Enterasys Networks XSR-1850 Mini-Gigabit Interface Converter MGBIC fiberoptic port plus two LEDs

•Three 10/100/1000BaseT GigabitEthernet LAN ports with two LEDs on each port, instead of the two 10/100BaseT FastEthernet LAN ports

•Mini-Gigabit Interface Converter (MGBIC) fiberoptic port plus two LEDs

•Two NCC slots with two NIM slots on each card

•No power switch

•No default configuration button

All of these physical ports are separated into logical interfaces defined by FIPS 140-2, as described in Table 3:

Module Physical Ports	FIPS 140-2 Logical Interface
Network ports	Data input interface
Network ports	Data output interface
Network ports, console port,	Control input interface
power switch (XSR-18xx only),
default button (XSR-18xx only)
Network ports, console port,	Status output interface
LEDs
Power connector(s)	Power interface

Table 3 – FIPS 140-2 Logical Interfaces

Data input and output, control input, and status output are defined as follows:

•Data input and output are the packets that use the firewall, VPN, and routing functionalities of the modules.

•Control input consists of manual control inputs for power and reset through the power and reset switch. It also consists of all of the data that is entered into the module while using the management interfaces.

•Status output consists of the status indicators displayed through the LEDs and the status data that is output from the modules while using the management interfaces.

The modules distinguish between different forms of data, control, and status traffic over the network ports by analyzing the packets header information and contents.
