The switch module is powered from the blade enclosure backplane. The switch module does not have a fan. The blade enclosure provides temperature management.

The switch module connects internally to the management module through 100BASE-T Ethernet links. You can manage the switch modules through the HP Onboard Administrator management module on a management network that is isolated from other switch traffic. You can manage the switch module through the RS-232 console port that uses an RJ-45 connector in the switch module front-panel. You can also manage the switch module through any of the external uplink ports.
