PS6610 Hardware Owner's Manual
Enable 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 groupwide; that is, it allows you to press the button to shut down
any member (array) that has the standby button (PS4100, PS4110, PS6100, PS6110, PS6210, and
PS6610 array models). 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.
Use the Standby On/Off Button
After the feature is enabled groupwide, 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.
• To shut down the member to the standby state, press in and hold the Standby On/Off button for at
least two (2) seconds.
• To fully shut down the array, turn off the switches on the power supplies.
• To turn the member back on, press and hold the Standby On/Off button again (and ensure the
power supply switches are turned back to the on position).
Important Considerations
Use the Standby On/Off button only when you must shut down a member quickly, in situations where
you do not have access to the Group Manager GUI or CLI. For example, you discover a problem in
your lab environment, such as high temperature or a water leak, that might damage the array.
Caution: In standby mode, all volumes that use space on that member or that are bound to that
member become unavailable. All operations on the member are suspended, no I/O activity to or from
the member occurs, and the member's firmware is not running.
Caution: When replacing a failed control module, do not shut down the array with the standby on/off
button or by any other method. If the member is shut down, the array automatically returns to full-
power mode when a control module is inserted.
