If devices such as modems, printers, or fax boards are connected to an Ethernet
station node or a file server, they are not actually considered network
peripherals because they do not contain their own NICs. If the peripheral
you are troubleshooting does not contain its own internal NIC, troubleshoot
the device by linking to the appropriate procedure from the
main
symptom list
. For example, suppose that a modem or printer is connected
to an Ethernet station node or file server, and the Ethernet station node
or file server contains the NIC. In this case, you would vector to either
the
modem
or
printer
problem symptom. If the device does contain its own internal NIC, the procedures
on this page are applicable.
A network peripheral failure symptom usually is different from that of a
standard Ethernet station node. Both
a network peripheral and a standard
Ethernet station node contain a NIC, however, and access the segment through
the Ethernet rules. Because of this, they both can be assumed to have the
same logical network area of fault components, which is the respective network
peripheral's segment area, specifically, the network peripheral, the NIC,
the segment cable and the repeater or wiring hub port.
Some network peripherals access the Ethernet network with NIC and hardware/software
components, others just use NIC hardware with firmware contained within
PROM chips. Both configurations allow the assigned network peripheral to
access the segment through standard network access and they both operate
according to the Ethernet CSMA/CD operating-mode principles.
These procedures are generic as to the network peripheral manufacturer.
For some of the troubleshooting steps mentioned in this flow guide, you
should also refer to the network-peripheral manufacturer's documentation
for any special predefined methods for checking network-peripheral configuration
and for network-peripheral testing.
