How to remove and replace a Starcat Power Center Plane

Solution

CAP PROBLEM OVERVIEW: Power Center Plane failure

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
Starcat Training
Knowledge of SMS commands

TASK COMPLEXITY: 4

TIME ESTIMATE: 240 minutes

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?

Domains should be ready to be shut down.
Since you will need to store 18 Expanders plus a number of System and IO boards, make sure enough safe and ESD protected storage space is available or order a StarCat Cart as described here: http://crash2.us.oracle.com/bootcamp/nafo_genie.html. Allow at least 48 hours for delivery.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1) Power off the entire system

Shut down all domain
domain_name# shutdown -y -g <seconds> -i 0

Power off all boards except the power supplies, fans, and the SCs.
sc% poweroff

shutdown the spare SC then power off the spare SC from the main SC
spare_sc# shutdown -y -g <seconds> -i 0 sc% poweroff SCx (SCx is the spare SC)

Shut down the main SC
sc# shutdown -y -g <second> -i 0

Power off the AC0 and AC1 circuit breaker for all power supplies
Disconnect the twelve AC power cords
Remove the Power Centerplane from the chassis:
--- From the rear of the system ---

Remove all system expander and the centerplane support board sets.
Remove the Sun Fireplane interconnect ( centerplane ) prior to removing the power centerplane.
Remove fan tray F7, to access the two lower Phillips screws of the DC cable cover, and place on a flat, sturdy, surface.
Remove the DC cable cover by removing the nine Phillips screws from the DC cable cover.
Remove the five (5) ribbon cable power control connectors from the power centerplane.

Disconnect the P1.9 six-wire friction-fit 48V power connector from J1.9 by depressing the end clips.
The P1.9 six-wire friction-fit 48V power connector is found at the cable tie-down panel beneath the power centerplane.
Remove the eighteen voltage-and-return DC power cables from the power centerplane by loosening the captive screw of each cable while pulling back on the lug.
Remove the seven cross-slotted shoulder standoff nuts from the power centerplane.

--- From the front of the system ---
Remove all system expander and the centerplane support board sets.
Remove fan tray F3, to access the two lower Phillips screws of the DC cable cover, and place on a flat, sturdy, surface.
Remove the DC cable cover by removing the nine Phillips screws from the DC cable cover.
Remove the five ribbon cable power control connectors from the power centerplane.
Disconnect the P1.9 six-wire friction-fit 48V power connector from J1.9 by depressing the end clips.
The P1.9 six-wire friction-fit 48V power connector is found at the cable tie-down panel beneath the power centerplane.
Remove the eighteen voltage-and-return DC power cables from the power centerplane by loosening the captive screw of each cable while pulling back on the lug.
Remove the four panhead grounding screws from the power centerplane.
Remove the seven cross-slotted shoulder standoff screws from the front of the power centerplane.
Remove the power centerplane and place on an ESD-protected surface.

Install the Power Centerplane into the chassis (Following the repair procedures described in the service manual)

--- From the front of the system ---

Install the power centerplane and attach it with the cross-slotted shoulder standoff screws.
The power centerplane floats on the shoulder standoff until the four remaining screws secure it into position after the installation of the Sun Fireplane interconnect.
Securing of the ground screws at this time (after installation of the power centerplane and the cross-slotted shoulder screws) is not advised until after the installation of the Sun Fireplane interconnect.
Do not secure the ground screws at this time.

Verify the red wires are installed in the top row and the black wires are installed in the bottom row
Install the eighteen voltage-and-return DC power cables to the power centerplane.
Connect the P0.9 six-wire friction-fit 48V power connector of the power centerplane to J0.9 on the cable tie-down panel.
Connect the five (5) ribbon cable connectors to the power centerplane.
Install the DC cable cover and secure with nine (9) M4x8 Phillips screws.
Reinstall fan tray F3.
Install the Sun Fireplane interconnect assembly, if not previously installed.
Secure the power centerplane into position with the four panhead grounding screws to the power centerplane.
Install all system expander and the centerplane support board sets.

--- From the rear of the system ---

Install the seven cross-slotted standoff nuts onto the male threads of the cross-slotted shoulder standoff screws.
Connect the eighteen voltage-and-return AC power cables to the power centerplane.
Connect the P1.9 six-wire friction-fit 48V power connector at the power centerplane to J1.9 on the cable tie-down panel.
Connect the five (5) ribbon cable connectors to the power centerplane.
Install the DC cable cover and secure with nine (9) M4x8 Phillips screws.
Reinstall fan tray F7.
Install all system expander and the centerplane support board sets.

Power on the system controller
- - Connect the AC power cords and all I/O cables
- - Power on the AC0 and AC1 then both SCs will be booting up
Power on the domain(s)
sc% setkeyswitch -d domain_id on
