Chapter 3 Powering On/Off Procedure
The disk drive may emit audible mechanical sounds when the disk drive is started (spun up),
immediately after the subsystem is powered on and powered off (spun down). However, this
does not indicate a problem if the WARNING or ALARM LED of the basic frame is off; you may
use the subsystem.
This section describes power on/off procedures for the following:
 AMS200 Rack-Mount Model
 AMS200 Floor Model
This chapter provides the information on the Fibre, NAS, and iSCSI models. The following
table illustrates the sections that provide the explanation for each model. According to the
customer 's model, please read the required section.
 Fibre model: Connects disk array subsystem to a host computer with Fibre Channel
interface.
 NAS model: Connects NAS Unit connected to disk array subsystem to a host computer
with LAN interface.
 iSCSI model: Connects disk array subsystem to a host computer with iSCSI interface.

If the array subsystem connected to the NAS Unit is restarted, the cluster between the NAS
Units stops. When the array subsystem is unavoidably restarted, execute it after stopping
the cluster between the NAS Units and stopping the NAS OS of both NAS Units. Start the
cluster between the NAS Units again after completing the restart for the array subsystem.
