Installing the Router
Ethernet Devices
Identify the Ethernet devices that you will connect to the router: hub, servers, and workstations or PCs.
Ensure that each device has a network interface card (NIC) for connecting to Ethernet ports.
If you plan to configure the software using Cisco IOS commands through the console port, provide an
ASCII terminal or a PC that is running terminal emulation software to connect to the console port.
If you plan to connect a modem, provide the modem and modem cable.
Installing the Router
This section describes how to install the Cisco 819 ISR. These routers can be installed on a table top or
other flat horizontal surface mounted on a wall or DIN rail.
The recommended clearance when horizontally mounted is 1.5 inches on both sides for floor mount
bracket clearance and 2 inches on top. Top clearance is not required but stacking heat-dissipating objects
on top of the router is not allowed. I/O side clearance is needed as it is required to access the cable
connections. Clearance is not required on the backside (opposite side from I/O face) unless DIN rail
mounting is required. Clearance is required to attach and mount the DIN rail bracket. The same
clearances apply when mounted vertically.
