A.1 Installing the Air Baffles

This section provides procedures for installing the two-piece air baffle into the

• SPARCcluster 1000 node cabinet housing the servers and SPARCstorage arrays (cabinet A)
• expansion cabinet housing SPARCstorage arrays

A.1.1 Side Baffle

1. Loosely thread screws into hole 79 at the front and rear of the cabinet.

   These will accept the slotted holes in the side baffle. See Figure A-1.

2. Orient the side baffle as shown in Figure A-1 and slip the slotted holes over the screw heads installed in hole 79 (2 places).

3. Tighten both screws to secure the side baffle in place.

Figure A-1

A.1.2 Front Baffle

1. Loosely thread screws into holes 78 and 83 at the front of the cabinet.

   These screws will accept the slotted holes in the front baffle. See Figure A-1.

2. Engage the front baffle to the side baffle.

   Orient the side baffle as shown in Figure A-1 and slip the tabs into the slotted holes in the side baffle. Hold the front baffle on a slight angle to allow the tabs to slip in.

3. Swing the front baffle flush against the cabinet and slip the slotted holes in the baffle over the screws installed in step 1.

4. Tighten both screws to secure the front baffle in place.

A.2 Rack Mount Rail Installation

The rack mount rails are required when installing

• SPARCstorage array chassis into the SPARCcenter 2000E cabinet, or
• SPARCstorage array and SPARCserver 1000E chassis into the expansion cabinet

The kit consists of the side rails and base plate (identified in Figure A-2) along with fasteners and certain other items. Rail installation consists of

• Installing the side rails in the cabinet to accept the chassis
• Installing the base plate on the storage or server chassis
• Installing the chassis (with base plate attached) on side rails in the cabinet
• Reconfiguring the fan assemblies to provide correct cooling

A.3 Chassis Installation Positions

---

Note - Cabinet cooling is an important factor. Install only SPARCstorage array and SPARCserver 1000E type chassis in the SPARCcluster 1000 or 2000 High Availability or expansion cabinets.

Use only the hole numbers specified for installing side rails. These hole numbers determine chassis spacing for proper ventilation and cooling.

---

A.3.1 SPARCcluster 1000 High Availability Node Cabinets

SPARCstorage Array chassis are installed in the bottom three positions. The server chassis are installed above these in the top two positions. A typical installation is shown in Figure A-3. Side rails are installed using screw hole positions identified in Figure A-3.

---

Note - SPARCstorage array positions in the expansion cabinet are shown in Figure A-6.

---

A.3.2 SPARCcluster 2000 High Availability Node Cabinets

SPARCstorage arrays are installed in following positions:

• Primary cabinet: the bottom two positions, Figure A-4
• Secondary cabinet:

  minimum-configuration: the third SPARCstorage array occupies the top position, Figure A-5

  four or more SPARCstorage arrays, the bottom two positions, Figure A-4

---

Note - Any additional SPARCstorage arrays are installed in one or more expansion cabinets.

---

A typical installation is shown in Figure A-4. Side rails hole numbers are identified here.

---

Note - The rails are asymmetrical front-to-rear with respect to the lower hole position used. So, the hole used in the rear is one lower than that in the front

---

---

Note - SPARCstorage array positions in the expansion cabinet are shown in Figure A-6.

---

A.3.3 Expansion Cabinets

SPARCstorage Array chassis are installed in all five positions. A typical installation is shown in Figure A-6. Side rails are installed using screw hole positions identified in Figure A-6.

A.4 Installing the Side Rails

1. Loosely thread in two screws on the right side of the rack:

   a. At the rear of the rack, thread a screw a few turns into hole 18. b. Thread a screw into hole 18 at the front of the rack.

   Do not tighten. See Figure A-7.

Figure A-7

2. Place the right side rail in the rack. Align the open-slotted holes at the top of the rail with the screws installed in step 1.

3. Slide the rail to the rear so the holes seat on the shafts of the screws.

4. Install screws in the bottom rail holes front and rear. In the rear, it is hole 9, in the front it is hole 10.

   See Figure A-8.

5. Tighten all four screws, top and bottom.

6. Repeat steps 1 through 4 above for the left side rail.

   See Figure A-9.

7. Install all remaining pairs of side rails at the hole numbers specified in Figure A-3, Figure A-4, or Figure A-5.

A.5 Preparing the Server and SPARCstorage Array Chassis

---

Note - Illustrations in this section show a server chassis. A SPARCstorage array chassis looks somewhat different, but the procedures apply to both chassis types.

---

Part of chassis preparation involves removing all plastic panels from each chassis to be installed.

A.5.1 Removing the Front Panel

The front panel rests in a groove along the top edge of the panel.

1. If a key switch is present, remove the key from the key switch.

2. Place your fingers under the arrow embossed on the front panel and press up on the latch to release the panel.

   See Figure A-10.

---

Note - If the panel resists becoming unlatched, press down on the top of the panel with one hand while pressing up on the latch with the other. This should release the latch.

---

3. With the panel released, gently swing the panel bottom away from the chassis and lift it clear.

   Set the panel aside.

Figure A-10

A.5.2 Installing the Key Switch Position Label

---

Note - This procedure applies only to server chassis. This switch is found on the EMI panel. For SPARCstorage array chassis, skip this procedure and proceed to Section A.5.3 (SPARCstorage array chassis do not have key switches).

---

Key position icons embossed on the front panel are removed when the front panel is removed. To restore the key position information to the front of the chassis, install the icon label (supplied in the kit) to the EMI panel.

1. Find the key icon label in the rack kit.

2. Remove the label backing.

3. Orient the label over the EMI panel so that the semicircular cutout straddles the key switch as shown in Figure A-11.

4. Apply the label to the EMI panel.

5. Place the key(s) in a secure place so they can be found later.

---

Note - It is suggested you not insert the key in the switch at this time because the necessary handling of the chassis may inadvertently break off the key.

---

A.5.3 Removing the Side Panels

The side panels are self-attached slide and lock panels.

1. First remove the front panel as described in the previous section.

2. Remove the side panel:

a. Grasp the panel with both hands, and slide it toward the rear of the chassis about 2.5 centimeters (about one inch).

Tap the front edge of the panel with the heel of your hand if necessary to slide the panel toward the rear of the chassis. See Figure A-12.

b. Pull the panel away, free of the chassis, and set it aside.

3. Repeat step 2 to remove the remaining side panel.

A.5.4 Removing the Top Panel

The top panel slides to the rear to a release point, then lifts off.

A.5.4.1 Removing the Popouts

There are four popouts on the top panel:

1. On the panel, find the location where the two dots are adjacent to each other: one dot on the popout, one on the top panel. See Figure A-13.

2. Press down on the popout at the small dot.

3. This action rocks the popout on a hinge-point, unlatching it.

4. Slide the popout back, away from the dots and lift it free as shown in Figure A-13. Set the popout aside.

5. Repeat step 1 through 3 to remove the remaining three popouts from the top panel.

A.5.4.2 Removing the Top Panel

For the steps below refer to Figure A-14.

1. Place your fingers under the panel rear lip and lift.

   Lift with enough force to bow the panel rear up at the center. This action causes three small raised features on the panel underside to clear cutouts in the chassis sheet metal.

2. While lifting the panel rear, tap the front with your hand to slide the panel to the rear.

   Slide the panel a few inches only. This is enough to disengage it from the chassis.

---

Note - If necessary, slide your lifting hand side-to-side under the rear lip while tapping the front to free each of the three raised areas on the panel underside of sheet metal cutouts beneath.

---

3. Lift the top panel straight up, clear of the chassis, and set it aside.

A.5.4.3 Replacing the Popouts

To prevent losing the popouts:

1. Orient the popout so the dots are nearest each other (see Figure A-15).

2. Slide the popout in until it is centered in the hole.

3. Press down on the side opposite the dot to secure the popout in place.

4. Install the remaining three popouts in the same manner.

A.5.4.4 Removing the Feet

1. Invert the chassis. See Figure A-16.

2. Unscrew all four feet.

   The feet and screws are not used in this configuration.

A.5.4.5 Removing the Bottom Panel

The bottom panel is identical to the top panel and is removed in the same manner.

* With the chassis inverted and the front facing you, repeat Section A.5.4.2, "Removing the Top Panel" and refer to Figure A-14.

A.6 Installing the Base Plate on the Server or

Disk Array Chassis

The base plate mounts to the chassis underside.

---

Caution - For this procedure, use only the four short screws provided in the kit for this purpose. The screws originally used for the feet are too long and will damage the chassis.

---

1. Invert the chassis with the front facing you as shown in Figure A-17.

2. Place the base plate on the chassis as shown in Figure A-17.

3. Loosely thread four short screws from the kit in all four holes.

   When all screws are started, tighten them.

4. Restore the chassis to the upright position -- front of chassis facing you.

   See Figure A-18.

A.7 Installing the Chassis in the Cabinet

Install the chassis from the bottom-up in the order shown in Figure A-3.

---

Warning - The cabinet can become front-heavy while installing chassis. Ensure that the stabilizer bar is extended before proceeding. Failure to extend this bar can result in the cabinet tipping forward and injuring personnel.

---

---

Warning - Server and SPARCstorage array chassis are heavy. Obtain the aid of an assistant to help lift the chassis. Attempting to lift the chassis alone can result in injury to personnel.

---

1. With the aid of an assistant, lift the chassis (one person on each side) and approach the expansion cabinet with the chassis facing end first.

   See Figure A-19.

2. Line up the chassis base plate with mating side rails in the cabinet.

   See Figure A-20.

3. Rest the chassis on the side rails, then slide the chassis in.

4. Thread in a screw through the slotted hole in the front of the base plate, into the left and right side rail.

5. At the cabinet rear, insert screws through the holes in the rear of the side rails and screw them into threaded holes in the base plate.

   See Figure A-21.

6. Alternately tighten the screws at the front and rear of the of the base plate/side rails until the chassis/base plate is firmly clamped in the side rails. Do this on both sides of the Cabinet.

7. Repeat steps 1 through 6 for all remaining chassis to be installed.

---

Note - At this time, you may decide to

• · Insert the keys in the server chassis key switches for ready use.
• · Store the keys for use only when needed.

A.8 Installing the Blower Assemblies

Install two blower assemblies in the front of all SPARCcluster 1000 High Availability and SPARCstorage array cabinets.

1. Remove the top two vented front panels.

2. Remove two small EMI panels in the upper and lower right areas of the cabinet.

   Discard these panels. They will not be reused.

3. Locate the blower assemblies.

   See Figure A-22.

4. Plug the female end of the power cords into the back of the blower assemblies.

   The power connector is identified in Figure A-22.

5. Install the upper blower assembly:

   a. Lead the power cord through the opening.

   Allow it to collect inside the cabinet for the moment.

   b. Place the blower assembly in the opening in the cabinet sheet metal.

   Tilt the unit and insert the bottom of the blower through the opening so that retainer features at the bottom of the blower assembly engage the sheet metal at the bottom of the opening. See Figure A-23.

   c. Secure the blower assembly to the cabinet.

   Tilt the unit up flush against the cabinet.

   d. Install four screws, two at the top and two at the bottom and tighten.

Figure A-23

High Availability and Expansion Cabinet

---

Note - The blower assembly may encounter mechanical interference from a screw securing the plate holding the cabinet key switch. If this occurs, remove the screw causing the interference, secure the blower to the cabinet using all four screws, then reinstall the screw in the key switch plate.

---

6. Install the lower blower assembly.

   Repeat step 5 above, but for the lower blower assembly.

7. Secure the power cords inside the cabinet.

   Dress the power cords down the inside of the rack to the vicinity of the AC power sequencer and secure them using cable ties. Roll any excess cord and tuck it into the space under the power sequencer and secure using cable ties.

8. Plug in the blower assemblies.

   Plug the power cords into the rear of the power sequencer. Use the unswitched outlets identified in Figure A-24.

Air baffle, rack mount rail and blower assembly installation are complete.
