Troubleshooting Procedures
Virtual terminal sessions
disabled in host
Check host settings to verify that the virtual terminal ses-
sions are enabled. For example, check NOCONN setting
on the SEL-2030.
Incorrect subnet mask set-
ting (SUBNETM)
Verify that devices you are connecting to are set with the
proper subnet mask. Verify that the IP address of both
devices places them in the same subnet.
Cannot Log In as FTP Client
Not properly connected to
Ethernet network
Verify connections to the Ethernet network. Verify that the
Ethernet network is connected to either the A or B network
port indicated by the SEL-2701 LEDs and that the medium/
data transmission speeds are correct. Check Pwr/Tx and
Lnk/Rx LEDs.
Using incorrect IP address Verify that you are using the correct IP address (IPADDR).
FTP connections disabled Verify the SEL-2701 FTPSERV setting.
Incorrect subnet mask set-
ting (SUBNETM)
Verify that devices you are connecting are set with the
proper subnet mask. Verify that the IP address of both
devices places them in the same subnet.
Cannot Browse With MMS Browser
Not properly connected to
Ethernet network
Verify connections to the Ethernet network. Verify that the
Ethernet network is connected to either the A or B network
port indicated by the SEL-2701 LEDs and that the medium/
data transmission speeds are correct. Check Pwr/Tx and
Lnk/Rx LEDs.
Using incorrect OSI net-
work NSAP address
Verify that you are using the correct NSAP address
(NSAP).
UCA2 disabled Verify the SEL-2701 ENUCA setting.
Does Not React to Incoming GOOSE Messages
Not properly connected to
Ethernet network
Verify connections to the Ethernet network. Verify that the
Ethernet network is connected to either the A or B network
port indicated by the SEL-2701 LEDs and that the medium/
data transmission speeds are correct. Check Pwr/Tx and
Lnk/Rx LEDs.
GOOSE message sender
not detected by SEL-2701
Verify GOOSE monitor text ID setting (GOSIEDn). Con-
nect to the SEL-2701 user interface and use the SEL-2701
GOOSE command to determine if a GOOSE sender was
detected. Use the GOOSE R command if it is necessary to
detect active GOOSE senders.
