Chapter 2 Installation Safety and Site Preparation
Safety with Electricity
Follow these guidelines when working on equipment powered by electricity:
• Locate the emergency power-off switch in the room in which you are working. If an electrical
accident occurs, you can quickly turn off the power.
• Disconnect all power before doing the following:
–
Installing or removing a chassis
–
Working near power supplies
• Look carefully for possible hazards in your work area, such as moist floors, ungrounded power
extension cables, frayed power cords, and missing safety grounds.
• Do not work alone if hazardous conditions exist.
• Never assume that power is disconnected from a circuit. Always check.
• Never open the enclosure of the router’s internal power supply.
• If an electrical accident occurs, proceed as follows:
–
Use caution; do not become a victim yourself.
Safety Recommendations
–
Turn off power to the device.
–
If possible, send another person to get medical aid. Otherwise, assess the victim’s condition and
then call for help.
–
Determine if the person needs rescue breathing or external cardiac compressions; then take
appropriate action.
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity.
Statement 1001
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It can occur if
electronic printed circuit cards are improperly handled and can cause complete or intermittent failures.
Always follow ESD prevention procedures when removing and replacing modules:
• Ensure that the router chassis is electrically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the clip to
an unpainted surface of the chassis frame to channel unwanted ESD voltages safely to ground. To
guard against ESD damage and shocks, the wrist strap and cord must operate effectively.
• If no wrist strap is available, touch a metal part of the chassis to discharge any electromagnetic build
up.
OL-26438-01
CautionFor the safety of your equipment, periodically check the resistance value of the antistatic strap. It should
This section describes the requirements your site must meet for safe installation and operation of your
router. Ensure that the site is properly prepared before beginning installation. If you are experiencing
shutdowns or unusually high errors with your existing equipment, this section can also help you isolate
the cause of failures and prevent future problems.
Rack Mounting
The router is designed for mounting on a DIN rail, or a wall. Cisco recommends that the router not be
rack mounted. However, if you install the router in a rack, follow these guidelines:
• Allow clearance around the rack for maintenance.
• Allow at least one rack unit of vertical space between routers.
• 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.
Chapter 2 Installation Safety and Site Preparation
Router Environmental Requirements
The location of your router and the layout of the substation environment are important considerations
for proper router operation. Equipment placed too close together, inadequate ventilation, and
inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult.
Install the router so that you can access both the module-side and the cable-side panels.
When planning your site layout and equipment locations, refer to General Site Requirements, page 2-4.
If you are currently experiencing shutdowns or an unusually high number of errors with your existing
equipment, these precautions and recommendations may help you isolate the cause of failure and prevent
future problems.
• Ensure that the room where your router operates has adequate air circulation. Electrical equipment
generates heat. Without adequate air circulation, ambient air temperature may not cool equipment
to acceptable operating temperatures.
• Always follow ESD-prevention procedures described in Preventing Electrostatic Discharge
Damage, page 2-3, to avoid damage to equipment. Damage from static discharge can cause
immediate or intermittent equipment failure.
• Ensure that the chassis cover and module cable side panels are secure. All empty module slots and
power supply bays must have filler panels installed.
• 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.
Power Guidelines and Requirements
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.
Chapter 2 Installation Safety and Site Preparation
The AC power supply includes the autoselect feature for either 110 V or 220 V operation.
Network Cabling Specifications
The following sections describe the cables needed to install the router:
• Preparing for Network Connections, page 2-5
• Preparing for Network Connections, page 2-5
Preparing for Network Connections
When setting up your router, consider distance limitations and potential electromagnetic interference
(EMI) as defined by the applicable local and international regulations.
Network connection considerations are provided for several types of network interfaces and are
described in the following sections:
• Ethernet Connections, page 2-5
Network Cabling Specifications
• Serial Connections, page 2-5
Ethernet Connections
The IEEE has established Ethernet as standard IEEE 802.3. The router supports the following Ethernet
implementations:
• 1000BASE-X—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded
• 1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded
• 100BASE-TX—100 Mb/s full-duplex transmission over a Category 5 or better unshielded
Serial Connections
The router supports serial connections on the serial ports. Before you connect a device to a serial port,
you need to know the following:
• Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are
• Type of connector, male or female, required to connect to the device

• Signaling standard required by the device
Configuring Serial Connections
The router serial ports user a supported cable with a DB-25 connector. Serial ports can be configured as
DTE or DCE, depending on the serial cable used.
A device that communicates over a synchronous serial interface is either a DCE or DTE device. A DCE
device provides a clock signal that paces the communications between the device and the router. A DTE
device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation
that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a
jumper to select either DTE or DCE mode.) Tab le 2-1 lists typical DTE and DCE devices.

Signaling Standards Supported
The synchronous serial ports available for the router support the following signaling standards:
EIA/TIA-232 (EIA-323). You can order a Cisco DB-25 shielded serial transition cable that has the
appropriate connector for the standard you specify. The documentation for the device should indicate the
standard used for that device. The router end of the shielded serial transition cable has a DB-25
connector, which connects to the DB-25 port on the router. The other end of the serial transition cable is
available with a connector appropriate for the standard you specific.
The synchronous serial port can be configured as DTE or DCE, depending on the attached cable.
All serial ports configured as DTE require external clocking from a CSU/DSU or other DCE device.
Distance Limitations
Serial signals can travel a limited distance at any given bit rate; generally, the slower the data rate, the
greater the distance. All serial signals are subject to distance limits, beyond which a signal significantly
degrades or is completely lost.
Table 2-2 lists the recommended maximum speeds and distances for each serial interface type; however,
you might get good results at speeds and distances greater than those listed, if you understand the
electrical problems that might arise and can compensate for them. For instance, the recommended
maximum rate for V.35 is 2 Mb/s, but 4 Mb/s is commonly used.

inside substations or utility cabinets. This platform is built to meet the communication infrastructure
needs of electric, gas, and water utilities.
The router provides an end-to-end communication network that enables increased power grid efficiency
and reliability, reduced energy consumption, and reduced greenhouse gas emissions. The router also
enables distributed intelligence for converged smart grid applications, including:
• Integration of Distributed Energy Resources (DER)
• Remote workforce automation
The router provides reliable and secure real-time communication between network systems and the many
devices that exist on the distribution grid, including meters, sensors, protection relays, Intelligent
Electronic Devices (IEDs), plug-in electric vehicle (PEV) charging stations, and distributed solar farms.
Network data is forwarded and processed over secure communication links between devices within the
distribution grid for local decision processing.
Additionally, this data is sent to Supervisory Control and Data Acquisition (SCADA) systems and other
management systems. The router supports physical connection to legacy distribution automation (DA)
devices (over the serial port); the data from these devices can also be sent to central SCADA systems
using protocol translation over the IP network.
