5.0 CONFIGURATION

All configuration is done through software auto-detection for the Model 2121/2135C. Once you have configured your mux or other equipment to be connected to the 2121/2135C, the unit is ready for operation. Observe that the serial port of the 2121/2135C is configured as a DTE and must connect to a DCE.

The LAN port also requires no configuration to connect to a 10BaseT Ethernet.

Note: The X.21 and V.35 Interface is configured as a DTE. The 2121/2135C will transmit and receive data to and from the DCE, based on the speed of the clocks received from the DCE.

On the LAN side interface, data is sent and received in burst mode at 10Mbps.

5.1 LED STATUS MONITORS

The 2121/2135C uses two LEDs on the Ethernet connection side. A green LED indicates that link connection to the network is established. The yellow LED displays status codes (See section 5.1.2 for status code information).

Seven, low power, LEDs located on the top of the 2121/2135C case indicate POWER and X.21 or V.35 signal activ- ity.

5.1.1 LAN side LEDs

The Model 2121/2135C features two LAN LEDs that monitor general operation status and the 10BaseT twisted pair link integrity. Figure 8 shows the LEDs located at the rear of the Model 2121/2135C. Following Figure 8 is a description of each LED function. Figure 8 shows the LEDs located on the top of the Model 2121/2135C.

5.1.2 LED Descriptions

The status LED blinks yellow from one to eleven times to indicate system status. Each pulse pattern is separated by a 2 second "off " period. Greater pulse patterns have higher priority (buffer saturation has greater priority than an empty MAC table).

Valid system statuses are:

1 pulse

=

system status ok

2 pulses

=

No MAC entries in the MAC address table

3 pulses

=

Clear to send (CTS) or Carrier Detect (DCD) from

 

 

base unit are not asserted

4pulses = IMRC2/IA buffer is saturated

5pulses = WAN receive frame(s) too large

6pulses = WAN receive frame(s) not Octet aligned

7pulses = WAN receive frame(s) aborted

8pulses = Detected WAN receive frame(s) with bad CRC

9pulses = Detected LAN receive frame(s) too large

10 pulses = Detected LAN receive frame(s) not Octet aligned 11 pulses = Detected LAN receive frame(s) with bad CRC

After a status code is displayed eight times and the associ- ated condition is removed, the status code will no longer appear.

The link LED glows green to indicate link integrity on the 10BaseT twisted pair line.

5.1.3 Power and DCE/DTE Interface LEDs

Seven LEDs indicate POWER and DTE/DCE activity on the front of the 2121/2135C.
