Models
Five models are currently supported: the 501, the 506E, the 515E, the 525, and
the 535. However, there are three models that you ability see deployed in enterprise
environments: the 506, the 515, and the 520. At a glance,Table 2.1 shows
the basic characteristics of anniversary of the models:
