Table 105
SFP LNK LED Troubleshooting
STEPS
CORRECTIVE ACTION
1
Make sure that the Ethernet port’s mode is set to match that of the peer Ethernet device.
2
Check the cable and connections between the SFP slot and the peer Ethernet device.
3
Check the mini GBIC transceiver.
4
Make sure that the peer Ethernet device is functioning properly.
If the cable, transceiver and peer Ethernet device are all OK and the LEDs stay off, there
may be a problem with the SFP slot. Contact the distributor.
Table 106
100/1000 LED Troubleshooting
STEPS
CORRECTIVE ACTION
1
Each 100/1000M RJ-45 Ethernet port is paired with a mini GBIC slot. The IES-1248 uses
one connection per pair.
2
Check the
Speed Mode
settings in the
ENET Port Setup
screen. Make sure that the
100/1000 Ethernet port’s connection speed is set to match that of the port on the peer
Ethernet device. When an Ethernet port is set to
Auto
, the IES-1248 tries to make a fiber
connection first and does not attempt to use the RJ-45 port if the fiber connection is
successful.
3
Check the Ethernet cable and connections between the 100/1000 Ethernet port and the
peer Ethernet device.
Use 1000Base-T 4-pair (8 wire) UTP Cat. 5 Ethernet cables with the RJ-45 interface.
4
Make sure that the peer Ethernet device is functioning properly.
If the Ethernet cable and peer Ethernet device are both OK and the LEDs still stay off,
there may be a problem with the port. Contact the distributor.
Table 107
Troubleshooting Data Transmission
STEPS
CORRECTIVE ACTION
1
Make sure that the Ethernet port has the appropriate mode setting.
2
Make sure that the IES-1248’s IP settings are properly configured.
3
Check the VLAN configuration.
4
Ping the IES-1248 from a computer behind the peer Ethernet device.
