This chapter contains the procedures for installing or replacing SIMMs and
NVSIMMs in the SPARCserver 1000 system.
To halt the system safely:
1. Back up the system files and data, if necessary.
2. Notify users that the system is going down.
3. Halt the system using the appropriate commands.
4. Wait for the system-halted message and the boot monitor prompt.
5. Turn the key switch located on the front panel of the server to the
Standby position.
6. Turn the AC power switch on the system back panel off.
Caution -
The system chassis power must be turned off, and the AC power
cord must remain plugged in to ensure a proper ground.
Caution -
Use a cushioned ESD mat for these procedures. There are breakable
parts on the bottom of the system board.
1. Unfasten any cable connectors from the board back panel and set them
aside.
First disconnect any keyboard, SCSI, network, or other cables connected to
the back panel. Label any cables that are similar in appearance, to avoid
confusion later.
2. Remove the two screws that hold the system board to the card cage.
See Figure 2-1. Set the screws aside for later reinstallation.

3. Pull the curved ends of both extraction levers outward simultaneously to
release the board from the backplane connectors.
See Figure 2-2.

Removing the System Board
4. Holding the board by both of the extraction levers, gently slide the board
out of the card cage.
Caution -
The board has a cutout on the right-hand side, therefore, the right
side of the board will clear the card guides before the left side. Grip the edges
of the board firmly or the board could fall and damage components.
5. Place the board on a cushioned ESD mat.
Be careful not to flex the board while moving it.
If replacing faulty SIMMs, refer to the location numbers (also known as
J-numbers or U-numbers) shown in Figure 2-3.
If upgrading memory, install sets of SIMMs or NVSIMMs as full groups of
four. When upgrading more than one board, start with bank 0 on the lowest-
numbered board. Distribute SIMM sets in all group 0 locations before filling
group 1 locations.

SIMM Socket Locations on the SPARCserver 1000 Board
To remove a SIMM from a system board:
1. Locate the faulty SIMM by matching the location number displayed by
POST with the J-number shown in Figure 2-3.
2. Orient the system board so that the backplane connector faces you.
3. To unlock a SIMM, press the locking tabs toward the outside of the socket
and tilt the SIMM forward.
See Figure 2-4.

Unlocking a SIMM
4. Unlock two more SIMMs to make space for the faulty SIMM to tilt
forward far enough to be free of the locking pins.
See Figure 2-5.

5. For NVSIMM only:
-
To save data stored in the NVSIMM, do not move the battery jumper.
-
If the data is not worth saving, conserve battery power by moving the
battery jumper to the OFF position shown in Figure 2-6.

NVSIMM Jumper Location
6. Store or ship the SIMM or NVSIMM in an antistatic bag.
Note -
Do not mix SIMMs of different capacities in the same bank.
1. Orient the system board so that the XDBus connectors face you.
2. Remove the SIMM (or NVSIMM) from the antistatic package.
3. For NVSIMM only: if the battery is not already activated, move the
jumper to the ON position. See Figure 2-6. If the jumper is already in the
ON position, do not move it.
Caution -
Never move the jumper after the battery has been turned on, or data
contained in the NVSIMM will be lost.
4. Hold the SIMM at the edges, with pin 1 to your left.
The large alignment notch (see Figure 1-1) is at the left side.
5. Guide the SIMM into the slot so that the SIMM connector pads touch the
bottom of the socket.
Align the bottom alignment notch on the SIMM with the tab in the center of
the socket. The locking pins (see Figure 2-4) must align with the holes in the
sides of the SIMM.
6. Tilt the SIMM upright to lock it in place.
The locking tabs should automatically lock around the SIMM.
Note -
The SIMM should require very little insertion force. If there are
difficulties, the replacement SIMM may be backward. The alignment holes and
the alignment notch must align exactly with corresponding parts of the socket.
7. Lock back into place any SIMMs that were loosened in the SIMM
removal steps.
1. Carefully insert the board in the proper slot in the card cage, ensuring
that the board does not slip out of the left and right card guides.
The component side of the board must face up.
2. Ensure that the extraction levers are in the outward position as you slide
the board toward the backplane connectors.
See Figure 2-2. The board will not seat fully unless the levers are in this
starting position.
Caution -
DO NOT FORCE any board into a slot, this can cause damage to the
board and system. The board should insert and seat smoothly. If it binds,
remove it, and inspect the card cage slot for any obvious obstructions. Also
inspect both the board and the backplane for bent pins or other damage.
3. Use the extraction levers to seat the board.
Swing both extraction levers simultaneously into the locked position. Do not
press on board to seat it - doing so will damage the connector pins.
4. Install two screws to secure the board to the card cage.
See Figure 2-1.
5. Connect any applicable interface cables to the system board back panel.
To verify that the hardware was installed properly, run the POST program.
1. Turn on power to the monitor.
If the system does not have a monitor, connect an TTY terminal to serial port
A on the system master board and configure the terminal software. Refer to
the instruction manual shipped with the terminal for configuration
instructions.
The most commonly-used set-up is:
Note -
The parameters listed above may differ from the customer site settings.
See the set-defaults and printenv commands in the manual, OpenBoot
Command Reference.
2. Turn the server front panel key switch to 1 in order to boot the system and
run normal system diagnostics.
Watch the diagnostics display for error messages. POST should finish in
approximately 60 seconds.
3. Watch the boot display to confirm that the system memory total includes
the newly installed memory modules.
4. After the system finishes booting, log in and resume normal operation.
