Troubleshooting for the Base Station
Problem: The LED indicator on the base is fast flashing red (500 mS on/500 mS off) and does not
show steady green after the Ethernet cable is plugged in.
Solution: The LED indicator on the base fast flashes red during firmware upgrades, which may occur
when the base is first powered on. The upgrade can take up to 10 minutes to complete.
Problem: The LED indicator on the base is flashing green (1 second on/1 second off) and does not
show steady green after the Ethernet cable is plugged in.
Solution: The base is unable to obtain an IP address from a DHCP server. Check that a DHCP server
is available by plugging a laptop or other device into the Ethernet cable.
Problem: The LED indicator on the base is winking green (800 mS on/200 mS off) and never becomes
steady green.
WARNING!
Never unplug a base while the LED indicator is fast flashing red or the base may be
permanently damaged.
