Preventive Action

Consider job site expansion and maintenance strategy and the options
suggested below to decide what update or upgrade plans might best fit
this customer's overall operation.
Consider the following risks and options for your customers:
•
Advise the customer of a potential problem when line power is
cycled to the NU-PWR101 power supply. We are dedicated to
maintaining a good customer relationship and are proactive in
notifying customers of the potential for a problem. Early
notification allows the customer to budget for preventive
measures and to implement them in an organized manner.
•
Caution the customer to avoid cycling line power to a large
number of units simultaneously as is done during standby power
testing.
Solution
Suggest updating the existing NU-PWR101 power supplies to
NU-PWR101-7MNT power supplies. The Repair and Return
procedure is an effective and inexpensive method to address this
situation.
The Repair Center schedules a swap and upgrade timetable for the
units on your job based on availability of ship-ahead power supplies to
get your swapout started.
The success of this program depends on installing these updated units
according to the schedule and returning the replaced units
immediately.
The Repair and Return procedure is as follows:
1. Place a separate order for each job requiring replacement
NU-PWR101-7MNT. Only replacements ordered by the
NU-PWR101-7MNT code number are available at this lower price
option. You are billed at full price and a credit is issued upon
return of the replaced units.
2. Specify the total quantity of power supplies required for the job.
3. Specify the want date or dock date for shipment. This makes it
easy to schedule multiple shipments as determined during the
initial call to the Repair Center. No other items can be on the same
order. Identify all the jobs requiring attention, and schedule
replacement at a reasonable rate and timetable to allow the Repair
Center to plan the resources needed to meet the requirements.
