4-32 SANnet II 200 FC, SATA, and SATA SE Array Installation, Operation, and Service Manual • March 2005
Note –
The connection of a FC, SATA, or SATA SE array to Fibre Channel HBAs that
use different speeds (1 Gbit and 2 Gbit) on the same channel is not supported. You can,
however, mix 1-Gbit and 2-Gbit Fibre Channel HBAs on different channels. This
limitation is due to the design of SANnet II 200 Fibre Channel array port bypass
circuitry and the inability of Fibre Channel to support auto-negotiation in a multi-drop
loop configuration.

Use fiber-optic cables to connect host channels to Fibre Channel HBAs on your host
computers or to other devices such as storage switches.
computers or to other devices such as storage switches.
1. Connect a fiber-optic cable to an HBA or FC port on each host or storage switch you
want to connect to the array.
2. Connect the SFP connector at the other end of each of these fiber-optic cables to host
channel SFP connectors on the back of the array.
If there is no SFP connector in the port you want to use, first insert an SFP connector
into the port as described in “Changing Your SFP Configuration” on page 4-24.

Power-On Sequence
Power on the equipment in the following order so the host computer discovers all
connected arrays:
connected arrays:
1. Expansion units
2. RAID array
3. Host computers
If an array is connected to a host using a serial port connection and powered on, the
host terminal window displays a series of messages, as shown in the following
example.
