• When installing or modifying telephone lines, use caution.

Preventing Electrostatic Discharge Damage

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:

• Ensure that the router chassis is electrically connected to earth ground.

• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted

ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard against ESD damage and shocks, the wrist strap and cord must operate effectively.

• If no wrist strap is available, ground yourself by touching a metal part of the chassis.

Caution For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. It

should be between 1 and 10 Mohm.

Prerequisites

Before installing the Cisco ASR 901 router, it is important to prepare for installation by:

• Preparing the site (site planning) and reviewing the installation plans or method of procedures

• Unpacking and inspecting the Cisco ASR 901 router.

• Gathering tools and test equipment required to properly install the Cisco ASR 901 router.

Site Planning

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 Determine the location of any existing routers and their interconnections, including communications and power. Following the air flow guidelines (see the adequate cooling air is provided to the router.

Power Supply Considerations

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

Warning

This equipment is designed for connection to TN and IT power systems.

Site Environment

Install the Cisco ASR 901 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:

• Ensure that the room where your router operates has adequate air circulation. Electrical equipment

generates heat. Without adequate circulation, ambient air temperature may not cool the equipment to acceptable operating temperatures.

• Always follow ESD-prevention procedures described in the “Preventing Electrostatic Discharge

Damage” section on page 2-3 to avoid damage to equipment. Damage from static discharge can

cause immediate or intermittent equipment failure.

Chapter 2 Preparing to Install the Router

Air Flow Guidelines

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.

Caution If air flow through the equipment rack and the routers that occupy it is blocked or restricted, or if the

ambient air being drawn into the rack is too warm, an over temperature condition can occur within the rack and the routers that occupy it.

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:

• Mount the Cisco ASR 901 router in a 19-inch rack (with a 17.5- or 17.75-inch opening).

• Beside air flow, you must 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 that is generated by equipment near the bottom of the rack can be drawn upward into the intake ports of the equipment above.

Site Planning

• When mounting a chassis in an open rack, ensure that the rack frame does not block the intakes or

(on the left side of the chassis) or the exhaust (on the right side of the chassis).

• When a rack-installed equipment fails, especially equipment in an enclosed rack, try making the

equipment operate by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to give the router a maximum of cooling air and clean power.

Method of Procedure

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.

2. Assign personnel.

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. On an equipment plan, make a preliminary decision that locates each Cisco ASR 901 router that you

plan to install.

OL-23778-01

10. Verify the list of replaceable parts for installation (screws, bolts, washers, and so on) so that the parts

are identified.

Console Port Considerations

The Cisco ASR 901 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 The Cisco ASR 901 router uses only console port.

Note Console and rollover cables are not included with the Cisco ASR 901 router. You can order the console

cable from Cisco Systems, Inc. (Part number ACS-1900ASYN=).

Console Port Connections

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 As a console port, hardware flow control is not supported. For instructions on installing a console terminal, see the

Mounting the Cisco ASR 901 Router

Each Cisco ASR 901 router includes rack-mounting brackets. Using the rack-mounting brackets, you can front-mount theCisco ASR 901 router in a 19-inch (48.3-cm) equipment rack that conforms to the EIA-310-D specification (the inside width of the rack should be 17.72 to 17.80 inches [45 to 45.21 cm]).

Using the two rack-mounting brackets for mounting (part number 700-33522-01), you can recess Cisco

ASR 901 router in the equipment rack. This arrangement provides extra space in front of the router

for the cables and allows you to close the doors of racks equipped with front-close doors.

If you need to attach or replace the rack-mounting brackets, see the “Attaching the Rack-Mounting

Brackets” section on page 3-3.

The rack-mounting brackets are slotted to allow the router to be mounted in racks with EIA 1.25-inch (3.175-cm) or WECO 1.0-inch (2.54-cm) hole spacing. When installed in the rack, the Cisco router requires one EIA 1.75-inch (4.4-cm) vertical mounting space (or 1 rack unit [RU]) for mounting (see the

Caution Allow clearance on either side of the Cisco ASR 901 router for cooling air to be drawn in through the

left side and circulated through the chassis and out the two fan exhaust ports mounted on the other side of the chassis.

Chapter 3 Installing the Cisco ASR 901 Mobile Wireless Router

ASR 901

Rack-Mounting Configuration Guidelines

Follow these guidelines to configure the equipment rack:

• When mounting the router to an equipment rack, ensure that the rack is bolted to the floor.

• Because you may install more than one router into the rack, ensure that the weight of all of the

routers installed does not make the rack unstable.

Caution Some equipment racks are also secured to ceiling brackets, if necessary, due to the weight of the

equipment in the rack. Make sure that the rack you are using to install the routers is secured to the building structure.

• As mentioned in the “Air Flow Guidelines” section on page 2-5, maintain a 6-inch (15.24-cm)

clearance on each side of the router to ensure adequate air intake and exhaust.

• Avoid installing the routers in an overly congested rack. Air flowing to or from other routers in the

rack might interfere with the normal flow of cooling air through the routers, increasing the potential for overtemperature conditions within the routers.

• Allow at least 19 inches (48.7 cm) of clearance at the front and rear of the rack for router

maintenance.

• Follow your local practices for cable management. Ensure that cables to and from the routers do not

impede access to perform equipment maintenance or upgrades.
