Enabling the Standby Feature
To use the standby button, a group administrator must enable the feature in the Group Manager GUI or CLI.
Enabling the use of the button applies group-wide; that is, it allows you to press the button to shut down any
member (array) that has the button (currently PS4100, PS4110, PS6100, and PS6110 array models only). You do
not need to enable use of the button on each member separately.
Note: Only a user with group administrator privileges can enable the standby feature on the group. However,
anyone can press the button, and the group cannot determine who put the array into standby on/off mode.
Therefore, group administrators should consider their environment's security concerns before enabling this
feature.
Using the Standby Button
After the feature is enabled group-wide, you can use the Standby On/Off button on either control module of any
applicable member to shut down the array quickly without using the Group Manager GUI or CLI.
You must press in and hold the Standby On/Off button for at least two (2) seconds to shut down the member to
the standby state.
(To fully shut down the array, turn off the switches on the power supply and cooling modules.)
To turn the member back on, press and hold the Standby On/Off button again (if the power supply switches are
turned on).
