Enterasys Xpedition 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.
Table 3. Status LEDs
LED Label Description
OK When this LED is on, the XP-2000 and all expansion modules are

XP-2000’s boot PROM to reboot the router.
HBT This LED flashes when the XP-2000’s boot PROM is active.
