Table 39 describes the capabilities of the Switch 7750 PoE power module.
The Switch 7750 provides power through Ethernet ports on the PoE-supported I/O
modules, supporting the maximum distance of 100 m (328 ft.).
When the Switch 7750 provides power remotely, each Ethernet port can provide
up to 15.4 W of power to the connected PD.
Fan Assembly
The fan assembly consists of two to four individual fans and is located on the right
side of the chassis:
■
4-slot chassis — 3C16871
■
7-slot chassis — 3C16856
The fans are directly connected to the backplane through connectors. Fan
operation fault signals are collected and transmitted to the system alarm board
through the backplane.
Figure 27 illustrates the fan assembly for the 7-slot chassis.
