1. Before Starting the Removal Work
NOTICE: During the removal work, the part statuses in the Web Console, Maintenance Utility,
and Maintenance Utility (Sub Panel) windows might be displayed di󰀨erently from
the actual statuses. (Example: The Drives during the removal are displayed as the
[Blocked] status.)
In that case, complete the running maintenance operation, and then refresh the
display information in each window.
If you make a mistake in the operation of the removal work, user data in the Storage System may be lost.
Therefore, perform the followings before starting the removal work to prepare against an unexpected
accident.
1. Back up user data.
Back up user data in the Storage System by the operation on the host computer side.
2. The removal operation varies depending on the component and the location where the component is
installed. Besides, remove an optional component after making sure whether the work must be done with
the Storage System power on or off.
• A removal with the Storage System power turned on :
A status in which the Storage System power is turned on regardless of whether the system (host
computer) is turned on or off.
• A removal with the Storage System power turned off :
A status in which the Storage System power is turned on regardless of whether the system (host
computer) is turned on or off.
3. When removing the optional component, it is required to change the settings of the Storage System using
a Maintenance PC connected via a LAN. Make the following preparations before starting to remove the
optional component.
• Ask the customer whether the Storage System is operable via a LAN. If not, obtain customerʼs
permission to operate the Storage System via a LAN.
4. Promote mutual understanding with the user about the possibility of a system down in order to minimize
damage caused by failures.

5. Be sure to install a dummy (Controller Board) and a dummy (Drive) in a free slot because dummy
(Controller Board) and dummy (Drive) are required for adjusting the cooling air flow.
When removing the optional component with the power on, the operation replacing Drive with dummy
(Drive) has to be finished within 10 minutes.
6. Do not remove the parts while the Storage System is being started.
When the Storage System is being started, remove the parts after the Storage System becomes the Ready
status.

NOTE: Turn on the LOCATE LED by using Maintenance Utility during maintenance work.
If you cannot turn on the LOCATE LED, check the number (*2) shown on the label
attached to the lower left part of the front side of FBX so that you do not confuse the
maintenance target.

NOTICE: To prevent part failures caused by static electrical charge built up on your own body,
be sure to wear a wrist strap connected to the Storage System before starting and
do not take it o󰀨 until you finish. See “Note when Installing and Removing Parts”
(INST(GE)01-01-10).

NOTICE: Check that the main edge connector of the Drive (HDD/SSD/SCM) has no
deformation, damage or sticking of dust before installing the Drive.

1. Removing Drives for SBX/NBX
(1) Detaching the Drive
NOTICE: Since the HDD is a precision component, handle it very carefully not to apply a
vibration or shock to it.
Pull the stopper of the handle toward you to unlock (), open the handle, and then remove the
Drive by pulling it out taking care not to apply a shock to it.
When using the removed Drive for the purpose of addition to another Storage System, keep it in
custody with its handle returned to its original state (locked by the stopper) taking care not to apply
a shock to it.

(2) Installing dummy (Drive)
NOTICE: Do not subject the drive to strong vibrations or shocks during handling due to the
precision part.
(a) Install the dummy (Drive) in the slot from which the Drive has been removed.
NOTE : Be sure to insert the dummy (Drive) in the free slot because it is necessary to regulate
a cooling air flow inside the Storage System.
(b) Insert it into the slot slowly so that the latch part of the dummy (Drive) comes to the lower
side.
