Maintaining Safety with Electricity
Maintaining Safety with Electricity
Warning Before working on a chassis or working near power supplies, unplug the power cords on an
AC-powered system. On a DC-powered system, disconnect the power at the circuit breakers.
Follow these guidelines when working on equipment powered by electricity:
•Locate the emergency power-off switch for the room in which you are working. If an electrical
accident occurs, you can quickly turn off the power.
•Do not work alone if potentially hazardous conditions exist anywhere in your workspace.
•Never assume that power is disconnected from a circuit—Always check the circuit.
•Carefully look for possible hazards in your work area, such as moist floors, ungrounded power
extension cords, or missing safety grounds.
•If an electrical accident occurs:
– Use caution—Do not let yourself become a victim.
– Disconnect power from the system.
– If possible, send another person to get medical aid. Otherwise, assess the condition of the victim
then call for help.
•Use the Cisco MGX 8850 AC and MGX 8850 DC systems within their marked electrical ratings and
product usage instructions.
•Install the Cisco MGX 8850 AC or MGX 8850 DC systems with the following local, national, or
international electrical codes:
– United States—National Fire Protection Association (NFPA70), United States National
Electrical Code.
– Canada—Canadian Electrical Code, Part 1, CSA C22.1.
– Other countries—International Electromechanical Commission (IEC) 364, Part 1 through
Part 7.
•Cisco MGX 8850 AC models are shipped with a 3-wire electrical cord with a grounding-type plug
that fits only a grounding type power outlet. This is a safety feature that you should not circumvent.
Equipment grounding should comply with local and national electrical codes.
•Cisco MGX 8850 DC models are equipped with DC power entry modules and require you to
terminate the DC input wiring on a DC source capable of supplying at least 60A. A 60A circuit
breaker is required at the 48 VDC facility power source. An easily accessible disconnect device
should be incorporated into the facility wiring. Be sure to connect the grounding wire conduit to a
solid earth ground. A closed loop ring is recommended to terminate the ground conductor at the
ground stud.
•Other DC power guidelines are as follows:
– Only a DC power source that complies with the safety extra low voltage (SELV) requirements
of UL 1950, CSA C22.2 No. 950-95, EN 60950 and IEC 950 can be connected to a Cisco MGX
8850 DC-input power entry module.
– Cisco MGX 8850 DC which is equipped with DC power entry modules is intended only for
installation in a restricted access location. In the United States, a restricted access area is in
accordance with Articles 110–16, 110–17, and 110–18 of the National Electrical Code

General Site Requirements
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when
electronic components are improperly handled and can result in complete or intermittent failures.
Always follow ESD prevention procedures when removing and replacing components. Ensure that the
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 safely channel
unwanted ESD voltages to ground. To properly guard against ESD damage and shocks, the wrist strap
and cord must operate effectively. If no wrist strap is available, ground yourself by touching the metal
part of the chassis.
Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and
10 megohms (Mohms).
General Site Requirements
This section describes the requirements your site must meet for safe installation and operation of your
system. Ensure that your site is properly prepared before beginning installation.
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.
Warning The Cisco MGX 8850 and RPM-XF are designed to work with TN power systems.
The AC power supply of the RPM-XF is part of the Cisco MGX 8850 chassis. The RPM-XF, when
installed in the Cisco MGX 8850 chassis, receives –48 volts DC power from the midplane.
The DC power supply of the RPM-XF is part of the Cisco MGX 8850 chassis. The RPM-XF, when
installed in the Cisco MGX 8850 chassis, receives –48 volts DC power from the midplane.
The RPM-XF is installed in the Cisco MGX 8850 chassis. Refer to the Cisco MGX 8850 Routing Switch
Installation Guide. The location of the Cisco MGX 8850 chassis and the layout of your equipment rack
or wiring room are extremely important for proper system operation. Equipment placed too close
together, inadequate ventilation, and inaccessible panels can cause system malfunctions and shutdowns,
and can make RPM-XF maintenance difficult.

Preparing to Connect to a Network
When setting up your RPM-XF in the Cisco MGX 8850, consider distance limitations and potential
electromagnetic interference (EMI) as defined by the EIA.
Note The Fast Ethernet, console, and auxiliary ports contain safety extra-low voltage (SELV) circuits.
Connect them only to SELV-circuit equipment.
Ethernet Connection
The Ethernet ports located on the MGX-XF-UI or MGX-XF-UI/B back card support IEEE Ethernet
standard 802.3 and Fast Ethernet standard 802.3u. The back card implementation supports the following
connections:
•10BASE-T— Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is
328 feet (100 meters). UTP cables look like wiring used for ordinary telephones; however, UTP
cables meet certain electrical standards that telephone cables do not. The 10BASE-T Ethernet
operates at 10Mbs and can be connected through the RJ-45 connector.
•100BASE-TX—100BASE-T Ethernet, half and full duplex over Category 5 UTP, Electronics
Industry Association and Telecommunications Industry Association [EIA/TIA]-568-compliant
cable. The 100BASE-T Ethernet operates at 100Mbs and can be connected through the RJ-45
connector.
The cables required to connect the MGX-XF-UI or MGX-XF-UI/B Fast Ethernet ports to an Ethernet
network are not included. For cable ordering information, contact customer service.
For cable and port pinouts, see Appendix B, “Cable and Connector Specifications.”
Console and Auxiliary Ports
The MGX-XF-UI and MGX-XF-UI/B include asynchronous serial console and auxiliary ports. The
console and auxiliary ports provide local administrative access to the RPM-XF. This section discusses
important cabling information to consider before connecting a console terminal to the console port or
the auxiliary port.

Chapter 2 Preparing to Install the MGX RPM-XF
Preparing to Connect to a Network
The main difference between the console and auxiliary ports is that the auxiliary port supports hardware
flow control and the console port does not. Flow control paces the transmission of data, ensuring that the
receiving device can absorb the data sent to it before the sending device sends more. When the buffers
on the receiving device are full, a message is sent to the sending device to suspend transmission until the
data in the buffers has been processed.
Console Port Connection
The MGX-XF-UI and MGX-XF-UI/B include an EIA/TIA-232 asynchronous serial console port
(RJ-45). This port will appear as a DTE device at the end of the cable.
Note We do not provide console cables in the MGX-RPM-XF-512, MGX-XF-UI, or MGX-XF-UI/B kit.
Console cables can be ordered as spares from Cisco Systems.
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 console port are 9600 baud, 8 data bits, no parity, and 1 stop
bit.
The console port does not support hardware flow control. For detailed information about installing a
console terminal, see Chapter 3, “Installing the MGX RPM-XF Front and Back Cards.” For cable and
port pinouts, see Appendix B, “Cable and Connector Specifications.”
Auxiliary Port Connections
The RPM-XF includes an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow
control. This port will appear as a DTE device at the end of the cable.
Note Connecting a modem to the auxiliary port on the MGX-XF-UI or MGX-XF-UI/B is not supported.
Note We do not provide console cables in the MGX-RPM-XF-512, MGX-XF-UI, or MGX-XF-UI/B kit.
Console cables can be ordered as spares from Cisco Systems.
For detailed information about connecting devices to the auxiliary port, see Chapter 3, “Installing the
MGX RPM-XF Front and Back Cards.” For cable and port pinouts, see Appendix B, “Cable and
Connector Specifications.”
