Step 4
Locate DIP switch block SW1 and the switch for pins 3 - 14 (see
Figure 57: Location of DIP Switches on Chassis
Motherboard, on page 119
).
Step 5
Move the DIP switch from position 3 to the closed, on position.
Step 6
Reinstall the top cover and reconnect AC power cords to the server. The server powers up to standby power mode,
indicated when the Power LED on the front panel is amber.
Step 7
Return the server to main power mode by pressing the Power button on the front panel. The server is in main power
mode when the Power LED is green.
You must allow the entire server to reboot to main power mode to complete the reset. The state of the jumper
cannot be determined without the host CPU running.
Note
Step 8
Press the Power button to shut down the server to standby power mode.
Step 9
Remove AC power cords from the server to remove all power.
Step 10
Remove the top cover from the server.
Step 11
Move the DIP switch back to its default, off position.
If you do not return the switch to the default, open position, the CMOS settings are reset to the defaults every
time you power-cycle the server.
Note
Step 12
Replace the top cover to the server.
Step 13
Reconnect power cords to all power supplies and then allow the server to boot to standby power mode.
Step 14
Fully power on the server to main power by pressing the Power button.
Using the Reset Cisco IMC Password to Default Switch (Positions 6 - 11)
You can use this Cisco IMC debug switch to force the Cisco IMC password back to the default.
Step 1
Shut down and remove power from the server as described in
Shutting Down and Removing Power From the Server,
on page 35
. Disconnect power cords from all power supplies.
Step 2
Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
If you cannot safely view and access the component, remove the server from the rack.
Caution
Step 3
Remove the top cover from the server as described in
Removing the Server Top Cover, on page 37
.
Step 4
Locate DIP switch block SW1 and the switch for pins 6 - 11 (see
Figure 57: Location of DIP Switches on Chassis
Motherboard, on page 119
).
Step 5
Move the DIP switch from position 6 to the closed, on position.
Step 6
Reinstall the top cover and reconnect AC power cords to the server. The server powers up to standby power mode,
indicated when the Power LED on the front panel is amber.
You do not have to return the server to main power for the change to take effect. Only Cisco IMC (the BMC) must
reboot. The change takes effect after Cisco IMC finishes booting.
When you next log in to Cisco IMC, you see a message similar to the following:
'Reset to default CIMC password' debug functionality is enabled.
On input power cycle, CIMC password will be reset to defaults.
