CHAPTER 1
Installing a Power Distribution
System
Installing a power distribution system in a Sun Rack consists of three steps:
■“Installing Cable Harnesses” on page 1-1
■“Installing Power Strips” on page 1-6
■“Installing Power Sequencers” on page 1-7
Additionally, once systems are installed in the rack, you may label the system power
cords with the labels provided.
Installing Cable Harnesses
Each cable harness consists of three cables bundled together on a carrier plate.
Viewed from the back of the rack, the cable harnesses and power sequencers are
mounted on the left side of the rack. The lower cable harness (B) is shorter than the
upper harness (A). Each cable carrier plate is installed in the slot above its respective
sequencer. It is more convenient to install the cables for the lower sequencer (B) first.

1. Remove the power strip bracket cover, and the power strip bracket, and the rack
side panel.
Chapter 1 Installing a Power Distribution System 1-3
2. Holding the carrier plate, pass the cable bundle through the space between the
outer frame and the rack mounting rail.
FIGURE 1-1 Cable Harness and Carrier Plate
After the cable ends are inserted, insert the carrier plate and push it forward
towards the front of the rack. As you slide the carrier plate in, the front end is
guided by a vertical channel on the front cover plate.
As the carrier is close to being fully inserted, a small tab on its bottom edge aligns
with a slot in the channel to position the carrier to the right. As this tab fully engages
a small vertical slot in the carrier plate engages and allows the carrier to drop into its
final position. At this point tighten the captive screw.
3. Repeat Step 2 for the upper cable harness (A).

4. Attach the two connector clusters to the power input panel.
FIGURE 1-2 Attaching Connector Clusters to the Power input Panel
Mount the lower cable harness cluster (B) on the right side of the input panel.
Position each cluster under the power input panel with the open side up. (The cables
are positioned on the left side of the power input panel.) The connectors engage with
the slots in the front surface. Secure each cluster with a single screw between the two
connectors.
While attaching the left-hand cluster (A) to the power input panel, ensure that the
cluster supports the two cables from the right-hand cluster (B).

5. Attach the input power panel to the rack with two 8 mm screws, split washers,
and flat washers.

6. Reinstall the power strip mounting bracket and the power strip mounting bracket
cover.

Installing Power Strips
Power strip B is mounted forward of power strip A, and so must be installed first.
FIGURE 1-4 Installing a Power Strip
1. If you have not already done so, reinstall the power strip mounting bracket and
the power strip mounting bracket cover.
2. Connect cable B to the connector on the bottom of power strip B.
Five notches on the socket side of the connector line up with five keys on the
plug side of the connector to ensure proper alignment. The master (large) key on
the power strip is on the power strip bracket side of the connector.
Alternately, you may attach the connector after the power strip is installed.
3. Holding the top of the power strip away from the rack, insert the tab on the
bottom of the power strip into the slot on the bottom of the power strip mounting
bracket.
4. Slide the tab on the top of the power strip into the slot on the top of the power
strip mounting bracket. Tighten the securing screw at the top of the power strip
mounting bracket.
5. Repeat Step 2 through Step 4 for power strip A.
6. Apply the provided labels “A” and “B” to their respective power strips.
