* When the I/O module is installed in a BladeCenter HT unit, the internal ports operate up to 2 Gbps, and
the external ports operate at speeds up to 8 Gbps.
The Brocade 8Gb SAN Switch Modules support the expansion cards listed in Table 4. Table 4 also lists
the chassis bays in which the switch module must be installed when used with each expansion card.
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 Brocade 8Gb 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 Brocade 8Gb SAN Switch Modules are not supported with MSIM-HT in high-speed bays of the
BladeCenter HT chassis.
