About Slots, Subslots, and Port Numbering
The Cisco 1100 series designates its interfaces using a 3-tuple notation that lists the slot, sub slot and port in
the format slot/sub-slot/port. The slot number is reserved for the mother board, which is "0". Each interface
type is allocated a sub slot and the port number is a unique port on the interface.

Specifications of Cisco 1000 Series Integrated Services Routers
For specifications on the Cisco 1000 Series Integrated Services Routers, refer to the Cisco 1100 Series ISR
Specifications document.
Periodic Inspection and Cleaning
We recommend that you periodically inspect and clean the external surface of the router. Removing is
recommended to minimize the negative impact of environmental dust or debris. The frequency of inspection
and cleaning is dependent upon the severity of the environmental conditions, but we recommend cleaning the
router once every six months. Cleaning involves vacuuming router air intake and exhaust vents.
Sites with ambient temperatures consistently above 25°C or 77°F and with potentially high levels of dust or
debris might require periodic preventative maintenance cleaning.
