Enterasys X-Pedition 2000 Getting Started Guide 9
Hardware Overview
External Controls
The XP-2000 has the following external controls. Where appropriate, this guide describes how to
use the controls.
• A Male DB-9 Data Communications Equipment (DCE) port for serial connection from a
management terminal. Use this port to establish a direct CLI connection to the
XP-2000. The default baud rate is 9600.
• A 10Base-T/100Base-TX Data Terminal Equipment (DTE) port for network connection from a
management terminal. The port is configured as Media Data Interface (MDI). Use this port to
establish a management connection to the XP-2000 over a local or bridged Ethernet segment.
• A Reset switch (RST). Use this switch to reboot the XP-2000’s motherboard from the internal
boot flash in the event of a system failure. The Reset switch is recessed in the XP-2000’s chassis,
so you will have to use a tool like a small allen wrench to activate the switch.
• Status LEDs.
Motherboard Features
The internal “motherboard” performs all the XP-2000’s computing and routing functions. It
contains system-wide bridging and routing tables. Traffic that does not yet have an entry in the L2
and L3/L4 lookup tables on individual expansion modules is handled by the motherboard. After
processing traffic, the motherboard updates the L2 and L3/L4 tables on the ports and/or expansion
slot(s) that received the traffic. The ports/expansion slot(s) thus “learn” about how to forward
traffic.
Boot Flash
The motherboard has a boot flash containing the XP-2000’s boot software and configuration files.
The system software image file resides on an internal flash chip and can be upgraded from a TFTP
server.
