LEDs on the back of
X4000
One red and one green LED on the back of the X4000 basic unit (see Figure 3-
2, page 39 ) indicate the general status of each of the individual interfaces.
If the green LED flashes or lights, this always means fault-free operation. If the
red LED flashes or lights, this indicates a fault.
You can obtain more detailed status information via the display, the Setup Tool
or an SNMP Management Tool.
