6. Move the password override switch (switch 2) from its upward position to its lower position. 7. Replace any components that were removed. 8. Replace the cover. You will be able to start the server one time, without having to use the power-on password, and start the Configuration/Setup Utility program. You can either delete the old password or set a new power-on password. If you do not change or delete the password, the next time you start the server the original power-on password will be reinstated. 9. Connect the server to a power source, keyboard, monitor, and mouse. 10. Turn on the server. The Configuration/Setup Utility program starts. 11. Follow the instructions to erase the existing password or create a new password. 12. Select Save Settings and press Enter. When the password reset is completed, you must move the password reset switch back to its upward position. Updating Remote Supervisor Adapter II SlimLine firmware Information about updating the firmware of the Remote Supervisor Adapter II SlimLine can be found in the Remote Supervisor Adapter II User's Guide. Power checkout Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition. A general procedure for troubleshooting power problems is as follows: 1. Turn off the server and disconnect all ac power cords. 2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if there is a loose screw causing a short circuit on a circuit board. 3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until the server is at the minimum configuration required to start the server (see "Minimum operating requirements" on page 140). 4. Reconnect all ac power cords and turn on the server. If the server starts up successfully, replace adapters and devices one at a time until the problem is isolated. If the server does not start up from the minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated. To use this method, it is important to know the minimum configuration required for a system to start (see page 140). For specific problems, see "Power-supply LED errors" on page 116. 100 xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide

Power

Power
problems
can
be
difficult
to
solve.
For
example,
a
short
circuit
can
exist
anywhere
on
any
of
the
power
distribution
buses.
Usually
a
short
circuit
will
cause
the
power
subsystem
to
shut
down
because
of
an
overcurrent
condition.
A
general
procedure
for
troubleshooting
power
problems
is
as
follows:
1.
Turn
off
the
server
and
disconnect
all
ac
power
cords.
2.
Check
for
loose
cables
in
the
power
subsystem.
Also
check
for
short
circuits,
for
example,
if
there
is
a
loose
screw
causing
a
short
circuit
on
a
circuit
board.
3.
Remove
adapters
and
disconnect
the
cables
and
power
connectors
to
all
internal
and
external
devices
until
the
server
is
at
the
minimum
configuration
required
to
start
the
server
(see
“Minimum
operating
requirements”
on
page
140).
4.
Reconnect
all
ac
power
cords
and
turn
on
the
server.
If
the
server
starts
up
successfully,
replace
adapters
and
devices
one
at
a
time
until
the
problem
is
isolated.
If
the
server
does
not
start
up
from
the
minimal
configuration,
replace
FRUs
of
minimal
configuration
one
at
a
time
until
the
problem
is
isolated.
To
use
this
method,
it
is
important
to
know
the
minimum
configuration
required
for
a
system
to
start
(see
page
140).
For
specific
problems,
