Figure 5:  Network with third-party APs 
 
The WSS 2300 supports many models of third-party APs with a few restrictions—see WSS 2300 
Release Notes
. All models of WSS 2300 have support for third-party APs, although 
implementation specifics may vary. In many cases, Nortel also supports VoWLAN over third-party 
APs. The APs must be L2 or directly attached to the WSS 2300. Note that this may require 
extending VLANs in the Centralized Campus model using WSS 2380s. The APs must be certified 
by SpectraLink as SVP compliant, and configured according to SpectraLink guidelines. You must 
also meet WTM 2245 engineering requirements. Details about supported third-party APs, valid 
network configurations, and other restrictions are beyond the scope of this document. 
2.2.2  Network design constraints 
While the previous sections discussed basic design types, the intent of the following topics is to 
drill down to the next level of detail and explore various design and interoperability issues starting 
with the physical layer (L1) moving up to L2 and L3 constraints. 
2.2.2.1 
Power over Ethernet (PoE) requirements 
The AP 2330 draws an average of 6 Watts (W) of power when idle, increasing to 7 W average 
under heavy load. The Ethernet Switch (ES) 460-24T-POE is capable of supplying up to a 
maximum of 370 W of power (assuming ES 460-24T-POE is in AC+DC mode with Network 
Energy Source [NES]) in some configurations. The ES 460-24T-POE with no secondary power 
source is capable of supplying an aggregate of 200 W, which is enough to power a full 
complement of 24 AP 2330s (assuming a draw of 7 W per AP). 
Also, you must carefully consider redundant power options for the ES 460-24T-POE if PoE is 
implemented. There are two external power supply options for the ES 460-24T-POE. The first is 
the Ethernet Switch Power Supply Unit (PSU) 10. In the event of a primary AC power source loss,
