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 usually 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 by
checking the LEDs at the RJ-45 connector (see
page 3-5).
If the auto switch
is set to... And if the speed
switch is set to... And if the duplex
switch is set to... Then the settings
are...
