Types of Service Available
If your power supply fails within three years of original purchase, Agilent 
Technologies will repair or replace it free of charge. If your unit fails after your 
three year warranty expires, Agilent will repair or replace it as a very 
competitive price. Agilent will make the decision locally whether to repair or 
replace your unit.
Standard Repair Service (worldwide)
Contact your nearest Agilent Service Center. They will arrange to have your 
power supply repaired or replaced.
Express Exchange (U.S.A. only)
You can receive a replacement Agilent E3633A or E3634A via overnight 
shipment for low downtime.
1 Call 1-800-258-5165 and ask for ‘‘Express Exchange.’’
• You will be asked for your shipping address and a credit card number to 
guarantee return of your failed power supply.
• If you do not return your failed power supply within 45 days, your credit 
card will be billed for a new Agilent E3633A or E3634A.
• If you choose not to supply a credit card number, you will be asked to send 
your failed unit to a designated Agilent Service Center. After the failed unit 
is received, Agilent will send your replacement unit.
2 Agilent will immediately send a replacement Agilent E3633A or 
E3634A to you via overnight shipment.
• The replacement unit will have a different serial number than your failed 
unit.
• If you can not accept a new serial number for the replacement unit, use the 
Standard Repair Service option described above.
• If your failed unit was ‘‘in-warranty,’’ your replacement unit continues the 
original three year warranty period. You will not be billed for the 
replacement unit as long as the failed unit is received by Agilent.
• If your three year warranty has expired, Agilent will bill you for the Agilent 
E3633A or E3634A exchange price - less than a new unit price. Agilent 
warrants exchange units against defects for 90 days.
