Connecting Cables

This chapter explains how to connect various cables to the ETERNUS DX.

Host Interface Cable Connection

Connect the ETERNUS DX to the connection destination using host interface cables. The connection procedure
varies depending on the type of host interface that is used for the ETERNUS DX.
If the host interface in the ETERNUS DX100 S5/DX200 S5 is iSCSI 10Gbit/s (10GBASE-SR), and an FC cable is used
for the connection, the SFP+ module must be installed in the host interface port before the cable is connected.
Prepare the same number of host interface cables as the number of host interface ports.
IMPORTANT
• To help with host interface cable management and prevent incorrect connections, attach labels to the
cables that show which end is for the connection origin and which end is for the connection destination.
• SAS 12Gbit/s host interface cables have the same connector type as the mini SAS HD cables between
enclosures. To prevent accidental connections to a DI port on the drive enclosure or the controller
enclosure with the host interface cable, check the connection destination port.
In addition, the cable connector of the host interface is plugged in an orientation that is different from
the connector of the mini SAS HD cables between enclosures. When connecting the host interface cable,
make sure that the tab is facing up.
• When connecting a host interface cable, check the direction of the connector tab and insert it all the
way in firmly.
When disconnecting a host interface cable, pull out the connector while holding its tab.
• If the host interface ports and host interface cable connectors have covers, remove the covers. Keep the
removed covers in a safe place where they will not be lost.
• When connecting the cables, position them so that they will not obstruct replacement of the power
supply unit or controllers by the maintenance engineer.
Note
This section uses a controller enclosure with two controllers as an example to explain the connection
procedure. When one controller is installed, this procedure is only applied to Controller 0 (CM#0).
• Wear a wrist strap or touch a metal part to discharge the human body's natural
static electricity before starting each operation. Failure to discharge static
electricity may cause failure in the ETERNUS DX.
