G48Pe I/O Module
The G48Pe I/O module ( Figure 22 ) has 48 autosensing 10/100/1000BASE-T ports that use standard
RJ-45 connectors. In addition to the Ethernet connection, these ports can deliver Power over Ethernet
(PoE) to an attached device, using the same cable. The G48Pe I/O module supports the IEEE 802.3af
PoE specification. When an 8800 series switch is running in dual-MSM mode, this module will be
oversubscribed 2:1. When the switch is running a single MSM, this module will be oversubscribed 4:1.
Figure 22: G48Pe I/O Module
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 G48Pe 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 G48Pe I/O module has the following LEDs:
● Module status
● Module diagnostics
● Port/Power status
For information about the LEDs and their activity on the G48Pe I/O module, see “I/O Module LEDs”
