ES-2810 ATM Uplink Module User Guide 1 - 3
Introduction
The three status LEDs on the left side of the ATM Module reflect the current state
of the module. Table 1 describes each LED.
1.2.1 ATM-Stack Connector
The 26-pin ATM-Stack connector adjacent to the Status LEDs is used to establish
the ATM uplink between the Ethernet network and the ATM ELAN. The port con-
nects to the Matrix Module in the stack.
1.2.2 ATM Uplink Port
The SC or RJ-45 ATM port provides the data bridge between the Ethernet stack and
a switch on an ATM ELAN. There is a transmit (TX) LED to the left of this port and
a receive (RX) LED to the right. Table 2 and Table 3 describe the states of the LEDs.
