Cuttable Trace Options And Locations; Cuttable Trace Definitions - Intel NetStructure ZT 5504 Manual

Cuttable Trace Options and Locations

The ZT 5504 contains several cuttable traces (zero Ω shorting resistors) that allow the user to
configure certain options not configurable through the BIOS Setup Utility. The
Locations" figure shows the placement of the ZT 5504's cuttable traces. The
Locations" table provides a quick cross-reference for the cuttable trace descriptions that follow.
There are two types of cuttable traces on the ZT 5504: single-option and double-option. Single
option cuttable traces are implemented using 0603 surface mount pads. A zero Ω shorting
resistor is then soldered between these pads to make the connection. Double option cuttable
traces (CTx, CTy, CTz) are implemented using three 0603 size surface mount pads. The
zero Ω shorting resistor is then soldered between one set of pads, depending on the chosen
option.
CAUTION:
These should not be modified by the user. Modifications to documented cuttable traces
should only be performed by a qualified technician familiar with surface mount soldering
techniques. The product warranty is voided if the board is damaged by customer
modifications.
