AT&T MERLIN LEGEND Release 3.1 Maintenance And Troubleshooting Manual page 26

Equipment
Detailed information about system programming is included in System
Programming and in System Programming and Maintenance (SPM) .
You can use either a DOS PC or a Master Controller (MCII or MCIII) to run
SPM. To connect a PC to the control unit, you need a 355AF adapter and a
D8W-87 cord.
NOTE:
On-site programming maintenance is preferred if it is feasible; remote
programming overrides on-site programming, except when on-site backup or
restore is in progress. See "On-Site Programming Maintenance" and "Remote
Programming Maintenance," later in this chapter, for details.
Tools
In addition to the maintenance terminal, you need the following tools:
EIA breakout box
Digital voltmeter (KS-20599 or equivalent)
110/66-type punchdown tool
Dracon TS21 or equivalent touch-tone telephone for testing
Assorted flathead and Phillips-head screwdrivers
Long-nosed and regular pliers
Wrist grounding strap
Replacement parts recommended by your technical support
organization
!
CAUTION:
Should you ever need to open a module and handle the circuit board,
use the wrist strap to connect your wrist to a suitable ground first.
Electrostatic discharge can destroy or severely damage the integrated
circuits in the power supply, processor, and modules.
