PS6500 Hardware Maintenance Basic Array Information
Turning on Power to an Array
There are two power modes for a PS6500 array:
• Standby mode. An array enter s standby mode if you turn of f power, but two or more functioning power supply
and cooling modules are connected to a source of power. In standby mode, the array is fully grounded, and
some array components are supplied with power. For example, the power button is lit and the LCD panel
displays “standby.” However, disks and control modules are not supplied with power, and the array is not
operational.
• Full-power mode. An array enters full-power mode when you push the power button on an array that is
currently in standby mode. All components and modules are supplied with power and the array becomes
operational.
To turn on power completely and restart an array:
1. Make sure three power supply and cooling modules are installed, and make sure at least two modules are
connected to a source of power, ideally on different circuits.
2. Remove the bezel, as described in Removing and Installing the Bezel on page 1-8.
3. Press the blue power button on the front panel.
When the array restart completes, if the array is a member of a group, the LCD panel will show the member name.
Shutting Down and Turning Off Power to an Array
Although a PS Series array includes hot-swappable hardware components, in some cases, you must cleanly shut
down the array and turn off power in order to perform maintenance.
Notes: When you shut down an array that is a member of a group, any volumes with data on the array will be set
offline until the array is restarted. This may affect initiators that are connected to the volumes.
Turning off power to an array will clear any messages on the LCD panel. Record any information shown in
the panel before turning off power.
To shut down and turn off power to an array:
1. Use one of the following procedures:
• Use telnet or SSH to connect to an IP address assigned to a functioning network interface on the array. Do
not connect to the group IP address.
• Use the serial cable shipped with the array to connect the serial port on the active control module (the ACT
LED will be green) to a console or a computer running a terminal emulator.
