Troubleshooting
continued
If problems
persist
For problems not covered in the troubleshooting chart (see
“Troubleshooting: Table 6” on page 26), or if the problem
persists, follow this procedure:
1 Note the serial number and date of purchase of
the Interface Expander unit. Contact APC Cus-
tomer Support at the phone number or address on
the back cover of this manual.
2 Be prepared to provide a description of the prob-
lem. A technician will help solve the problem over
the phone, if possible, or will give you a return
material authorization (RMA) number.
3 If the Interface Expander unit is under warranty,
repairs are free of charge. If the warranty has
expired, there will be a nominal charge for repair.
4 Pack the Interface Expander carefully in its origi-
nal packaging, if possible. Do not use polystyrene
beads for packing. Damage sustained in transit is
not covered under the warranty. Enclose a letter in
the package with your name, address, RMA num-
ber, a copy of the sales receipt, daytime phone
number, and check (if applicable).
5 Mark the RMA number clearly on the outside of
the shipping carton. The factory will not accept
any materials without this marking.
6 Return the Interface Expander unit by insured, pre-
paid carrier to the U.S. address on the back cover
of this manual.
