2. On the CBSL or CBSS, press the main switch on either Controller #0 or
Controller #1 for three seconds or more using a pen or similar object.
The CBSS/CBSL green C-PWR LED blinks for three seconds and then
goes ON.
3. If a DBW is connected to the CBSL or CBSS, turn off the Power Switch.
However, if the power interlock mode is set to the UPS interlock mode1/
2/3, remove the UPS interlock cable connected to the CBSL/CBSS, and
then turn off the main switch.
NOTE: When you remove the UPS interlock cable, an email alert
notification is sent (if configured in Hitachi Storage Navigator Modular 2)
and a TRAP is received by the SNMP Agent Support Function.
4. Confirm that the POWER LED on the front of the storage system
changes from green to orange (this should take approximately 10
minutes).
-
The green READY LED on the DBL/DBS/DBX does not go OFF
when the main switch is turned off in the Maintenance mode. This
is normal and does not indicate a problem.
-
The green ACT LED on a drive might continue to blink after the
orange POWER LED goes ON. This is normal and does not indicate
a problem.
5. Power off the storage system as follows:
-
If the storage system power cables are connected to a PDB, check
whether other devices, such as switches, are also connected to the
PDB.
If the storage system is the only device connected to the PDB, power
off the circuit breakers of the PDB.
If other devices are connected to the PDB, check whether they can
be powered off. If they cannot be powered off, remove two power
cables (four power cables for DBX) from the power units of the
Controller Box and Drive Box.
-
If the power cables are connected to something other than a PDB,
remove two power cables (four power cables for DBX) of the
Controller Box and Drive Box, or turn off the input power.
6. Remove all Fibre Channel and iSCSI cables from the rear of the CBSL/
CBSS. Leave the other end of the cables connected to their respective
devices.
Removing power cables
After you shut down the storage system, remove the power cables from the
Hitachi Unified Storage 130.
1. Remove the Hitachi Unified Storage 130 front bezel (see
replacing the front bezel on page
2. Remove all power cables from the Hitachi Unified Storage 130.
