Installing the Modules

Default Port Configuration

If the slot in which you installed the module was empty the last time the switch

was either rebooted or reset (or the power to the switch was cycled), then the

module will use preconfigured default parameter values that will work for

most networks.

The default port configurations for connection parameters are:

■ Ports Enabled: Yes

■ Mode:

• 10/100/1000-T zl Modules: Aut

o — The port auto negotiates speed

(10, 100 or 1000 Mbps), communication mode (half or full duplex),

and MDI or MDI-X port operation.

Note If you configure the port to one of the fixed 100 Mbps modes, the port will

then operate only as an MDI-X port.

• Du

al Personality ports - (mini-GBIC ports using Gigabit-SX,

gabit-LX, and Gigabit-LH ports): Auto — The port always

operates at 1000 Mbps and full duplex. The setting is Auto for best

link establishment with other devices.

• Gi

gabit-SX, Gigabit-LX, and Gigabit-LH ports in mini-GBIC zl

dule: Auto — The port always operates at 1000 Mbps and full

duplex. The setting is Auto for best link establishment with other

devices.

■ Flow Control: Disabled

■ Advanced features — Spanning Tree, Trunking, Meshing, VLANs, IGMP,

LACP, Routing, Class of Service, Security, and so forth: all Disabled

If necessary, configure the port(s) in the module by using the switch console

the web browser interface. For more information, see the Management and

Configuration Guide that is on the HP Web site at www.hp.com/networking/

support, and the online Help provided in the console and web browser inter-

faces. If the default port configuration listed above is acceptable for your

work, then skip this process.

Note By default, all ports on the J8702A and J8705A modules have PoE power

enabled. Ports on the J9307A and J9308A modules provide PoE+ power. For

information regarding customizing PoE and PoE+ ports refer to the HP Power

over Ethernet (PoE/PoE+) Planning and Implementation Guide that is on

the HP Web site at www.hp.com/networking/support.
