Despite the ratification of IEEE 802.3af-2003 and the support of the standard by
vendors, some customers may utilize a legacy power scheme supported by Cisco
switches. The following power adapter is specifically for Avaya IP Telephones
and can be used to power theses telephones from specific Catalyst power blades
(Catalyst is a registered trademark of Cisco Systems, Inc.).
The Avaya IP Phone Power Adapter (material code 700259369) was tested and
will work with the following:

• Catalyst 6000 Inline Power 10/100 BaseT Switching Module - (WS-X6348-
  RJ45V).
• Catalyst 4000 Inline Power 10/100 BaseT switching module - (WS-X4148-
  RJ45V).

More detail on implementation of IP Power options is covered in the IP Office IP
Phone Installation manual.
