Caution – Before handling components, attach an ESD wrist strap to the grounding
post that is built into the rear of the chassis (see
FIGURE 1-3
for the location). The
system’s printed circuit boards and hard disk drives contain components that are
extremely sensitive to static electricity.
3. If the server is in a rack, slide it far enough from the rack so that you can
remove the cover. If you cannot safely view and access the motherboard,
remove the server from the rack.
4. Remove the top cover from the server.
See “Removing the Top Cover” on page 33 .
5. Remove the PCI tray.
See “Removing the PCI Tray and PCI-E Ribbon Cables” on page 34 .
6. Install the shorting jumper across the Clear CMOS header pins.
See
FIGURE 2-6
for the Clear CMOS jumper location at J9.
7. Wait 10 seconds, then remove the shorting jumper.
This jumper removes battery power from the SouthBridge chipset where the
CMOS settings are stored, thereby removing the CMOS settings.
8. Reinstall the cover to the server.
9. Reconnect AC or DC power cords to the server.
The server powers up to standby power mode, indicated when the Power/OK
LED on the front panel is flashing.
Using the Reset and NMI Switches
Caution – Do not use the Reset and NMI switches unless you are instructed to do
so by authorized Sun service personnel.
The Non-Maskable Interrupt (NMI) switch (SW3 on the motherboard) sends an NMI
order to the CPUs, which is used by Field Service for debugging activities at the
request of Service personnel. The button for this switch can be pushed by inserting a
paper clip or similar stylus through the hole provided on the rear of the chassis (see
FIGURE 2-7
, which shows the NMI Switch location on the Netra X4200 M2 server).
