ICM modules supported by the blade enclosure are classified into switch modules and
straight-through modules (also known as cascading modules in some manuals). The BX720E is
a type of switch module. Both ICM and switch modules mentioned in this document refer to the
BX720E.
Product overview
As an Ethernet switching control module inside the blade enclosure, the H3C UniServer BX720E
switch module (BX720E for short) provides data switching functions for servers installed in the front
slots of the blade enclosure and centrally provides external data ports, to achieve the communication
between blade servers and external networks.
Figure 1 shows the appearance of the BX720E.

Redundancy of devices
Up to six switch modules can be installed in a blade server chassis. For more information about the
installation position, see
Figure 2 . Switch modules in slots 1 and 4, 2 and 5, and 3 and 6 are
interconnected by the internal ports of the switch modules in pairs to form three pairs. Each pair can
be used as a switching plane, and you can configure the pairs of switch modules in active/backup
mode as required.
