The Verilink 1024 chassis is designed to hold from
one to twenty-fou r modules.
The front view figure shows the chassis with brackets for a 19-inch rack. The rear panel NMS and power connections are described on the reverse side.
Each module inte rf ac es the c ha ssis bac kpl ane b oar d
through two card connectors. With these connectors,
each module receives a −48 VDC power source and
exchanges control signals with the rear panel chassis
connectors. The chas sis cont ains no ac tive components.
Rack mounting bracket s are reversible for sta ndard
19- and 23-inch racks. To install the chassis in a
rack, insert two screws through both the left and the
right mounting b rackets. Please note: In order to
meet GR-1089 grounding requirements, the chassis
must be installed using t hread-forming screws with
external tooth lock washers.

Each unit in the NMS chain must have a unique address. All units in the chain must use the same
NMS bit rate.

Power Connections
The chassis is designed with two power buses connected to TB1 (te rminal block 1). The A bus feeds
the slots 1 through 12 . The B bus feeds slots 13
through 24. Connect a Frame Gr ound lea d (18- to
20 - gaug e wire) to pin 2 before applying power to
the unit. Connect the other end of this lead to an appropriate frame ground .
NOTE: The maximum current draw of a
fully loaded chassis i s 4 amperes. The
Verilink 1042 power shelf can su pply a ma ximum of 4 amperes (refer to the c onfiguration guide for specifications). Ensure that
the proper fuse size is used.
