4. Repeat Step 1 on page 13 through Step 3 on page 13 for the partner node.
5. Cable the dual-port expansion adapter Port b, of the local node, to the partner
6. Cable the local storage expansion unit 1 Channel B ESH2/ESH4 or AT-FCX
7. Repeat Step 6, connecting Channel B output to input, for any remaining storage
8. Repeat Step 5 through Step 7 for the partner node.

Connecting a gateway to external storage

You must use fiber-optic cables to connect a gateway to external storage on a Fibre
Channel SAN.
See the Gateway Interoperability Matrix at the following web page for supported
third-party storage for your N7000 series system.
www.ibm.com/systems/storage/network/interophome.html
Refer to the documentation for your external storage for additional information.

Connecting your N7000 series system to a third-party device

You can connect third-party devices to your N7000 series system through an
optical Fibre Channel interface using any Fibre Channel port on the back of the
chassis.
The N7000 series systems only support third-party devices with an optical Fibre
Channel interface. For supported devices for your system, see the Interoperability
Matrix on the IBM N series support website, which is accessed and navigated as
described in "Websites" on page xx.
Refer to the documentation that comes with the third-party device for connection
information.

Rules for connecting the third-party devices

Observe the following rules for connecting the third-party devices:
v Use a fiber-optic cable that is:
v An unsupported tape backup device might cause the system to halt. To verify

Note: The AT-FCX and ESH2/ESH4 modules are self-terminating. The
ESH2/ESH4 does not have a terminate switch.
