Switches (HP JetDirect 300X and 500X)

The HP JetDirect 300Xand 500X Print Servers have configuration switches that should be used only if the print server fails to link on the network. The factory-default setting of all 3 switches down will suit most installations. These switches only apply to 10Base-T and 100Base-TX networks only.

When the first switch is set to Auto, the other two switch settings are ignored; the server auto-negotiates the link speed and duplex setting with the connected switch or hub device. Even with devices that don’t auto-negotiate, the print server detects the network link speed and uses half duplex.

Although nearly always unnecessary, you can control the settings directly by positioning the switches as shown in the table below, only if you are certain of the duplex setting and speed at which the switch or hub is operating.
