Installation and Operations Manual
Setting the Sentry Power Manager (SPM) options:
The Sentry Power Manager (SPM) is Server Technology’s enterprise management software product for
the data center. The configuration options provided allow you to enable/disable SPM and reset the SPM
password to its default.
NOTE: The SPM options only apply if you are currently using Server Technology’s SPM software. In addition, the SPM
options are only available on the HTTP/SSL web page. There are no equivalent SPM options on the Command Line
Interface (CLI).
SPM Secure Access:
If your operation does not currently use SPM software, you can disable SPM Secure Access. However,
if disabled, the PT22 will not be able to use the SPM suite of secure network capabilities or the
advanced remote configuration.
Select Enabled or Disabled from the SPM Secure Access drop-down menu and click Apply.
NOTE: Both HTTP and SSL must be enabled or the SPM Secure Access option will not be permitted. When SPM Secure
Access is permitted, the default is Enabled.
SPM Password:
Each PT22 has a default unique SPM password that is used to communicate between SPM and the
PT22. When SPM discovers a unit in the network, SPM changes this password into a different unique
password for added security. The SPM then continues to manage or alter these passwords as required
for system security.
If a unit is relocated or swapped from the system after a password was generated, the SPM may not be
able to reestablish a connection to the unit. The SPM Password checkbox allows you to reset this back
to the internal default password of the PT22 so the SPM can re-discover the device and add it to the
system. Once the unit has been acquired by SPM, no further action is necessary.
To reset the password, check SPM Password and click Apply.
NOTE: Do not reset the password if SPM communication has already been established.
