ADC EMU-830 Manuale Utente

2-9

One or more shelves can be remotely managed by connecting an external modem to the RS-232/RS-485 SLIP port. 
However, when managed through the SLIP port, each shelf must be assigned a unique IP address (only one shelf is 
accessed with each dial-up connection). 

show WorldDSL shelves managed by SNMP 

through SLIP.

To connect an external modem to the RS-232/RS-485 SLIP port:

4

Connect a serial cable (with pinouts as specified below) to the EMU console port connector (DB-9F) of 
the local shelf.

5

Plug the other end of the cable into the serial port on the back of the modem.

6

At the back of the modem, plug a dedicated telephone line into the RJ-11 port labeled LINE or TELCO.

7

Plug the modem into an external power source and turn it on.

8

Configure the EMU modem parameters for remote alarm reporting as instructed in 

.

 See 

 for RS-232/RS-485 SLIP port configuration.

This procedure requires the use of a 25-wire straight-through cable, with a male DB-25 connector on each 
end of the cable (see 

).

1

Connect one end of the 25-wire cable to the RS-232/RS-485 (SLIP) connector on the EMS shelf.

2

Connect the other end of the cable to a standard modem.

3

If the modem has configuration switches or jumpers, set the switches or jumpers for factory default 
operation. Refer to the modem user manual for more information.

4

At the back of the modem, plug a dedicated telephone line into the RJ-11 port labeled LINE or TELCO.

5

Plug the modem into an external power source and turn it on.

The modem-to-EMU serial cable must have the connector pinouts shown in 
Figure 2-7 to function correctly.
