Reset Button

The actuation of the Reset button is only recognized during Rommon boot, that is, as the router comes to the
Rommon prompt.
The Reset button does not require much force to be actuated. The Reset button should be actuated only with
a small implement such as the tip of a pen or a paper clip. When the Reset button is pressed at startup, the
system LED will turn green.
For more information, see the "Reset Overview" section of the Cisco 1100 Series Software Configuration
Guide.
Slots and Interfaces

About Slots, Subslots, and Port Numbering

Cisco 1100 Series ISRs do not support physical and removable modules. It has only one slot, that is, slot 0.
Slot 0 is the motherboard and not removable. It is reserved for integrated ports. The front panel GE ports (or
native interface ports) always reside in slot 0 and bay 0. The ports are called Gigabitethernet 0/0/0 and
Gigabitethernet 0/0/1.
Each interface type has its own 'bay', and port is a unique port of an interface type.
In most cases, the router designates its interfaces using a 3-tuple notation that lists the slot, bay, and port. The
3-tuple value is zero based. An example of a 3-tuple is 0/1/2. This refers to slot 0, the second bay in slot 0
(the first bay is 0 so the second bay is 1), and the third port in bay 1. See this section for more examples.
