5260 Front Panel

The 5260 is equipped with four LEDs on the front panel: the System LED

(sys), ATM LED (atm), DSL LED (dsl), and Ethernet LED (enet).

1 First, the sys LED will come on. It turns solid green when the unit

has finished passing diagnostic tests.

2 The enet LED will then begin to flash green when Ethernet traffic is

detected.

3 The 5260 will begin negotiation of the optimum transmission rate and

attempt to train the line at the highest rate available. This process

usually only takes a minute, but if renegotiation of data rates is

necessary, it may take several minutes during which time the 5260 is

not yet operational.

4 While the unit negotiates the DSL line rate, the DSL LED will blink

yellow/green alternately. The LED will turn solid green when a link is

established.

5 The dsl LED will show solid green when it is ready to transmit data.

The atm LED will flash green indicating traffic flow on the WAN

interface.
