Configuring the <strong>Sidewinder</strong> <strong>G2</strong> to use a UPS<br />

Configuring the<br />

<strong>Sidewinder</strong> <strong>G2</strong> to<br />

use a UPS<br />

3-58 General System Tasks<br />

To enable the use <strong>of</strong> the second processor, perform the following<br />

steps.<br />

1. Enter the following command at a <strong>Sidewinder</strong> <strong>G2</strong> command line to<br />

switch to the Admn domain:<br />

srole<br />

2. Type one <strong>of</strong> the following commands to enable the multi-processor<br />

feature.<br />

If you want to test how multi-processor mode works on your<br />

system, but you do not want it enabled permanently, type the<br />

following command. You can skip step 4 if you use this command.<br />

cpu mp<br />

If you have tested multi-processor mode and are confident<br />

enough to enable it permanently, type:<br />

touch /etc/mp.config<br />

3. Reboot the <strong>Sidewinder</strong> <strong>G2</strong>.<br />

4. Check to see that the second CPU is active by typing the following<br />

command.<br />

cpu stat<br />

If you encounter a problem enabling the second processor, it might<br />

indicate that you need to modify the /etc/boot.default file or the<br />

/etc/mp.config file by adding the proper interrupts or command<br />

overrides for your specific hardware platform. Contact Secure<br />

Computing <strong>Technical</strong> Support if you have questions or problems.<br />

Once multi-processor mode is enabled, the only way to disable it is to<br />

delete the /etc/mp.config file and reboot the <strong>Sidewinder</strong> <strong>G2</strong>.<br />

Many organizations connect the <strong>Sidewinder</strong> <strong>G2</strong> to an Uninterruptible<br />

Power Supply (UPS). This allows the <strong>Sidewinder</strong> <strong>G2</strong> to continue to be<br />

operational if a power outage occurs. If the power outage is long<br />

enough, however, the battery in the UPS will begin to fail. To avoid an<br />

uncontrolled shutdown, you can configure the <strong>Sidewinder</strong> <strong>G2</strong> to<br />

initiate an orderly shutdown before the UPS fails. The <strong>Sidewinder</strong> <strong>G2</strong><br />

is much more likely to restart in a good condition following an orderly<br />

shutdown than from an uncontrolled shutdown.
