring the rack during seismic events.

Stabilize rack: Deploy the anti-tilt bar on the equipment rack before starting an installation.

Equipment loading: Always load equipment into a rack from the bottom up so that the rack does not become top-heavy and tip over. Deploy your rack anti-tilt bar to prevent the rack from tipping during equipment installation.

Lifting equipment: Oracle Server X9-2 weighs approximately 45 lbs (20.41 kg). Oracle Server X9-2L weighs 73 lbs (33.11 kg). Two people are needed to mount either server into the rack enclosure.

Figure showing that two people are needed to lift the server.

Communicate instructions: When performing a two-person procedure, communicate your intentions clearly to the other person before, during, and after each step to minimize confusion.

Elevated operating ambient temperature: If you install the server in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment might be higher than the room ambient temperature. Install the equipment in an environment compatible with the maximum ambient temperature (Tma) specified for the server. For server environmental requirements, see Environmental Requirements.

Reduced airflow: Install the equipment in a rack so that it does not compromise the amount of airflow required for safe operation of the equipment.

Mechanical loading: Mount the equipment in the rack so that it does not cause a hazardous condition due to uneven mechanical loading.

Circuit overloading: Consider the connection of the equipment to the supply circuit and the effect that overloading the circuits might have on over-current protection and supply wiring. Also consider the equipment nameplate power ratings used when you address this concern.

Reliable earthing: Maintain reliable earthing of rackmounted equipment. Pay attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Mounted equipment: Do not use slide-rail-mounted equipment as a shelf or a workspace.

ESD Precautions

Electronic equipment is susceptible to damage by static electricity. To prevent electrostatic discharge (ESD) when you install or service the server:

Use a grounded antistatic wrist strap, foot strap, or equivalent safety equipment.
Place components on an antistatic surface, such as an antistatic discharge mat or an antistatic bag.
Wear an antistatic grounding wrist strap connected to a metal surface on the chassis when you work on system components.

Caution:

Equipment damage: Electrostatic damage can permanently disable the system or require repair by authorized service technicians.

Before installing the server, read the safety information in Oracle Server Safety and Compliance Guide and in Important Safety Information for Oracle's Hardware Systems.

Rackmounting the Server

To rackmount the server, secure the rack to the floor, stabilize the rack, and install the mounting brackets and slide rails. Then, install the server into the rack.

Stabilize the Rack

Caution:

To reduce the risk of personal injury, stabilize the rack cabinet, and extend the anti-tilt bar before you install the server.

Refer to your rack documentation for detailed instructions for the following steps.

Open and remove the front and back doors from the rack cabinet, only if they impinge on the mounting bay.
To prevent the rack cabinet from tipping during the installation, fully extend the rack cabinet anti-tilt bar, which is located at the bottom front of the rack cabinet.
If the rack includes leveling feet beneath the rack cabinet to prevent the rack from rolling, extend these leveling feet fully downward to the floor.

Caution:

When moving the rack cabinet to a new location, verify that the leveling feet are up before moving the rack.

Install Mounting Brackets on the Server

To install the mounting brackets on the sides of the server:

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.

Figure showing the mounting bracket aligned with server chassis locating pins.

Call Out	Description

Attach the Slide-Rails

Install AC Power Cables and Slide-Rails

Before you install the slide-rails into the rack, install server right-angle AC power cables into the left-side and right-side PDU electrical sockets.

Use the following 2-meter right-angle AC power cable for this procedure:

7079727 - Pwrcord, Jmpr, Bulk, SR2, 2m, C14RA, 10A, C13
Install the slide-rails into the rack.

See Attach the Slide-Rails.

Attach the Slide-Rails

Use this procedure to attach slide-rail assemblies to the rack.

Note:

Before you install the slide-rails, be sure to install the server right-angle AC power cables (part number 7079727 - Pwrcord, Jmpr, Bulk, SR2, 2m, C14RA, 10A, C13). In the 1000 mm rack, the standard rail kit slide-rails obstruct access to the front of the 15kVA, 22kVA, and 24kVA Power Distribution Unit (PDU) electrical sockets. If you use the standard AC power cables, first plug them in, and then install the slide-rails into the rack. After you install the slide-rails, you cannot disconnect or remove the standard AC power cables from the PDU but you can remove them from the system.

Orient the slide-rail assembly so that the ball-bearing track is forward and locked in place.

Simultaneously push and hold the green slide-rail release buttons on each mounting bracket while you push the server into the rack. Continue pushing the server into the rack until the slide-rail locks (on the front of the mounting brackets) engage the slide-rail assemblies with an audible click.

Caution:

Before you install the optional cable management arm verify that the server is securely mounted in the rack and that the slide-rail locks are engaged with the mounting brackets.

Install the Cable Management Arm (Optional)

Follow this procedure to install the cable management arm (CMA), which you can use to manage cables connected to the back of the server.

Note:

Before you install the CMA, ensure that the right-angle AC power cables are long enough to connect to the rackmounted servers when routed through the CMA.

Unpack the CMA, which contains the following components.

Call Out	Description
1	Connector A
2	Front slide bar
3	Velcro straps (6)
4	Connector B
5	Connector C
6	Connector D
7	Slide-rail latching bracket (used with connector D)
8	Back slide bar
9	Server flat cable covers
10	Server round cable covers (optional)

Prepare the CMA for installation.
1. Ensure that you install the flat cable covers for your server on the CMA.
2. Ensure that the six Velcro straps are threaded into the CMA.
  
  Note:
  
  Ensure that the two Velcro straps located on the front slide bar are threaded through the opening in the top of the slide bar, as shown in the illustration in Step 1. This prevents the Velcro straps from interfering with the expansion and contraction of the slide bar when the server is extended out of the rack and returned to the rack.
3. To make it easier to install the CMA, extend the server approximately 13 cm (5 inches) out of the front of the rack.
4. Take the CMA to the back of the equipment rack, and ensure that you have adequate room to work at the back of the server.
  
  Note:
  
  References to "left" or "right" in this procedure assume that you are facing the back of the equipment rack.
  
  Note:
  
  Throughout this installation procedure, support the CMA and do not allow it to hang under its own weight until it is secured at all four attachment points.

To install CMA connector A into the left slide-rail:

Insert CMA connector A into the front slot on the left slide-rail until it locks into place with an audible click [1 and 2].

The connector A tab (callout 1) goes into the slide-rail front slot (callout 2).

To prepare CMA connector D for installation, remove the tape that secures the slide-rail latching bracket to connector D, and ensure that the latching bracket is properly aligned with connector D [1 and 2].

Note:

The CMA is shipped with the slide-rail latching bracket taped to connector D. You must remove the tape before you install this connector.
To install CMA connector D into the left slide-rail:
1. While holding the slide-rail latching bracket in place, insert connector D and its associated slide-rail latching bracket into the left slide-rail until connector D locks into place with an audible click [1 and 2].
  
  Note:
  
  When inserting connector D into the slide-rail, the preferred and easier method is to install connector D and the latching bracket as one assembly into the slide-rail.
2. Gently tug on the left side of the CMA back slide bar to verify that connector D is properly seated.
  
  Note:
  
  The slide-rail latching bracket has a green release tab. Use the tab to release and remove the latching bracket so that you can remove connector D.
Gently tug on the four CMA connection points to ensure that the CMA connectors are fully seated before you allow the CMA to hang by its own weight.
To verify that the slide-rails and the CMA are operating properly before routing cables through the CMA:
1. Ensure that the rack anti-tilt bar is extended to prevent the rack from tipping forward when the server is extended.
  
  Caution:
  
  To reduce the risk of personal injury, stabilize the rack cabinet and extend the anti-tilt bar before extending the server from the rack.
  
  For instructions to stabilize the rack, see Stabilize the Rack.
2. Slowly pull the server out of the rack until the slide-rails reach their stops.
3. Inspect the attached cables for any binding or kinks.
4. Verify that the CMA extends fully with the slide-rails.
To return the server to the rack:
1. Simultaneously pull and hold the two green release tabs (one on each side of the server) toward the front of the server while you push the server into the rack. As you push the server into the rack, verify that the CMA retracts without binding.
2. To pull the green release tabs, place your finger in the center of each tab, not on the end, and apply pressure as you pull the tab toward the front of the server.
3. Continue pushing the server into the rack until the slide-rail locks (on the front of the server) engage the slide-rail assemblies.
  
  You hear a click when the server is in the normal rack position.
Connect cables to the server, as required.

See Connecting Cables and Applying Power.
Open the CMA cable covers, route the server cables through the CMA cable troughs (in the order specified in the following steps), close the cable covers, and secure the cables with the six Velcro straps.
1. First through the front-most cable trough.
2. Then through the small cable trough.
3. Then through the back-most cable trough.
  
  Caution:
  
  When securing the cables with the Velcro straps located on the front slide bar, ensure that the Velcro straps do not wrap around the bottom of the slide bar. Otherwise, expansion and contraction of the slide bar might be hindered when the server is extended from the rack and returned to the rack.
Ensure that the secured cables do not extend above the top or below the bottom of the server to which they are attached.

Otherwise, the cables might snag on other equipment installed in the rack when the server is extended from the rack or returned to the rack.
If necessary, bundle the cables with additional Velcro straps to ensure that they stay clear of other equipment.

Note:

If you need to install additional Velcro straps, wrap the straps around the cables only, not around any of the CMA components. Otherwise, expansion and contraction of the CMA slide bars might be hindered when the server is extended from the rack and returned to the rack.

Remove the Cable Management Arm

Follow this procedure to remove the cable management arm (CMA).

Before you begin this procedure, refer to the illustration provided in Step 1 in the procedure Install the Cable Management Arm (Optional) to identify CMA connectors A, B, C, and D. Disconnect the CMA connectors in the reverse order in which you installed them, that is, disconnect connector D first, followed by C, B, and A.

Throughout this procedure, after you disconnect any of the CMA four connectors, do not allow the CMA to hang under its own weight.

Note:

References to “left” or “right” in this procedure assume that you are facing the back of the equipment rack.

To prevent the rack from tipping forward when the server is extended, ensure that the rack anti-tilt bar is extended.

Caution:

To reduce the risk of personal injury, stabilize the rack cabinet and extend the anti-tilt bar before extending the server from the rack.

For instructions to stabilize the rack, see Stabilize the Rack.
To make it easier to remove the CMA, extend the server approximately 13 cm (5 inches) out of the front of the rack.
To remove the cables from the CMA:
1. Disconnect all cables from the back of the server.
2. If applicable, remove any additional Velcro straps that were installed to bundle the cables.
3. Unwrap the six Velcro straps that are securing the cables.
4. Open the three cable covers to the fully opened position.
5. Remove the cables from the CMA and set them aside.

To disconnect connector D:
