Turning on the server
Notes:
1. Pressing the power-control button on either the primary or secondary server in
the 16-way configuration (models 1VX, 2VX, 3VX only) will turn on or turn off
both servers.
2. When turning on a 16-way configuration server (models 1VX, 2VX, 3VX only), in
some instances the system error LED will light (see “Front view” on page 7),
indicating that only 12 microprocessors are being detected. If this happens, take
the following actions:
a. Open the light path diagnostics panel (see “Light path diagnostics” on page
54) and verify that the Event Log LED is illuminated.
b. Check the system error log (see “Viewing the System Error log” on page 60)
for these two messages:
v
″
PFA Alert, see preceding error in system error log
″
v
″
Upper to lower SMP Expansion Module cable not detected
″
c. Clear the error log, turn off the servers, remove ac power for 30 seconds,
reconnect ac power, and restart the servers.
d. If the symptoms repeat, verify that all cables are connected correctly (see
“Working with cables” on page 115); then, repeat steps 2a through 2c
above.
e. If the symptoms persist, run diagnostics (see “Starting the diagnostic
programs” on page 59) and follow the recommended actions.
You can turn on the server in any of the following ways:
v
If the power cords are connected to a power source, you can press the
power-control button on the front of the server.
Notes:
1. You can install a circular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with the server.
2. After you plug the power cords of the server into the electrical outlets, wait
approximately 20 seconds before pressing the power-control button. During
