Figure 67 shows the G48P module.
The G48P module has 48 autosensing 10/100/1000BASE-T ports that use standard RJ-45 connectors and
that can deliver Power over Ethernet (PoE) to an attached device as well as the usual Ethernet
connection, provided by one cable. The G48P module supports the IEEE 892.3af PoE specification.
When powered devices (PDs) are connected to a port, the PDs are discovered and classified as 802.3af-
compliant or as legacy devices. ExtremeWare XOS implements the following functions:
Enables the port for discovery, classification, and power delivery
Enforces port power limits by denying power to a device exceeding the configured limit
Enforces class limits by denying power to a device exceeding the class limit
Reports and tracks port power faults
The default configuration of the G48P module is as follows. All ports:
Are added to the default VLAN as untagged
Inherit the properties of the default VLAN (for example, protocol type and VLANid)
Operate in autonegotiation mode
The G48P module has the following LEDs:
Module status
Module diagnostics
