When working on electrical equipment, follow these guidelines:
– Working on or near power supplies.
– Installing or removing a router chassis, or network processor module.
– Performing most hardware upgrades.
– Use caution, and do not become a victim yourself.
– Switch off power to the router.
– If possible, send another person to get medical aid. Otherwise, determine the condition of the victim, and then call for help.
– Determine whether the person needs rescue breathing or external cardiac compressions; then take appropriate action.
In addition, use the following guidelines when working with any equipment that is disconnected from a power source, but still connected to telephone wiring or network cabling:
Electrostatic Discharge (ESD) can damage equipment and impair electrical circuitry. ESD can occur when electronic printed circuit cards are improperly handled, and can cause complete or intermittent failures. When removing and replacing modules, always follow ESD prevention procedures:
Before installing the Cisco ASR 901 10G router, it is important to prepare for installation by:
Ideally, you should have prepared the installation site beforehand. As part of your preparation, obtain a floor plan of the site and the equipment rack where the Cisco ASR 901 10G router would be housed. Determine the location of any existing routers and their interconnections, including communications and power. Following the air flow guidelines (see the “Air Flow Guidelines” section), ensure that adequate cooling air is provided to the router.
All personnel involved in the installation of the router including installers, engineers, and supervisors should participate in the preparation of a Method of Procedure (MOP) for approval by the customer.
Check the power at your site to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary (see the Power Supply for power requirements).
Warning This equipment is designed for connection to TN and IT power systems. Statement 16
Install the Cisco ASR 901 10G router in an equipment rack. The location of your router and the layout of your equipment rack, or wiring room are extremely important considerations for proper operation. Cramped equipment, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdown, and can make maintenance difficult. Plan to access the front and rear panels of the router.
Take the following precautions for an acceptable operating environment for your router and to avoid environmentally caused equipment failures:
– -40 to +149°F (-40°C to +65°C)
Note For an outside plant installation (cell site cabinet, hut, etc.), it is required that the router be protected against airborne contaminants, dust, moisture, insects, pests, corrosive gases, polluted air or other reactive elements present in the outside air. To achieve this level of protection, it is recommended that the unit is installed in a fully sealed (i.e. Closed Loop) enclosure. Examples of such cabinets include IP65 cabinets with heat exchanger, complying with Telecordia GR487.
To ensure adequate air flow through the equipment rack, we recommend that you maintain a clearance of at least 6 inches (15.24 cm) on each side of the rack at all times.
The site should also be as dust-free as possible. Dust tends to clog the router fans, reducing the flow of cooling air through the equipment rack and the routers. Thus, increasing the risk of an over temperature condition.
Use the following guidelines to plan your equipment rack configuration:
Part of site preparation includes reviewing installation plans or method of procedures (MOPs). An example of a MOP that includes pre-installation checklist of tasks, considerations to address and agree upon before proceeding with the installation, is as follows:
1. Read this hardware installation guide.
3. Determine protection requirements for personnel, equipment, and tools.
4. Evaluate potential hazards that may affect service.
5. Schedule time for installation.
6. Determine space requirements.
7. Determine power requirements.
8. Identify required procedures or tests.
9. Make a preliminary plan that locates each Cisco ASR 901 10G router that you plan to install.
10. Verify the list of replaceable parts for installation (screws, bolts, washers, and so on).
11. Check the required tools list to make sure the necessary tools and test equipment are available (see the “Required Tools and Equipment” section).

The Cisco ASR 901 10G router provides a single console port (labeled CONSOLE). A single RJ-45 cable is used for a console connection.
This section describes important cabling information to consider before connecting a console terminal—either an ASCII terminal or a PC running terminal emulation software—or a modem to the console port. The console port provides access to the router either locally (using a console terminal), or remotely (using a modem).
Note Console and rollover cables are not included with the Cisco ASR 901 10G router. You can order the console cable from Cisco Systems, Inc. (Part number ACS-1900ASYN=).
The router provides an EIA/TIA-232 asynchronous serial console port (RJ-45). Depending on the cable and the adapter used, this port appears as a data terminal equipment (DTE) or data communications equipment (DCE) device at the end of the cable.
To connect an ASCII terminal to the console port, use the RJ-45 rollover cable with the female RJ-45-to-DB-25 adapter (labeled TERMINAL). To connect a PC running terminal emulation software to the console port, use the RJ-45 rollover cable with the female RJ-45-to-DB-9 adapter (labeled TERMINAL). The default parameters for the port are 9600 baud, 8 data bits, no parity, and 2 stop bits. As a console port, hardware flow control is not supported. For instructions on installing a console terminal, see the “Connecting the Console Port” section.
For cable and port pinouts, see the online document Cisco Modular Access Router Cable Specifications. This document is provided on the documentation DVD that accompanied your router (if ordered).
