80 Switch Feature Overview
PoE Port Capabilities and Power Limits
Table 2-1 identifies the PoE capabilities of each switch.
NOTE: These power limits are measured at the PSE (switch). Due to insertion losses, the
power received by the PD may be less than the requested power feed. For example, a
class 8 device requesting 90W power over a Cat5e/6 cable will receive between 72W and
95W depending on the insertion loss.
