BeforeYouStart
This manual provides procedures for installing a power supply in a redundantcapable SPARCcenter 2000 or 2000E system cabinet.
1.1 Safety Precautions
For your protection, observe the following safety precautions when setting up
your equipment:
• Follow all cautions, warnings, and instructions marked on the equipment.
• Ensure that the voltage and frequency rating of the power outlet you use
• Use properly grounded power outlets only.
• Never push objects of any kind through openings in the equipment as they
• Refer servicing of equipment to qualified personnel.

may touch dangerous voltage points or short out components that could
result in fire or electric shock.

To protect both yourself and the equipment, observe the following precautions:
Table 1-1 Safety Precautions
Item Problem Precaution
Springfingers Personal injury The springfingers have sharp edges. Use care when handling springfinger-
equipped cabinet screens and system boards.
RFI leakage Keep springfinger-equipped screens and panels in place when the system is
running. These assemblies suppress radio frequency interference (RFI) and
are required by law in many localities.
Damaged

with a wrist strap or foot strap. The mat also cushions and protects small
parts that are attached to printed circuit boards.
Attach all cabinet cover panels after performing service work on the system.
Install card cage filler panels in all unused card cage slots. Open slots
severely reduce the cooling capability of the system.
Install SBus slot covers in all unused system board SBus slots. Openings on
the backs of system boards reduce the cooling capability of the system.

2.1 Operating System
The correct operating system must be installed to support dual power supply
operation. The operating system must be:
Solaris 2.4 or higher, or
Solaris 2.3 with the patch: ID# 101318-59 or later revision level (obtain this
patch through your normal service channels)
Check to see which operating system is running on your machine. If necessary,
load one of the correct Solaris versions listed here before proceeding.
2.2 Open Boot PROM
The system boards require the Open Boot PROM version -10 or higher to
support dual power supply operation. If necessary, install new PROMs on all
system boards before proceeding.
2.3 Powering Down the System
Halt the operating system before turning off system power. Proceed below.
1. Notify users that the system is going down.
2. Be sure that the system files and data have been backed up.
3. Halt the system using the appropriate commands.
The halt procedure varies for different types of operating systems. Refer to
the documentation for your operating system for the correct halt procedure.
4. Wait for the system-halted message and the boot monitor prompt.
5. Turn the key switch to the (standby) position.
See Figure 2-1.
6. Turn AC power off:
Turn the AC distribution unit power switch to Off. The switch is at the rear
of the cabinet. See Figure 2-2.

2.4 Access
Remove all system cover panels before proceeding with the upgrade. For these
procedures, refer to Appendix A, “Access.”
2.5 Installing the Bottom Power Supply
Note – Read and follow all safety and ESD instructions found in Section 1.1,
“Safety Precautions.”
2.5.1 Identifying a Redundant-Capable Cabinet
Note – The cabinet in question is a redundant-capable cabinet if:
• The power supply cover panel on this chassis is long as shown in Figure 2-3.
This panel reaches to the bottom of the frame. In contrast, the cover panel on
the non redundant-capable chassis reaches about half the way down the frame
• The cabinet is configured with the power supply adapter board. This board,
if present, can be viewed by looking through the EMI screen on the front of the
system.

2.5.2.6 Power Supply Sense Cable
1. Remove the jumper-connector from the power supply adapter board.
You will find this device plugged into the connector nearest the outside
edge of the cabinet. Remove it. See Figure 2-18.
2. Plug the sense cable for the bottom power supply into the power supply
adapter board.
Plug it into the near-most connector — from which the jumper-connector
was removed in Step 2.
3. Plug the other end of the sense cable into the sense connector on the
bottom power supply.
Plug it into J1 near the top of the supply.
Jumper connector: Remove to allow the

2.6 Restarting the System
Note – As the system starts up, watch for error messages from the POST
diagnostic program. If a terminal is not already part of the system, install a
TTY terminal before continuing the start up. See the SPARCcenter 2000
Installation manual for terminal settings.
1. The system key switch must be turned to (the standby position).
See Figure 2-1.
Caution – The outlet must be a 200-240 Vac 30-ampere circuit, intended solely
!
for use by the server cabinet, as described in the site preparation instructions in
the SPARCcenter 2000 Installation manual. The electrical receptacle must be
grounded, and the grounding conductor serving this receptacle must be
connected to the earth ground at the service equipment.
2. Turn the Local/Remote switch down, to Local. See Figure 2-20.
3. Turn on the power switch on the AC distribution unit.
See Figure 2-2.
4. Turn on power to the terminal.
A terminal is required for viewing system messages.
5. Turn the key switch to (the power-on position). See Figure 2-1.
Several things will happen:
• The DC-powered blower fan in the top of the cabinet begins turning.
• The left front panel LED (green) turns on immediately to indicate the DC
power supply is functioning.
• The middle front panel LED (yellow) lights immediately and should turn
off after approximately 60 seconds.
• The right front panel LED (green) lights after POST has ended to show
that booting is successful.
• The terminal beep indicates that the system is ready.
• The terminal screen lights up upon completion of the internal self test.

Caution – Never move the system cabinet or the expansion cabinets when

system power is on. Excessive movement can cause catastrophic disk drive
failure. Always power the system OFF before moving cabinets.

6. Watch the terminal screen for any POST error messages.
At the conclusion of testing, POST automatically configures the system,
omitting any devices that have failed diagnostics. After POST ends, the
system will boot using the new configuration.
If the middle front panel LED remains lit after the system has booted, the
system has failed POST.
If you system has two power supplies and one fails, the system will
continue to operate. If POST, OBP or the operating system detects the power
supply failure, a warning message similar to the one below will be
displayed to the console:
Power supply maintenance should be scheduled.
Note – POST does not test drives or internal parts of SBus cards. To test these
devices, run OpenBoot PROM (OBP) diagnostics manually after the system has
booted. Refer to the OpenBoot Command Reference manual for instructions.
7. To start POST again, or if the system hangs, press the reset switch on the
back of the front panel.
See Figure 2-21.

8. If the system displays “not responding” or “no carrier” messages, the
Link Integrity Test may be set incorrectly.
2.7 Reading Boot Messages
Use the boot software messages to verify the presence of options in the system.
After POST completes the system self-test, a message similar to the following
will appear on your screen. The message lists hardware detected in the system.

Note – The following screen display is an example only. The actual message
displayed on the screen will vary with the software running on the system.

Note – When a system is started for the first time, or if the master board is
replaced, OBP will prompt you to select a system board to be the new system
master. The system master is normally in slot 0.
If there is no terminal on this system, you must check the system status by
inspecting LEDs on the front panel and if present) on the power supply
adapter board. See Figure 2-22 and Figure 2-23.
Table 2-1 summarizes LED status conditions during and after POST.
