Notes:
* The 10-port 4 Gb SAN Switch Module can be installed in the BladeCenter S; however, by doing so, you
lose the ability to connect to the BladeCenter S Disk Storage Modules (DSMs). The Fibre Channel I/O
module goes in place of the SAS I/O module that is needed to connect to the DSMs.
** When the I/O module is installed in a BladeCenter T unit, the internal ports operate up to 2 Gbps, and
the external ports operate at speeds up to 4 Gbps.
† When the I/O module is installed in standard I/O bays of a BladeCenter HT unit, the internal ports
operate up to 2 Gbps, and the external ports operate at speeds up to 4 Gbps.
‡ When the I/O module is installed in an MSIM-HT, the internal ports operate at 4 Gbps, and the external
ports operate at 4 Gbps.
The BladeCenter chassis have the following bays:
BladeCenter S, E, and T have four standard I/O bays (1, 2, 3, and 4)

BladeCenter H has four standard I/O bays (1, 2, 3, and 4), two bridge bays (5 and 6), and four

high-speed bays (7, 8, 9, and 10)
BladeCenter HT has four standard I/O bays (1, 2, 3, and 4) and four high-speed bays (7, 8, 9, and 10)

The QLogic 4 Gb SAN Switch Modules fit in a standard I/O bay (bays 1-6) and, with the addition of the
Multi-Switch Interconnect Module (MSIM) in the BladeCenter H, can also fit in a high-speed I/O bay (bays
7-10). The QLogic 4 Gb SAN Switch Modules are not supported with MSIM-HT in high-speed bays of the
BladeCenter HT chassis.
