A Gigabit Ethernet interface’s LEDs are not on.
1
Make sure the interface is enabled.
2
Make sure that the interface’s speed and duplex settings match those on the port on the peer
Ethernet device.
3
Check the copper or fiber optic Ethernet cable and connections between the interface and the
Ethernet switch or router.
4
If the interface is an SFP slot, check the transceiver.
5
Make sure that the peer Ethernet device is functioning properly.
6
If the Ethernet cable and peer Ethernet device are both OK and the LEDs stay off, there may be a
problem with the interface. Contact your vendor.
A SFP slot’s LNK LED turns on and off intermittently.
1

28.2 IES Access and Login
I forgot the IP address for the IES.
1
If you forgot the IP address of the in-band management ports (the Gigabit Ethernet ports, for
remote access), try to log into the out-of-band management port (the MGMT port, for local
access). If you were using the out-of-band management port, try the in-band management port.
The default in-band IP address is 192.168.1.1. The default out-of-band IP address is
192.168.0.1.
2
Use the CONSOLE1 port to log into the IES.
