Hardware Appliances: Remotely Resetting Appliance Power 
If a hardware appliance requires a hard reset, you can reboot the appliance chassis remotely using a 
third-party Intelligent Platform Management Interface (IPMI) tool. 
Restrictions 
Remote power management is available only on certain hardware. For specifics, see Enabling 
Remote Power Management, page 21-4. 
If you want be able to use this feature, you must enable it in advance, before you need to use it. For 
details, see Enabling Remote Power Management, page 21-4. 
Only the following IPMI commands are supported: status, on, off, cycle, reset, diag, soft. Issuing 
unsupported commands will produce an “insufficient privileges” error. 
Before You Begin 
Obtain and set up a utility that can manage devices using IPMI version 2.0. 
Understand how to use the supported IPMI commands. See the documentation for your IPMI tool. 
Procedure
Step 1
Use IPMI to issue a supported power-cycling command to the IP address assigned to the Remote Power 
Management port, which you configured earlier, along with the required credentials. 
For example, from a UNIX-type machine with IPMI support, you might issue the command: 
ipmitool -I lan -H 192.0.2.1 -U remoteresetuser -P password chassis power reset 
where 192.0.2.1 is the IP address assigned to the Remote Power Management port and remoteresetuser 
and password are the credentials that you entered while enabling this feature. 
Step 2
Wait at least five minutes for the appliance to reboot. 
Site Access Problems

This is a partial list of applications cannot be used when the Web Security appliance is deployed in 
transparent mode because they do not support authentication.
