Slot Numbering
The Cisco 3600 series router chassis contains two or four slots in which you can install
modules. You can install any module into any available slot in the chassis.
As shown in Figure 1-1 and Figure 1-2, the slots are numbered as follows:
•
Slot 0 is at the bottom right (as viewed from the rear of the chassis), near the power
supply.
•
Slot 1 is at the bottom left.
•
Slot 2 is at the top right, above slot 0.
•
Slot 3 is at the top left, above slot 1.
Some modules have two small slots, labeled W0 and W1, for WAN interface cards.
Figure 1-3 shows the W0 and W1 slots of the 2 Ethernet 2 WAN card slot
(2E 2-slot) module. You can install WAN interface cards into the small module slots (W0
and W1). Serial WAN interface cards can be installed into either slot, W0 or W1.

Unit Numbering
Cisco 3600 series routers unit numbers identify the interfaces on the modules and WAN
interface cards installed in the router. Unit numbers begin at 0 for each interface type, and
continue from right to left and (if necessary) from bottom to top. Modules and WAN
interface cards are identified by interface type, slot number, followed by a forward slash
(/), and then the unit number; for example, Ethernet 0/0.
