The G48P I/O 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 I/O module supports the IEEE 802.3af 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. ExtremeXOS 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 I/O 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 I/O module has the following LEDs:
● Module status
● Module diagnostics
● Port status
● Power status
For information about the LEDs and their activity on the G48P I/O module, see “I/O Module LEDs” on
