5.5 Connecting Cables
Connect the IDD and system with the following cables. See Section 4.4 for further details of
the requirements for IDD connector positions and connecting cables.
• Power cable
• SCSI cable
• External operator panel cable (if required)
The general procedures and notes on connecting cables are described below. Especially, pay
attention to the inserting direction of each cable connector.
CAUTION
Damage
1. Check that system power is off before connecting or disconnecting
cables.
2. Do not connect or disconnect cables when power is on.
a) Connect power cable.
b) Connect the external operator panel (if required for system).
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 directions 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 direction 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.
