When JS23/43 blades with CFFh cards are installed in a BladeCenter H or HT
the cards connect to the high speed bays 7, 8, 9, and 10 depending on the ports
on the card. These module bays have a horizontal orientation. (The standard
module bays have a vertical orientation.)
When JS23/43 blades with a supported CFFh card are installed in a BladeCenter
S the cards are connected to Bay 2
Some CFFh cards utilizes the high speed bays, but uses standard modules for
connectivity. This connectivity is achieved by using the Multi-Switch Interconnect
Module (MSIM). One MSIM

gets installed in Bays 7/8 and one in Bays 9/10.
Each MSIM can be populated with a standard Fibre Channel switch module and
an Ethernet switch module for the BladeCenter.
Figure 4-5 on page 79 shows a diagram of the MSIM and the type of switches
that can be installed in the module bays. Refer to BladeCenter Interoperability
Guide for details about which switches are supported in the MSIM. The guide can

A interposer card is required for each MSIM to install in a BladeCenter HT chassis. Contact your
IBM sales representative for information about ordering interposer cards.
