Alpine 3800 Series I/O Modules
LEDs
When the I/O module and its ports are configured and operating normally, the front-panel LEDs
should appear as follows:
• STATUS LED—green
• DIAG LED (WM-4Ti module only)—off
• Port status LED (per port):
— Green (all modules except WM-4T1i)
— Alternating green and amber (WM-4Ti1 module only)
If you have installed a PoE I/O module (FM-32Pi) and its ports are configured and operating normally,
the LEDs should appear as follows:
• INT POWER—green
• STATUS—green
For more information about I/O module LED activity, see "I/O Module LEDs" on page 202.
Displaying Slot Status Information
Assuming the I/O module has no problems, the
number of the slot where you installed the module) displays information about the module including:
• General information about the module (name, serial number, part number)
• State of the module (power down, operational, mismatch between the slot configuration and the
module in the slot)
• Status of the ports on the module
For more information about slot status information, see the ExtremeWare Software User Guide and the
ExtremeWare Command Reference Guide.
Installing External Power
The Extreme Networks External Power Supply 45019 (EPS-LD) provides additional power to compatible
Power over Ethernet (PoE) modules and other Extreme switches. The EPS-LD provides 465 W total
power with 375 W dedicated for PoE applications. See the section that describes the connected device to
determine total available power to PoE ports. For detailed installation information, see "Installing the
Alpine 3800 Series Switch External Power Supply" on page 171.

remove a module.
You need the following tools and equipment to remove an I/O module:
• ESD-preventive wrist strap
