Table 2–1 (Cont.) Isolating Network Connection Faults
Symptom Probable Cause Action
Faulty module. Connect a loopback connector:
use one side of a BN24E cable
for the ST connector and use
PN 12-35619-03, with the
module cable, for the UTP
connector. Observe the result:
If the port LED for the
connector changes to solid
green, a problem exists
with the cable or the
concentrator.
If the port LED continues
flashing green, replace the
PMC Adapter module.
If no loopback connector is
available, test the cable between
the concentrator and the
module.
If you verify that the cable is
good, test the concentrator. If
the concentrator is functional,
replace the module.
Verifying the PMC Adapter on the Network
To verify that the module is operational in the network, use the ping,
telnet/rlogin, and ftp services of your TCP/IP environments.
• To establish a valid 100-Mb/s connection, connect a UTP Category
5 cable either point-to-point, or to a 100BASE-TX hub.
• To establish a valid 10-Mb/s connection, connect a UTP Category
3, 4, or 5 cable either point-to-point, or to a 10BASE-T hub.
Refer to Figure B–1 in Appendix B for the connector pin assignments.
Installation of the module is now complete.
