Before installing and connecting a Cisco 4000 Series Integrated Services Router, read the safety
warnings and gather the following tools and equipment.
• ESD-preventive cord and wrist strap
• Number 2 Phillips screwdriver
• Flat-blade screwdrivers: small, 3/16-in. (4 to 5 mm) and medium, 1/4-in. (6 to 7 mm)
– To install or remove modules
– To remove the cover, if you are upgrading memory or other components
• Screws that fit your rack
• Wire crimper
• Wire for connecting the chassis to an earth ground:
– AWG 6 (13 mm) wire for NEBS-compliant chassis grounding
– AWG 14 (2 mm) or larger wire for NEC-compliant chassis grounding
– AWG 18 (1 mm) or larger wire for EN/IEC 60950-compliant chassis grounding
• For NEC-compliant grounding, an appropriate user-supplied ring terminal, with an inner diameter
of 1/4 in. (5 to 7 mm)
In addition, depending on the type of modules you plan to use, you might need the following equipment
to connect a port to an external network:
• Cables for connection to the WAN and LAN ports (dependent on configuration)
Note For more information on cable specifications, see the Cisco Modular Access Router Cable
Specifications document at cisco.com.
• Ethernet hub or PC with a network interface card for connection to an Ethernet (LAN) port.
• Console terminal (an ASCII terminal or a PC running HyperTerminal or similar terminal emulation
software) configured for 9600 baud, 8 data bits, 1 stop bit, no flow control, and no parity.
• Modem for connection to the auxiliary port for remote administrative access (optional).
• Data service unit (DSU) or channel service unit/data service unit (CSU/DSU) as appropriate for
serial interfaces.
• External CSU for any CT1/PRI modules without a built-in CSU.
Also, you need to have access to the following:
CLI Console Access
Use the USB or RJ-45 console port on the router to access the Cisco Internet Operating System
(IOS-XE) command line interface (CLI) on the router and perform configuration tasks. A terminal
emulation program is required to establish communication between the router and a PC. See the
“Connect to Console Terminal or Modem” section on page 3-22 for instructions.
Note A Microsoft Windows USB driver must be installed before you establish physical connectivity
between the router and the PC.
