Troubleshooting
This chapter provides information to aid in the diagnosis of common problems and issues
encountered when using the OmniConnect access devices. Included are complete list of ISDN
cause codes that the ISDN provider’s switch returns during ISDN call setup. These status and
error codes are logged by the OmniConnect/ISDN series access devices and are available
using serial console commands.
8.1.
Hardware
POWER LED IS NOT LIT
Check that the AC power adapter is plugged into a working 110V, 3-prong
outlet as well as the DC 12V connector on the OmniConnect access device. If
the problem persists, please contact technical support.
B1, B2 and D LEDs REMAIN LIT AFTER POWER-ON
This is an indication that on-board power-on diagnostics have failed. Please
contact technical support.
10BASE-T CONNECTIONS ARE NOT ACTIVE
Check that the correct cabling is being used to connect the OmniConnect access
device’s Ethernet ports to the network adapter. Immediately upon attaching the
cabling correctly, the corresponding Ethernet LED should light. If connecting
from another Ethernet repeater, ensure that only port 1 is being used and that the
MDI switch at the bottom of the box is switched to the ON position. See the
section on 10Base-T connections for more information.
WORKSTATIONS OR PCs ATTACHED TO THE OMNICONNECT
DEVICE USING ETHERNET CANNOT COMMUNICATE
Check to ensure that the green port LEDs on the OmniConnect access device are
lit. If they are not lit, check the cabling.
Check that the Ethernet driver software has been installed and TCP/IP or other
network protocol has been configured on the PCs.
If the OmniConnect access device’s DHCP server is enabled, run winipcfg to
ensure that the PC has been assigned an IP address correctly.
NO CHARACTERS OR DATA APPEARS ON THE TERMINAL OR PC
.
Check that the cable attached to the CONSOLE port on the OmniConnect access
device is connected to the correct COM port on the PC that is being used by the
terminal emulation software. Usually, this is COM1, COM2 or COM3.
Check that the port labeled CONSOLE is connected to the PC or terminal using
the appropriate DCE-to-DTE cable. A null cable should not be used. Also check
that the PC’s or terminal’s settings are VT-100 emulation, 9600 baud, no parity,
1 stop bit and 8 data bits.
GARBLED CHARACTERS OR DATA APPEAR ON THE TERMINAL
OR PC
This is primarily an indication of the incorrect baud rate setting. Ensure that the
appropriate COM port is set to 9600 baud.
