Verilink PRISM 4051 (34-00253.2) Product Manual - Manual (Page 16)

10 C HAPTER 2: I NSTALLATION
Switch S4 has eight positions that are used to create an 8 -bit binary code for an
address in the range of 1 to 50. Switch position S4 -1 is the least significant bit
(LSB) and S4 -8 is the most significant bit (MSB). If a switch is down, its value is
0. If up, its value is that of the upper location. The values are additive. For
example, to set a unit address to 5, position S4-3 (binary value is 4) and position
S4 -1 (binary value is 1) would be set Up for a unit address of 5 (4 + 1). All other
positions would be set Down.
Network
Management
Connections Network management is accomplished via the NMS or S UPV port as described
earlier in this chapter. Each port provides a ComView NMS interface and can be
managed under SNMP/T
ELNET when connected to an 8100A Site Controller.
Supervisory (SUPV)
Connections
The front panel supervisory port, labeled SUPV, serves two functions. A modem
may be connected to the SUPV port for remote access or use of the COA (call on
alarm) feature. The terminal interface may be accessed through this port.
The SUPV port bit rate can be configured for 1200, 2400, 9600, and 19200 bps as
shown in SUPV Port Rate on page 2 -9. The default is 19200 bps. Refer to section
Ordering Numbers on page 4 for cable information.
The port is a serial RS-232 DCE port
configured for 8 bits, no parity, and 1 stop
bit. The physical connection is an 8-pin
modular jack with the following pinout
(see Table 2-15).
The unit firmware may be accessed
through this port (see Software
Configuration on page 23) as well as the
Call On Alarm feature (see Management
Parameters on page 34). This port is
accessed through either a direct connection or a dial-up connection via an
AT-command-set-compatible modem. The modem should be optioned to ignore
DTR, enable auto answer, inhibit command echo, and return verbose result codes.
If the unit is called and sent a break command before receiving the connect message,
the modem hangs up.
The COA feature works through the supervisory mode only.
NMS Port The PRISM 4051 is fully compatible with the Verilink 8100A Site Manager. The
8100A software system is used to manage small to large networks of Verilink
network access products.
NMS ports located on the rear panel of the 1051 chassis provide access to the
8100A Site Controller. The unit accesses the built-in 1051 chassis bus.
An element may be accessed by using an RS-232 connection from the serial port
of the computer running the 8100A program to the element’s SUPV port or the
