36 IBM BladeCenter JS23 and JS43 Implementation Guide
The BladeCenter HT chassis allows for either 12 single-slot blade servers or six
double-slot blade servers. However, you can mix different blade server models in
one chassis. The BladeCenter HT chassis ships standard with one Advanced
Management Module. This module provides the ability to manage the chassis, as
well as providing the local KVM function. The optional redundant Advanced
Management Module provides the IBM BladeCenter HT with higher levels of
resiliency. This module provides clients with easy remote management and
connectivity to the chassis.
The BladeCenter HT does not ship standard with any I/O modules. You need to
choose these I/O modules depending on your connectivity needs. An Ethernet
Switch Module (ESM) is required in I/O module bays 1 and 2 to enable the use of
both Ethernet ports on a blade server. The I/O modules required in I/O module
bays 3 and 4 depend on the I/O Expansion Card installed in the blade servers.
High-speed switch modules can be installed into I/O bays 7 through 10, and are
used together with high-speed expansion cards installed into blade servers. I/O
bays 1 through 4 can also be used for bridge modules.
