You can add an optional S-POE daughter card to the 8900-G48T-xl I/O module to provide Power over
Ethernet (PoE) functions in this module. With an installed S-POE card, the ports can deliver PoE to an
attached device, in addition to the usual Ethernet connection, using a single cable. The 8900-G48T-xl
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 software 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
In the default configuration of the 8900-G48T-xl I/O module, 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 8900-G48T-xl I/O module has the following LEDs:
•
PoE present
•
Module status
•
Module diagnostics
•
Port status
For information about the LEDs and their activity on the 8900-G48T-xl I/O module, see

8900-G48X-xl I/O Module
The 8900-G48X-xl I/O module (
see the following figure
) has 48 unpopulated SFP-based 1-gigabit
Ethernet ports.
