Notes on Use  
The following includes information necessary for proper and safe operation of the  
additional disk enclosure.  
WARNING  
Do not use the additional disk enclosure in an area with much moisture or water  
usage. If so, a fault, electrical shock, or fire may occur.  
Do not use the additional disk enclosure in an area where inflammable gas and/or  
combustible substance are placed. If so, fire or explosion may occur.  
Do not concentrate power cords only to some AC outlets. If so, fire may occur.  
Do not put a heavy substance on a power cord. If so, the coating of the power  
cord may be broken, fire may occur, and/or you may be electrically shocked.  
Do not install the additional disk enclosure in an area of much moisture or dust.  
Remove dust adhering to AC outlets and the plugs of power cords, if any. If dust  
remains adhering to an AC outlet and/or plug, fire may occur.  
Do not connect the plug of a power cord to an AC outlet with a wet hand. If so, you  
may be electrically shocked.  
While the additional disk enclosure can accept the power of 100 - 240 VAC (50/60  
Hz), the power cord coming with the additional disk enclosure can only accept 100  
- 120 VAC. Use 100 - 120 VAC (50/60 Hz) when the attached power cord is used.  
Using power of different voltage may cause electric shock, smoke, and/or fire to  
occur.

CAUTION  
Do not install the additional disk enclosure and disk array unit on an unstable place.  
If so, some substances may be dropped to cause you to be injured.  
Do not install the additional disk enclosure and the power cords in an area with  
direct sunshine or near an apparatus generating heat such as a heater. If so, a fault  
may occur. Further, the coating of the power cord may be melted to cause fire or  
electric shock to occur.  
Insert the plug of a power cord to an AC outlet securely. Any power cord shall be  
routed with sufficient margin to avoid excess force from being given to the plugs of  
the power cord or the power cord itself. If a power cord is removed from the AC  
outlet during operation, data may be lost and/or a fault may occur.  
To prevent electric shocks, connect a power cord to an AC outlet with earth  
terminal. Connection of the earth line to a gas tube is extremely dangerous. Never  
do it.  
Connect or remove a peripheral from the additional disk enclosure after turning off  
all the powers of the additional disk enclosure and peripherals and pulling out the  
power cords from the AC outlets. If not, some units may be broken and/or you may  
be electrically shocked.  
To carry or reinstall the additional disk enclosure, disconnect all cables and power  
cords connected to the additional disk enclosure beforehand.  
If not, a malfunction of the system, an electric shock and/or fire may occur.  
To install the unit in a rack, observe the following guidelines.  
1. TMRA – If installed in a rack, consideration should be given to installing the  
equipment in an environment compatible with the TMRA.  
2. Reduced Air Flow – Installation in a rack should be such that the amount of air flow  
required for safe operation of the equipment is not compromised.  
3. Mechanical loading – Mounting of the equipment in the rack should be such that a  
hazardous condition is not achieved due to uneven mechanical loading.  
4. Circuit Overloading – Consideration should be given to the connection of the  
equipment to the supply circuit and the effect that overloading the circuits might  
have on overcurrent protection and supply wiring. Appropriate consideration of  
equipment nameplate ratings should be used when addressing this concern.  
5. Reliable Earthing – Reliable earthing of rack-mounted equipment should be  
maintained. Particular attention should be given to supply connections other than  
direct connections to the branch circuit (e.g., use of power strips).

2. FEATURES OF ADDITIONAL DISK ENCLOSURE  
The additional disk enclosure has the following features.  
NF2300-SE41E is a high-performance additional disk enclosure developed for the  
NF2300-SR4xxE disk array unit connected to the NEC Express5800 basic processing  
unit, NX7000 basic processing unit, or CX5000 basic processing unit.  
The additional disk enclosure NF2300-SE41E is not equipped with disk drives at the  
shipment. To use the additional disk enclosure, add disk drives sold separately.  
Up to 15 disk drives can be installed in NF2300-SE41E.  
The disk drives for disk array unit NF2300-SR4xxE can be added by connecting the  
additional disk enclosure NF2300-SE41E (up to 13 disk enclosures, 210 disk drives).  
The combination of the additional disk enclosure and disk array unit NF2300-SR4xxE  
enables a defected disk drive to be replaced with a new one without system shutdown.  
Further, the additional disk enclosure has the auto rebuild feature which automatically  
starts data recovery after the replacement of the defected disk drive.  
If a single disk drive is specified as the spare disk, the data in the defected disk drive can  
be immediately recovered in the spare disk. The use of this hot spare feature as well as the  
auto rebuild feature allows the data in the defected drive to be automatically recovered in  
the spare disk as soon as a disk drive is defected. This improves the system reliability.  
Refer to "NF2300-SR4xxE Disk Array Unit User's Guide" for details of hot spare feature.  
Further, owing to the redundant configuration of the adapter and power supply, the entire  
system is not shut down if any part of the system is defected during operation.  
See Section 9.2 "Optional Components" for the product names and part numbers of  
options.

5. CONNECTION OF ADDITIONAL DISK ENCLOSURE  
The user may conduct the connection of the additional disk enclosure  
described in this chapter. However, if so, NEC does not assume the  
responsibility for any damage of the additional disk enclosure and  
components and any influence resulting from the operation of the additional  
disk enclosure. NEC recommends that you ask your maintenance engineer of  
the maintenance service agent with expert knowledge on details of the  
additional disk enclosure to install or remove the additional disk enclosure.  
This chapter describes the basic procedure for connecting the additional disk enclosure to  
the disk array unit (NEC Storage S2300, 1/2 and 2/2). In the connection, also read the  
User's Guide of the disk array unit to which the additional disk enclosure is connected.  
CAUTION  
To connect a peripheral device to the additional disk enclosure, disconnect  
the power cord of the peripheral from the AC outlet. If not, you may be  
electrically shocked.  
Any FC cable and DE diagnosis cable used for the connection of the  
additional disk enclosure shall be approved by NEC. Also, the length of  
the cable shall be within the rating range. If an FC cable not approved by  
NEC is used or the length of the cable is out of the rating range, read data  
may be incorrect or invalid data may be written.  
To avoid incorrect wiring, make sure that connectors are connected to the  
proper destinations based on the cable specification.  
Do not push any cable connector excessively. Each connector can be  
connected properly only when it is inserted to the mating connector in the  
correct direction and at the correct angle. Proper insertion allows the  
connector to be inserted to the mating connector smoothly without excess  
force. If the connector cannot be inserted smoothly, do not insert it by  
force but check the direction of the connector again.  
Make sure that damages such as buckling, dust adhesion, and dirt are not  
found on the connector and contact before connection.  
Treat any connector carefully so that it may not be dropped on the floor to  
be damaged. Do not drag any connector on the floor to have dust adhere  
to the connector.  
Do not give excess force to the connector and cable connected with each  
other. Do not step or put a substance on a cable to deform the cable.  
Be sure to install disk drives into PD00 and PD01 of an additional disk  
enclosure.

When you change a failing disk to a spare disk, confirm the following to get  
the spare disk to function normally:  
The capacity of the spare disk is equal to or greater than that of the failing  
disk.  
The rotational speed of the spare disk is equal to or faster than that of the  
failing disk.  
Therefore, if a large-capacity disk is defined as a spare disk, it can cover all  
the disks of a high-speed drive. However, if your disk array unit contains disks  
of different capacities or different rotational speeds, you should define a spare  
disk matching the capacity and rotational speed of each disk in order to clarify  
disk management.  
Up to 2 spare disks can be installed for each disk enclosure. Up to 16 spare  
disks can be installed for the entire disk array unit.  
<Installation procedure>  
Disk drives may be installed in the additional disk enclosure with the powers of the  
additional disk enclosure, disk array unit, and host unit being ON.  
For the replacement of one or more dummy trays and disk drives, replace them one by  
one. Do not remove two or more dummy trays at a time.  
(1) Putting of location label  
Before installing the disk drive, select the location label appropriate to the location  
where the disk enclosure is to be installed, and put it on the additional disk drive.

(2) Removal of dummy tray  
Pull the ejector on the dummy tray toward you to release the lock. A click occurs  
when the lock is released.  
If the lock is released, hold the handle and pull out the dummy tray.  
Be sure to keep removed dummy trays in the designated place.  
After removing an additional disk drive from the unit, be sure to install a  
dummy tray into the slot. If using the unit without a dummy tray being  
installed, cooling effect on the disk drives lowers and causes heat  
generation. Heat generation increases the failure rate, and at its worst it  
may cause data loss.

7. HANDLING OF ADDITIONAL DISK ENCLOSURE  
This chapter describes how to handle the additional disk enclosure.  
7.1 Notes on Handling of Additional Disk Enclosure  
Note the following in use of the additional disk enclosure. Invalid handling of the  
additional disk enclosure may cause it to be defected and/or some data to be broken.  
If the HDD READY LED (green) blinks, the disk access operation is  
indicated on the host system, or the initialization is being operated, do not  
turn on/off the powers of the additional disk enclosure. Do not reset the  
host system.  
If the HDD READY LED (green) is lit or blinks and the disk access  
operation is indicated on the host system, do not give vibrations and  
shocks to the additional disk enclosure.  
Because the additional disk enclosure is a precision device, it shall not be  
subject to hard vibration or shock.  
The features of the additional disk enclosure are effective only for the  
hardware failure (e.g., the hard disk is physically damaged or inoperative).  
The software failure (e.g., the data is lost or rewritten due to program  
excursion) is not covered by these features. When the software failure would  
occur, the system could seriously be damaged. To minimize the damage, be  
sure to back up the data periodically.  
It is recommended that important files are backed up to magnetic tapes. This  
enables the damage to be minimized in case of emergency including sudden  
vibration or shock and power shutdown caused by power interruption.

7.2 Power On/Off of Additional Disk Enclosure  
This section describes how to turn on or off the power of the additional disk enclosure.  
Turning on or off the power carelessly may cause some data to be broken, some software  
to operate incorrectly, and/or the device to be defected.  
(1) AC power-on  
a) Before turning on the AC power, check for loose disk drives by pushing each  
disk drive.  
b) Turn on all the disk enclosures connected with the array controller, and then  
turn on the array controller. Alternatively, turn on the array controller and all  
the disk enclosures connected with the array controller at the same time.  
The additional disk enclosure has the redundant power configuration to prevent  
the entire unit from shutting down due to a single failure. Therefore, when  
turning on the disk enclosure, turn on all the power switches (of the array  
controller and disk enclosures) at the rear of the unit.  
When turning on the power switches, confirm that the POWER GOOD LED  
(green) of the power supply and the POWER LED (green) on the front panel of  
the unit go on. Power supply starts, and the POWER LED (green) is on while  
the power switches are on.  
The additional disk enclosure performs the self-test and initialization  
immediately after the power is turned on. When the self-test and initialization  
terminate and the disk enclosure becomes ready, the READY LED of the  
adapter stops flashing and enters the on state. The READY LED of the  
controller installed on the disk array unit also stops flashing and enters the on  
state.  
The additional disk enclosure (including the connected disk array unit) takes  
four minutes (at maximum) to start.

[Power-on procedure]  
Turn on the power switches in the following order (1) to (3):  
(3) Host system  
(1) Power switches of disk enclosures  
(2) Power switches of array controller  
(May be turned on at the same time the power switches of disk enclosures are turned on.)  
- 34 -

(2) Notes on turning off AC power  
The disk array unit to be connected with the additional disk enclosure periodically  
writes data from the cache memory onto a disk. If you turn off the AC power  
before completion of write to the disk, the remaining data on the disk is backed up  
by the battery backup units.  
However, the backup time is limited (4 days if the cache memory has the allowable  
maximum capacity and the two battery backup units are fully charged). To  
securely protect data, turn off the AC power after all the data has been written from  
the cache memory in the disk array unit onto the disk. Turn off the AC power  
according to the procedure explained in "(3) Turning off AC power".  
1. Turn off the host system and the host bus adapter or the FC-AL switch.  
Alternatively, offline all the buses connected to the host system that is  
connected with the disk array unit.  
2. If NEC Storage DynamicDataReplication is used, execute the Unpair  
command.  
3. Turn on the shut down switch (toggle switch with SHUT DOWN indicated) of  
the LAN card in the array controller. (*1)  
4. Confirm that [SDN LED] of the LAN card in the array controller is on, and  
then turn off the AC power according to the procedure explained in "(3)  
Turning off AC power".  
[SDN LED] flashes while data remaining in cache memory is being written  
onto the disk drive. Do not turn off the AC power while it is flashing. (*2)  
Relationship between [SDN LED] states and operations of the disk array unit:  
Normal state:  
Off  
During cache data write onto disk:  
Flashing  
Completion of cache data write onto disk: On  
Writing cache data onto a disk drive usually takes about 10 minutes and 20  
minutes at maximum.  
If cache data is not written onto a disk drive normally, the LEDs of the LAN  
card enters the following states. In this case, contact your maintenance  
service agent.  
RDY LED: On  
FLT LED: Flashing  
SDN LED: Off  
5. Turn off the shut down switch (toggle switch with SHUT DOWN indicated) of  
the LAN card in the array controller. (*3)  
- 35 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
*1 – The shut down switch has a locking mechanism. To turn on/off the switch, hold  
and raise the lever.  
– While the shut down switch is on, the disk array unit does not accept any I/O  
operation by the host system.  
(The Link UP LEDs of the controller's HL0 and HL1 go off.)  
*2 – If you turn off the AC power of the disk array unit during write operation (with  
SDN LED flashing) by mistake, the backup mode is enabled. (In this case, the  
controller's [BAT LED] goes on.)  
– If you turn off the AC power of the disk array unit during write operation (with  
SDN LED flashing) by mistake, turn on the AC power of the entire disk array  
unit (including the power of the additional disk enclosure) again. When the disk  
array unit has started (when the READY LED of the controller on the array  
controller stops flashing and enters the on state), turn off the shut down switch  
and then turn it on to complete the write operation.  
– Even if you turn off the AC power after [SDN LED] goes on, [BAT LED] goes  
on in the following case:  
NEC Storage DynamicDataReplication is used, but you attempt to write the  
remaining cache data before executing the Unpair command.  
In the above case, turn on the AC power of the entire disk array unit again.  
When the disk array unit has started (when the READY LED of the controller on  
the array controller board stops flashing and enters the on state), turn off the shut  
down switch. Then, execute the Unpair command for paired disks under NEC  
Storage DynamicDataReplication, and turn on the shut down switch to complete  
the write operation.  
*3 – Even if you forget to turn off the shut down switch, the disk array unit starts  
normally when being turned on next time, and accepts I/O operation by the host  
system. (Normal operation)  
– Turning off the shut down switch does not influence general operation of the disk  
array unit.  
– When turning off the disk array unit again, turn off the shut down switch and then  
turn it on. The system starts writing data remaining in cache memory onto the  
disk drive.

(3) Turning off AC power  
Turn off the powers of the additional disk enclosure and disk array unit in the  
following procedure.  
a) Turn off the host system or FC-AL switch, and then perform the procedure  
explained in "(2) Notes on AC power-off".  
b) After finishing the operation in a, turn off the array controller and then all the  
disk enclosures including additional disk enclosures. Alternatively, turn off  
the array controller and all the disk enclosures including additional disk  
enclosures connected with the array controller at the same time.  
The additional disk enclosure has the redundant power configuration to prevent  
the entire unit from shutting down due to a single failure. Therefore, when  
turning off the disk array unit, turn off the two power switches at the rear of the  
disk enclosure.  
Be careful that data may be lost if you turn off the disk enclosures before the  
array controller.

7.3 LD (Logical Disk) Setting Procedure  
To use the additional disk enclosure, first install the disk drive and then set the RAID level  
of the installed disk drive, and assign the logical disk (LD) configuration. When the disk  
drives are added, the RAID level and logical disk (LD) must be set appropriately.  
Set the RAID level by using the "NEC Storage Manager", or contact the service engineer  
with expert knowledge in your service representative for setting of the RAID level.  
If the disk array unit is connected with NF9520-SH01E, changing the LD  
(logical disk) configuration may cause the OS to fail to recognize the logical  
disks.  
Be sure to restart the host system after changing the LD configuration.  
7.4 Spare Disk Setting Procedure  
Spare disk can be set only in RAID level 1, 5, or 10.  
Set the spare disk by using the "NEC Storage Manager", or contact the service engineer  
with expert knowledge in your service representative for setting of the spare disk.  
For spare disk, make sure to assign the disk drive in slot 14.  
If slot 14 already contains a disk drive for a spare disk, install the additional  
disk drive in slot 13.  
When you change a failing disk to a spare disk, confirm the following to get  
the spare disk to function normally:  
The capacity of the spare disk is equal to or greater than that of the failing  
disk.  
The rotational speed of the spare disk is equal to or faster than that of the  
failing disk.  
Therefore, if a large-capacity disk is defined as a spare disk, it can cover all  
the disks of a high-speed drive. However, if your disk array unit contains disks  
of different capacities or different rotational speeds, you should define a spare  
disk matching the capacity and rotational speed of each disk in order to clarify  
disk management.  
Up to 2 spare disks can be installed for each disk enclosure. Up to 16 spare  
disks can be installed for the entire disk array unit.

8. ACTION TAKEN AT OCCURRENCE OF FAULT OR  
ERROR  
The user may remove a defected component and a new component for the  
replacement depending on the description in this chapter. However, if so,  
NEC does not assume the responsibility for any damage of the additional disk  
enclosure and components and any influence resulting from the operation of  
the additional disk enclosure. NEC recommends that you ask your  
maintenance engineer of the maintenance service agent with expert  
knowledge on details of the additional disk enclosure to remove any defected  
component and install a new component.  
For the installation of two or more disk drives or the change of disk drive  
installation positions, perform the job for the disk drives one by one. The  
change of disk drive installation positions with any logical disks assigned may  
cause some data to be lost.  
WARNING  
If a trouble including smoking and bad smell occurs or a fault such as halting  
of two or more cooling fans is found, turn off the power and disconnect the  
power plugs from the AC outlets. Then ask your sales agent or maintenance  
engineer to inspect and repair the additional disk enclosure immediately.  
Using the additional disk enclosure as it is may cause electric shock or fire to  
occur. The user must never repair the additional disk enclosure because it is  
dangerous.  
CAUTION  
Note that your fingers may not be caught or hit on some object when your  
hands are entered into the additional disk enclosure.  
If a fault occurs in the additional disk enclosure, the SERVICE LED on the  
additional disk enclosure, the FAULT LED on the defected component, or  
the POWER FAULT LED goes on. If a fault occurs, contact your  
maintenance engineer of the maintenance service agent with expert  
knowledge or prepare the proper maintenance component and replace the  
defected component immediately.  
Perform the replacement job as quick as possible. Do not operate the  
additional disk enclosure for a long time in the state that one or more  
existing disk drive, power supply, or adapter is removed. Failure to follow it  
may cause a fault to occur.  
If you find the occurrence of an abnormal state such as smoking or bad  
smell, turn off the power and pull out the power plugs from AC outlets. Ask  
your maintenance service agent for inspection and repair immediately.

If a disk drive is defected, the SERVICE LED on the array controller is lit orange. In  
addition, the SERVICE LED on the additional disk enclosure in which the defected disk  
drive is installed and the FAULT LED on the defected disk drive are lit orange.  
The defected disk drive may be replaced with the powers of the disk array unit and  
additional disk enclosure remaining ON.  
If the FAULT LED on a disk drive is lit, the fault of the other disk with the same LDN  
causes the data to be lost due to interruption of redundancy. If the FAULT LED on a disk  
drive is lit, replace the disk drive immediately. Perform the replacement job as quick as  
possible. Do not operate the additional disk enclosure for a long time in the state that the  
disk drive is pulled out.
