CR-SEH
Troubleshooting
Ethernet Link LED is not on.
Check the power LED on the CR-SEH. Check the Ethernet cable, making sure that it is fully connected.
Check the gender of the Ethernet cable. The CR-SEH can drive CAT5 cable to a maximum length of 100
meters. If a longer cable length is needed a signal regenerating device must be placed in line.
Cannot telnet to CR-SEH.
Check the power LED on the CR-SEH. Check the Ethernet cable, making sure that it is fully connected.
Make sure the CR-SEH has a valid, unique IP number on the network. If you are attempting to telnet to
the CR-SEH through a router, make sure that the correct address has been entered in the routing table. If
the telnet security is enabled, make sure a device with an IP address on the allowed list is being used to
initiate the telnet session.
The CR-SEH does not respond through the Console Port.
Check that a straight through serial cable is being used if connected to a PC. If you are not using
WinSEM, verify that the host serial port is set for 38.4Kbps, 8 data bits, 1 stop bit and no parity. If you
are using a terminal program, make sure that it is set up to transmit carriage returns when entered from the
keyboard. If the console security feature is enabled, the correct password must be entered at the prompt to
gain access to the CR-SEH command line.
Bridges do not link (RF Link LED is not on).
Check that one bridge is configured as a master. Also check that the bridges are set to the same network
number.
