6.3 Procedure – Connecting Host Cables on an E2600 Controller-
Drive Tray
The type of HICs (SAS, FC, or iSCSI) must match the type of the host bus adapters (HBAs) or
network interface cards (for iSCSI only) to which you connect them.
See the examples in Section 6.4 Example cabling patterns, page 37 .
1. Perform one of these actions:
– You are using an FC HIC
Go to step 2.
– You are using either a SAS or an iSCSI HIC
Go to step 4. Connections for both SAS and iSCSI use copper cables with RJ-45 con-
nectors and do not require SFP transceivers.
2. Make sure that the appropriate type of SFP transceiver is inserted into the host channel.
3. If a black, plastic plug is in the SFP transceiver, remove it.
4. Perform one of these actions:
– You are using either a SAS or an iSCSI HIC
Starting with the first host channel of each controller, plug one end of the cable into
the host channel.
– You are using an FC HIC
Starting with the first host channel of each controller, plug one end of the cable into
the SFP transceiver in the host channel.
The cable is either an Ethernet cable with RJ-45 connectors for 1-Gb/s iSCSI or 6-Gb/s
SAS connections, or a fiber-optic cable for FC connections.
5. Plug the other end of the cable either into an HBA in the host (direct topology) or into a
Note:switch (fabric topology).
Note:
The SAS host interface does not support a switch topology.
WARNING!
Risk of exposure to laser radiation
Do not disassemble or remove any part of a Small Form-factor Pluggable (SFP) transceiver
because you might be exposed to laser radiation.
NOTICE!
Make sure that you have installed the HBAs. Refer to the documentation for the HBAs for
information about how to install the HBA and how to use the supplied configuration utilities.
NOTICE!
If Remote Volume Mirroring connections are required, do not connect a host to the highest
numbered host channel.
