8 Brocade FCoE Switch Module for IBM BladeCenter: Installation and User Guide
FIGURE 3 HSSM bays for BladeCenter HT chassis
A compatible expansion card or converged network adapter (CNA) must be installed in each blade
server that you want to communicate with. To enable the switch module to communicate with a
blade server, at least one switch module must be installed in the BladeCenter unit. For details
about expansion-card installation, configuration, and use, see the documentation that comes with
the expansion card.
Installing a second switch module enables a redundant path and a separate connection from the
blade server to the external Ethernet network or Fibre Channel SAN.
The BladeCenter unit supports a maximum of two Brocade FCoE Switch Modules. The BladeCenter
H chassis supports a maximum of 14 compatible expansion cards and the BladeCenter HT chassis
supports a maximum of 12 compatible expansion cards.
Notes:
• The blade servers or BladeCenter units that are described or shown in this document might be
different from your blade server or BladeCenter unit. For additional information, see the
documentation that comes with your blade server or BladeCenter unit.
• If you are installing only one switch module, use high-speed module bay 7/8. This is preferred
over bay 9/10.
• When the switch module is installed in a BladeCenter unit, the internal ports operate at an
autonegotiated speed of 1 Gbps or 10 Gbps inclusive. The external FC ports can operate at 2,
4, or 8 Gbps (auto-negotiated) and the CEE ports operate at 10 Gbps.
