ProCurve Switch vl Modules
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-TX vl Module: Auto — The port auto negotiates speed (10 or 
100 Mbps), communication mode (half or full duplex), and MDI or 
MDI-X port operation. If you configure the port to one of the fixed 10 
or 100 Mbps modes, the port will then operate only as an MDI-X port.
• All Gig-T vl Modules: Auto — The port auto negotiates speed (10, 
100 or 1000 Mbps), communication mode (half or full duplex), and 
MDI or MDI-X port operation. If you configure the port to one of the 
fixed 10 or 100 Mbps modes, the port will then operate only as an MDI-
X port.
• Gigabit-SX, Gigabit-LX, Gigabit-LH, 1000Base-T, and SFP 
ports in mini-GBIC and the Gig-T + 4-port SFP vl Modules: Auto 
— The port always operates at 1000 Mbps and full duplex. The setting 
is Auto for best link establishment with other devices.
• 100-FX MTRJ vl Modules: 100FDX — The port operates at 100 Mbps 
and full-duplex.
■ Flow Control: Disabled
■ Advanced features — Spanning Tree, Trunking, Meshing, VLANs, IGMP, 
LACP, Routing, Class of Service, Security, and so forth: all Disabled
If the default port configuration listed above is not correct for your network, 
configure the port(s) in the module by using the switch console or the web 
browser interface. For more information, see the Management and 
Configuration Guide for your switch, available on the ProCurve Web site 
www.procurve.com, and the online Help provided in the console and web 
browser interfaces.
