2.2.3 Connecting the S2A9550s in Dual Mode
For dual mode configuration only:
1.
Connect the “S2A LINK” ports on the two S2A9550 units using an Ethernet cable.
2.
Connect the “S2A COM” ports on the two units using an RJ45 cable.
2.2.4 Connecting the S2A9550
If you are using the SF family of enclosures with the S2A9550, please refer to Section C.2 for
information on how to set up the enclosures and connect them to the S2A9550. You may also
refer to to
Cabling & Switching Information for S2a 8500 & S2A9550 and Drive Enclosures

1.
There are ten disk channels on the S2A9550. The disk ports are labeled as follows
(Figure
2-1)
:
DISK A = Channel A DISK B = Channel B
DISK C = Channel C DISK D = Channel D
DISK E = Channel E DISK F = Channel F
DISK G = Channel G DISK H = Channel H
DISK P = Channel P (parity)
DISK S = Channel S (spare)
Using the ten copper SFP cables provided, connect these disk ports to your ten disk
channels. Make sure the latches on the transceivers are engaged.
2.
Each S2A9550 supports up to 4 Fibre Channel host connections. You may connect more
than four client systems to the S2A9550 with the use of hubs/switches and you can restrict
user access to the LUNs (as described in Section 2.3).
The Host ports (SFP) are numbered 1 through 4 as shown in Figure 2-1. Connect your host
system(s), hubs or switches to these ports. Make sure the latches on the transceivers are
engaged.
2.2.5 Selecting AL_PA for Your Drives
Each drive channel on the S2A9550 is a single Fibre Channel Arbitrated Loop. Hence, all the
drives on the same channel must have their unique Arbitrated Loop Physical Addresses—
AL_PA.
