sure to provide a valid IP address to the DL3800. THere can be up to two
active telnet sessions at any given time. There is no way for a user to delete
the telnet session of another user.
Daisy Chaining
Multiple DL3800s can be daisy-chained together through the Terminal Port
to provide centralized network monitoring and management capabilities.
A ribbon-type cable with DB-9 connectors is available from Digital Link for
daisy-chaining DL3800s. The cable can be ordered to daisy-chain four
units (part # 154-00051-01), eight units (part # 154- 00052-01), or twelve
units (part # 154-00053-01). To place an order contact the Digital Link Sales
department at [phone].
If using a cable other than the above, see ÒTerminal ConnectionÓ on page
B-1 for Terminal Port pin assignments. With this cable, CTS (pin 8) must
be connected between DL3800s, but must not be connected to the terminal.
The one socket connector on the ribbon is to be connected to the terminal
or modem (if a remote site). The remaining plug DE-9 connectors are
connected to the Terminal. Each unit must be assigned a unique node
number.
When units are daisy-chained together, the local terminal must be
operating in Multidrop Mode. Each unit should be given a unique Node
Number.
NOTE: For detailed instructions on installing SNMP systems, refer to
the separate installation guides for these products.
