Industrial Ethernet OSM/ESM Network Management

Table 7-1 Troubleshooting
No. RemedyPossible CauseProblem
The firmware was not
downloaded completely
(power failure when saving
the new firmware) or the
OSM/ESM self test
detected a fault.
You can recognize this state after the
OSM/ESM has started up because the
fault LED is lit permanently and the
display LEDs on the front panel of the
OSM/ESM do not switch over when you
press the button.
Download the firmware again if this
problem occurred during downloading of
the firmware, see Section 6 and restart
the OSM/ESM.
If you have not downloaded firmware,
restart the OSM/ESM. If the problem
persists, the OSM/ESM self test has
detected a problem that it cannot
eliminate.
Send in the module to your SIEMENS
service center for repair.
Faults detected by the self test are logged
if you connect a PC with the
Hyperterminal program to the serial port of
the OSM/ESM, see Appendix B, and run a
cold restart on the OSM/ESM (power
off/power on).
3 Port Status LED OFF,
although a DTE is
connected to the port.
Problem on the port, the
DTE or the transmission
line.
Connect the station briefly to a different
OSM/ESM port and check whether the
problem persists.
If yes, check the transmission line to the
DTE and check whether the DTE is turned
on. If you are using optical cables, clean
the connectors.
4 10/100 Mbps port
performance low.
The partner port is not
autonegotiating and is
operating in the full duplex
mode.
Using Web-Based Management or the
CLI set the OSM/ESM port to the full
duplex mode (autonegotiation disabled).
5 No connection via the
serial port of the
OSM/ESM to the
connected PC.
Cable function,
incorrectly set
Hyperterminal program on
the PC,
incompatible transmission
rate.
Check the cable.
Check the settings in the Hyperterminal
program.
Check the transmission rate (default 115
Kbauds).
6 No access to CLI
commands.
Access only with
administrator password.
Enter admin as the login and then enter
the administrator password (the default is
admin).
7 No IP connections. The IP address was not
assigned.
Set the IP address and subnet mask
using the CLI.
