Switch Module All non- management modules (those without a serial management port), are referred to as switch modules. HP Cluster Platform solutions use the HP ProCurve 9300 1000Base-T Module (16-port) as the switch module (J4895A), as show in Figure 8-4. The module provides 16 RJ-45 connectors for Cat5 cabling. You can connect each port to a 100 Mbps or 1000 Mbps segment. The ports automatically detect the speed of the network and configure themselves accordingly. You also can manually configure a port for 100 Mbps or 1000 Mbps. The ports also support automatic MDI/MDIX crossover.

Switch Module
All non- management modules (those without a serial management port), are referred to as
switch modules. HP Cluster Platform solutions use the HP ProCurve 9300 1000Base-T Module
(16-port) as the switch module (J4895A), as show in
Figure 8-4
. The module provides 16 RJ-45
connectors for Cat5 cabling. You can connect each port to a 100 Mbps or 1000 Mbps segment.
The ports automatically detect the speed of the network and configure themselves accordingly.
You also can manually configure a port for 100 Mbps or 1000 Mbps. The ports also support
automatic MDI/MDIX crossover.

Management Module
Management modules provide a serial port for console access, and also provide additional port
density to the system. The reset button, which is recessed to prevent it from being pushed
accidentally, allows you to restart the system. Install the management module in any chassis
slot. Each system requires at least one management module.
