Chapter 2 Preparing to Install the Router
General Site Requirements
–
If possible, send another person to get medical aid. Otherwise, determine the condition of the
victim and then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
General Site Requirements
You can mount the Cisco MWR 1900 router in a 19-inch rack (with a 17.5- or 17.75-inch opening).
The following information will help you plan your equipment rack configuration:
• Allow clearance around the rack for maintenance.
• Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each
router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports
of the equipment above.
• When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or
exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated
into the rack.
• Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through
the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can
be found by experimenting with different configurations.
• When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the
equipment by itself, if possible. Power OFF other equipment in the rack (and in adjacent racks) to
allow the router under test a maximum of cooling air and clean power.
Required Tools and Equipment for Installation and Maintenance
You need the following tools and equipment to install and upgrade the router and its components:
• Number 2 Phillips screwdriver
• Screws to fit your rack
• Cables for connection to the WAN and LAN ports (dependent on configuration)
• Ethernet hub or PC with a network interface card for connection to the Ethernet (LAN) port(s).
• Console terminal (an ASCII terminal or a PC running terminal emulation software) configured for
9600 baud, 8 data bits, no parity, and 2 stop bits.
• Modem for connection to the auxiliary port for remote administrative access (optional).
• Console cable for connection to the console port. You can supply this cable yourself or order one
from Cisco (PN ACS-1900ASYN=).
• Terminal block connector (Phoenix part number 1754465).
• Ratcheting torque screwdriver with a Phillips head that exerts up to 15 pound-force inches (lbf-in)
of pressure.
• Panduit crimping tool with optional controlled cycle mechanism, model CT-700, CT-720, CT-920,
CT-930, CT-920CH, or CT-940CH.
• 6-gauge copper ground wire (insulated or noninsulated).
