List of Field-Replaceable Units and Expansion Modules

This appendix lists

All field replaceable units (FRUs) in a LightStream 2020 multiservice ATM switch (LS2020 switch)
Expansion modules for NPs and line cards

(An expansion module includes everything needed to add a particular kind of card or module to an existing system.)

Part numbers for FRUs and expansion modules are provided in two tables:

Table A-1 lists current Cisco part numbers.
Table A-2 lists older numbers that have been superseded by the part numbers in Table A-1. Table A-2 is provided for the convenience of customers who have spares on hand that are labelled with the older part numbers. Orders for new parts must use the numbers in Table A-1.

At least one part number is listed for each item. For many items, two part numbers are provided: the internal manufacturing number, and the order number.

Part numbers for external data cables and power cords appear in the LightStream 2020 Site Planning and Cabling Guide. For descriptions of FRUs listed here, refer to the chapter entitled "Hardware Description."

Caution Before removing any components from the chassis, read the safety instructions in the chapter entitled "Hardware Troubleshooting." You can damage the system by removing components when you are not grounded.
