Installation prerequisites and preparation information for installing an uplink card in a Cisco 10720
router are in the following sections:
•
Hardware Requirements, page 2-1
•
Software Requirements, page 2-2
•
Safety and Compliance, page 2-3
Hardware Requirements
Ensure that your equipment configuration meets the minimum requirements for the uplink card
installation and that you have all the parts and tools you need.
To ensure compatibility with the Cisco IOS software, your DPT or POS/DPT uplink card should have a
hardware revision level of 73-05345-03 Rev. A0 or higher. Your RPR/SRP uplink card should have a
hardware revision level of 73-9006-02 Rev. A0 or higher. Determine the hardware revision number by
using the following method:
•
Hardware label
Read the hardware revision number printed on a label affixed to the component side of the
uninstalled card.
•
show diags 1 slot command
Use the show diags 1 slot command to identify an installed uplink card. See the following example
to locate the hardware revision for the uplink card. In the example below, see the lines called out in
italic print to indicate where the hardware revision number is located.

Preparing for Installation
Safety and Compliance
Safety and Compliance
Before you begin any of the procedures in this publication, review the safety and compliance guidelines
in the following sections to avoid injuring yourself or damaging the equipment:
•
Safety Information and Electromagnetic Compliance, page 2-3
•
Safety Warnings, page 2-3
•
Disconnect Device Warning, page 2-3
•
Laser Safety, page 2-4
•
Preventing Electrostatic Discharge, page 2-4
Safety Information and Electromagnetic Compliance
For information about regulatory compliance and safety, refer to the Regulatory Compliance and Safety
Information for the Cisco 10720 Internet Router publication that is shipped with your device, and
information in the “Electromagnetic Compliance” section on page ix of this document. This publication
contains important safety information that you must read and understand before attempting to install,
remove, or modify any hardware in your router.
For more information about safety and electromagnetic compliance, see the “Translated Safety
Warnings” section on page x and the “Electromagnetic Compliance” section on page ix.
Safety Warnings
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, can
harm you. A warning symbol precedes each warning statement. The following paragraph is an example
of a safety warning:
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work
on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with
standard practices for preventing accidents. To see translations of the warnings that appear in this
publication, refer to the Regulatory Compliance and Safety Information for the
Cisco 10720 Internet Router document that accompanied this device.
For safety warning translations, see the “Translated Safety Warnings” section on page x.
Disconnect Device Warning
Disconnect the Cisco 10720 Internet Router power source before performing any maintenance task on
the hardware modules.
Warning
Only trained and qualified personnel should be allowed to install or replace this equipment.
Warning
The plug-socket combination must be accessible at all times because it serves as the main
disconnecting device.

Safety and Compliance
Warning
This unit might have more than one power cord. To reduce the risk of electric shock, disconnect
the two power supply cords before servicing the unit
Warning
Incorporate a readily accessible two-poled disconnect device into the fixed wiring.
Warning
An on or off switch or a disconnect device is not provided on this product with direct current (DC)
power. A readily accessible disconnect device, such as a circuit breaker, shall be incorporated
into the fixed wiring.
Laser Safety
The RPR/SRP, DPT, and POS/DPT uplink cards are equipped with a Class 1 laser that emits invisible
radiation. Do not stare into open ports on the uplink card. Laser safety includes the following warnings:
Warning
•
Class 1 Laser Product Warning
•
Class 1 LED Product Warning
Avoid exposure to laser radiation. Do not stare into an open apertures, because invisible laser
radiation may be emitted from the aperture when a cable is not inserted in the port.
Class 1 Laser Product Warning
Warning

For translated Class 1 LED warnings, refer to the Regulatory Compliance and Safety Information for the
Cisco 10720 Internet Router publication.
Preventing Electrostatic Discharge
Electrostatic discharge (ESD) damage can occur when electronic cards or components are improperly
handled. This will cause complete or intermittent failures. We recommend using an ESD-preventive
strap when you handle a router or one of its components. Electromagnetic interference (EMI) shielding
is an integral component of the router.

Chapter 2
Preparing for Installation
Safety and Compliance
Following are guidelines for preventing ESD damage:
Caution
•
Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the connection cord to bare metal on the router chassis. (See
Figure 2-1.)
•
Attach an ESD-preventive wrist strap to your wrist, and to the chassis or to a bare metal surface.
(See Figure 2-1.)
•
The wrist strap protects equipment from ESD voltages on the body only; ESD voltages on clothing
can still cause damage to electronic components.
To avoid ESD damage to the equipment, periodically check the resistance value of the
ESD-preventive wrist strap. The resistance measurement should be between 1 and 10 megohms
(Mohms).

•
When installing the card, confirm that the card is fully seated in the midplane and tighten the
spring-loaded screws. These screws prevent accidental removal, provide proper grounding for the
system, and help ensure that the connectors are seated in the midplane. (See Figure 2-1 and the
“Figure 3-6Disconnecting the Optical Interface Cable” section on page 3-6.)
•
When removing the card, use the spring-loaded screws to unseat the card connector from the
midplane. (See Figure 3-10 and the “Figure 3-6Disconnecting the Optical Interface Cable” section
on page 3-6.)
•
Handle the card by the spring-loaded screws only; avoid touching the board or connector pins.
•
Place the card board-side-up on an antistatic surface or in a static shielding bag. If you plan to return
the card to the factory, immediately place it in a static shielding bag.
•
Avoid contact between the card and clothing. The wrist strap protects the board only from ESD
voltages on the body; ESD voltages on clothing can still cause damage.
