Warning
The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low voltage (SELV)
circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like
telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.

Site Preparation and Unpacking
•
Lift the router safely out of the packing container.
•
Ensure the power service at the site is suitable for the router you are installing.
•
Check the packing slip to ensure that all the proper components are present.
•
Locate and have accessible the Site Log for recording information about this installation.
Tools and Parts
Use the following list of tools and parts as a checklist for preparing for installing the Cisco 7301 router:
•
ESD-preventative wrist strap
•
Power cord and AC power cable-retention clip
•
Appropriate cables to connect the router to the network and to the console terminal
•
One serial port adapter cable for each serial port to connect the port with the remote device or network Ethernet transceiver
•
Data service unit (DSU) to connect each serial port to an external network
•
Tape measure and level
•
Screwdrivers: Number 2 Phillips screwdriver and 3/16-inch flat-blade screwdriver
•
Grounding lug and wires:
–
A grounding lug with two number-10 screw holes with a 0.63-inch (16.002-mm) spacing between them
–
A wire receptacle large enough to accept a 6-AWG multistrand, copper wire
–
Two Phillips machine screws with locking washers—M5 (metric), 0.031-inch (.08-mm) pitch, 0.315-inch (8-mm) length
–
A crimping tool to fit the grounding lug wire receptacle
–
One grounding wire—6-AWG, 0.162-inch (4.115-mm) diameter, with approximately 0.108-inch (2.743-mm)
insulation, for a total wire diameter of approximately 0.27 inches (6.858 mm). The wire length depends on your router
location and site environment.

•
The rack-mount and cable-management kit:
–
Two rack-mount brackets and one cable-management bracket
–
Screws: Four 12-24 x 0.5-inch screws, four 8-18 x .37-inch screws for use with a 19-inch rack, four 8 x .375-inch screws
for use in a 21–23-inch rack, and one M4 x 20-mm screw

•
T1 channel service unit/data service unit (CSU/DSU) that converts the High-Level Data Link Control (HDLC) synchronous
serial data stream into a T1 data stream with the correct framing and ones density to connect a serial port to a T1 network.
(Some telephone systems require a minimum number of 1 bits per time unit in a data stream, called ones density.) Several
T1 CSU/DSU devices are available as additional equipment, and most provide a V.35, EIA/TIA-449, or EIA-530 electrical
interface.
