5.5 Connecting Cables

Connect the HDD and system with the following cables. See Section 4.3 for further details of the

requirements for HDD connector positions and connecting cables.

• Power cable

• SCSI cable

• External operator panel cable (if required for NP model)

The general procedures and notes on connecting cables are described below. Especially, pay

attention to the inserting orientation of each cable connector.

CAUTION

Damage

1. Make sure that system power is off before connecting or disconnecting

cables.

2. Do not connect or disconnect cables when power is on. (except NC

model)

a) Connect power cable.

b) Connect the external operator panel (if required for NP model).

c) Connect the SCSI cable.

d) Fix the cables so that they do not touch the DE and PCAs, or so that the smooth flow of the

cooling air in the system cabinet is assured.

CAUTION

Damage

1. Be careful of the insertion orientations of the SCSI connectors. With the

system in which terminating resistor power is supplied via the SCSI

cable, if the power is turned on, the overcurrent protection fuse of the

terminating resistor power supplier may be blown or the cable may be

burnt if overcurrent protection is not provided.

When the recommended parts listed in Table 4.2 are used, inserting the

cables in the wrong orientation can be prevented.

2. To connect SCSI devices, be careful of the connection position of the

cable. Check that the SCSI device with the terminating resistor is the

last device connected to the cable.
