Chapter 2 Basic Operation
2.1 Powering On and Off
Before turning on the ETERNUS DX Disk storage system, make sure that the main line switches of the power
distribution units and the PSU switches on the power supply units of the ETERNUS DX Disk storage system are
"ON".
Do not turn the main line switches of the power distribution units and the PSU switches on the ETERNUS DX
Disk storage system to the OFF position.
• After turning the power on, it takes about two minutes for the ETERNUS DX Disk storage system to
become READY (i.e. the READY LED turns on). If an error is detected during the initial power-on diagnostic
phase, a longer time (up to ten minutes) may be required before the READY LED turns on.
• Before turning the server on, check that the ETERNUS DX Disk storage system and the network devices
that connect the ETERNUS DX Disk storage system and the server are all in READY status. If the server is
turned on while any of these devices are not in READY status, the server may not be able to recognize the
ETERNUS DX Disk storage system.
• When turning on the power in conjunction with the power synchronized unit, perform the appropriate
waiting process so that the ETERNUS DX Disk storage system is in the READY status before the server is
turned on. Since it takes up to ten minutes before the ETERNUS DX Disk storage system change to READY
status when an error is detected for a component during the initial power-on diagnostic phase, take this
into consideration and specify an appropriate waiting process that is sufficient.
• If the Auto Power function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX Disk storage
system is automatically turned on when power is supplied to the ETERNUS DX Disk storage system.
• If the Power Resume function is enabled via ETERNUS Web GUI or ETERNUS CLI, the ETERNUS DX Disk
storage system is automatically turned on after the power is restored.
This section explains how to use the Power switch to turn on the ETERNUS DX Disk storage system. For other
