SmartSwitch Router 2100 Getting Started Guide 11
Chapter 1: Features Overview
Use this port to establish a CoreWatch management connection to the SSR 2100 over a
local or bridged Ethernet segment.
• A Reset switch (RST). Use this switch to reboot the SSR 2100’s motherboard from the
internal boot flash in the event of a system failure. The Reset switch is recessed in the
SSR 2100’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.
• Status LEDs, described in the following table:
Motherboard Features
The internal “motherboard” performs all the SSR 2100’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 SSR 2100’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.
Table 3. Status LEDs
LED Label Description
OK When this LED is on, the SSR 2100 and all Gigabit ports are
functioning correctly.
ERR When this LED is on, a fatal system error has occurred. Activate the
SSR 2100’s boot PROM to reboot the router.
HBT This LED flashes when the SSR 2100’s boot PROM is active.
DIAG When this LED is on, the SSR 2100 is in diagnostic mode. (While in
diagnostic mode, several other LEDs on the SSR 2100 are active as
well.)
