Managing the System Remotely B-11
Uses of the Switchpack
You can use the RCM switchpack to change the RCM operating mode or disable the
RCM altogether. The following are conditions when you might want to change the
factory settings.
•
Switch 1 (EN RCM)—Set this switch to OFF (disable) if you want to reset the
baud rate of the COM1 port to a value other than the system default of 9600.
You must disable RCM to select a baud rate other than 9600.
•
Switch 2 (Reserved)—Reserved.
•
Switch 3 (RPD DIS). Set this switch to ON (disable) if you want to disable the
poweroff command. With poweroff disabled, the monitored system cannot be
powered down from the RCM.
•
Switch 4 (SET DEF). Set this switch to ON (enable) if you want to reset the
RCM to the factory settings. See the section “Resetting the RCM to Factory
Defaults.”
Changing a Switch Setting
The RCM switches are numbered on the server feature module. The default
positions are shown in Figure B-2. To change a switch setting:
1. Turn off the system.
2. Unplug the AC power cords.
NOTE: If you do not unplug the power cords, the new setting will not take effect
when you power up the system.
3. Remove the system covers. See Section 4.3.
4. Locate the RCM switchpack on the server feature module and change the switch
setting as desired.
5. Replace the system covers and plug in the power cords.
6. Power up the system to the SRM console prompt and type the escape sequence
to enter RCM command mode, if desired.
