Appendix C: Hardware Specifications
•
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 an SNMP connection to the IA 1100/1200 over a local or bridged
Ethernet segment.
•
A Reset switch (RST). Use this switch to reboot the IA 1100/1200's motherboard from
the internal boot flash in the event of a system failure. The Reset switch is recessed in
the IA 1100/1200's chassis, so you will have to use a tool like a small allen wrench to
activate the switch.
•
System switch (SYS). This switch stops the system software and starts the debugger.
Normally, you should not use this switch unless directed to do so by Cabletron Systems
personnel.
•

Motherboard Features
The internal "motherboard" performs all the IA 1100/1200'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 Gigabit ports is handled by
the motherboard. After processing traffic, the motherboard updates the L2 and L3/L4
tables on the Gigabit ports that received the traffic. The Gigabit ports thus "learn" about
how to forward traffic.
Boot Flash
The motherboard has a boot flash containing the IA 1100/1200'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.

When this LED is on, the IA 1100/1200 and all Gigabit ports are
functioning correctly.
When this LED is on, a fatal system error has occurred. Activate the IA
1100/1200's boot PROM to reboot the router.
This LED flashes when the IA 1100/1200's boot PROM is active.
When this LED is on, the IA 1100/1200 is in diagnostic mode. (While in
diagnostic mode, several other LEDs on the IA 1100/1200 are active as
well.)
