Positions S2-7 and S2-8 select the startup boot configura-

tion method as shown in Table 2-N.

Configuration Switch S3

Switch S3 (Figure 2-4) sets the configuration parameters

listed in the following paragraphs.

NMS R

Positions S3-1 and S3-2 set the bit rate for the network

management system as shown in Table 2-O.

SUPV P

ORT

Positions S3-3 and S3-4 set the supervisory port rate as

shown in Table 2-P.

DBU R

ATE

Positions S3-6 through S3-8 set the DBU port rate as shown

Address Switch S4

Switch S4 sets the unit address. When using the 4001 with a

8100A Site Controller, each element in a group must have a

unique unit address. As many as 50 units (with addresses from

1 to 50) can exist in a group. If the unit is not connected to a

site controller, the NMS unit address should be left at the fac-

tory default setting of 1 where Position 1 is Up and all other

positions are Down (see Figure 2-5).

Switch S4 has eight positions used to create an 8-bit binary

code for an address in the range of 1 to 50. Switch position S4-

1is the least significant bit (LSB) and S4-8 is the most signifi-

cant 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.

Interface Switches S5 and S6

Switches S5 and S6 are slide switches that set the unit to

either RS-232 or V.35. Both switches must be set to the

same selection (that is, RS-232 or V.35).
