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.
Note In Auto mode, you can see the network speed being 
used by checking the LEDs at the RJ-45 connector. 
See p.1-8.
