Connecting The Disk Array Unit - NEC Storage S1300 User Manual

Connecting the Disk Array Unit

The manufacturer assumes no liability for damage to the disk array
unit resulted from improper connection by the user. The
manufacturer recommends you to contact your local service
representative for more information.
This chapter describes the basic procedure for connecting the disk array unit to the host
system and host bus adapter. Also read the User's Guide of the host system or host bus
adapter to which the disk array unit is connected for details.
When connecting a peripheral device to the disk array unit, make
sure to disconnect the power cord of the device from the AC outlet.
Failure to disconnect power may result in personal injury.

CAUTION
Any FC cable used for the connection of the disk array unit should be
approved by the manufacturer. Also, the length of the cable should be
within the rating range. If an FC cable not approved by the manufacturer 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
and get damaged. Do not drag any connector on the floor to prevent dust
from adhering to the connector.
Handle optical fibers carefully and gently.
The minimum bending radius of optical fiber should be 30 mm.
Dust and/or dirt may attenuate the optical power of optical fiber, causing
data errors. When inserting a fibre cable into the mating connector, clean
it using the following procedure.
1. Blow parts cleaning gas to the connector of the optical fiber cable for
several seconds.
2. Wipe the connector with non-woven cloth soaked with alcohol for
several times.
3. Blow the parts cleaning gas to the connector again.
