is a fault that exceeds alarm thresholds or another type of 3021 failure.
This switch is used for local testing and setting the SUPV port rate when downloading firmware for the Flash PROM. For testing, setting the switch to LOC performs a network LLB and setting the switch to FAR sends fiv e seconds of in-band loop code and then sends the BERT pattern selected in the user interface. The default pattern is QRSS.
These two small, recessed LEDs indicate supervisory/network manager port activity.

Switch S2 sets the unit address. When using the
3021 with an 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 factory default set­ting of 1 positions are Down.
Switch S2 has eight positions used to create an 8-bit binary code for an address i n the range of 1 to 50. Switch position S2 -1 is the lea st sign if­icant bit (LSB) and S2 -8 is the most significant bit (MSB). If a switc h is down, its value is 0. If up, its value is that of the upper location. The values ar e additive. For exa mple, to set a unit address to 5, position S2 -3 (binary value is 4) and position S2 - 1 (bi nary value is 1) would be set Up for a unit address of 5 (4 + 1). All other positions would be set
