Port Adapter Installation Prerequisites

Var ning! Denna varningssymbol signalerar fara. Du befinner dig i en situation som kan leda till

personskada. Innan du utför arbete på någon utrustning måste du vara medveten om farorna med
elkretsar och känna till vanligt förfarande för att förebygga skador. Se förklaringar av de varningar
som förkommer i denna publikation i dokumentet Regulatory Compliance and Safety Information
(Efterrättelse av föreskrifter och säkerhetsinformation), vilket medföljer denna anordning.

Electrical Equipment Guidelines

Follow these basic guidelines when working with any electrical equipment:

• Before beginning any procedures requiring access to the chassis interior, locate the emergency

power-off switch for the room in which you are working.

• Disconnect all power and external cables before moving a chassis; Do not work alone when

potentially hazardous conditions exist.

• Never assume that power has been disconnected from a circuit; always check.

• Do not perform any action that creates a potential hazard to people or makes the equipment

unsafe; carefully examine your work area for possible hazards such as moist floors, ungrounded
power extension cables, and missing safety grounds.

Telephone Wiring Guidelines

Use the following guidelines when working with any equipment that is connected to telephone
wiring or to other network cabling:

• Never install telephone wiring during a lightning storm.

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet

locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been

disconnected at the network interface.

• Use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are
improperly handled, results in complete or intermittent failures. Port adapters and processor modules
consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI)
shielding and connectors are integral components of the carrier. Although the metal carrier helps to
protect the board from ESD, use a preventive antistatic strap during handling.

Following are guidelines for preventing ESD damage:

• Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

• Connect the equipment end of the strap to an unfinished chassis surface.

• When installing a component, use any available ejector levers or captive installation screws to

properly seat the bus connectors in the backplane or midplane. These devices prevent accidental
removal, provide proper grounding for the system, and help to ensure that bus connectors are
properly seated.

• When removing a component, use any available ejector levers or captive installation screws to

release the bus connectors from the backplane or midplane.

6 PA-100VG AnyLAN Port Adapter Installation and Configuration

• Handle carriers by available handles or edges only; avoid touching the printed circuit boards or

connectors.

• Place a removed component board-side-up on an antistatic surface or in a static shielding

container. If you plan to return the component to the factory, immediately place it in a static
shielding container.

• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects

components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should

be between 1 and 10 megohms.

What Is the 100VG Port Adapter?

This section contains information specific to the 100VG port adapter and its use with Cisco 7000
series, Cisco 7200 series, and Cisco 7500 series routers.

The following sections discuss information specific to the 100VG port adapter:

What Is the 100VG Port Adapter?

• 100VG Port Adapter LEDs, page 8

• 100VG Port Adapter Interface Receptacles, Cables, and Pinouts, page 9

• Port Adapter Locations on the VIP2 and in the Cisco 7200 Series Router, page 9

Each 100VG port adapter provides a single interface ports, which is compatible with and specified
by IEEE 802.12, to provide 100-Mbps interface over Category 5, unshielded twisted-pair (UTP)
cable (with RJ-45 connectors), supporting 802.3 Ethernet packets. The 100VG port adapter operates
at 120 Mbps with a 5B/6B coding scheme, which provides a data rate of 100 Mbps.

Note The 100VG interfaces on a 100VG port adapter can be configured at 100 Mbps, half duplex

for a maximum aggregate bandwidth of 100 Mbps per 100VG interface.

The 100VG port adapter is designed to conform to the following emissions standards: FCC Part 15
Class A, Cispr22 Class A, EN 55022 Class A, and VCCI Class 1.

The PA-100VG port adapter can be monitored with the IEEE 802.12 Interface MIB
(DOT12-IF-MIB.my). (For information on accessing Cisco MIB files, refer to the Cisco MIB User

Quick Reference.)

PA-100VG AnyLAN Port Adapter Installation and Configuration 7

What Is the 100VG Port Adapter?

PA-100VG (see Figure 1) is used on the second-generation Versatile Interface Processors (VIP2s)
for use with the Cisco 7500 series routers, and with Cisco 7000 series routers using the RSP7000.
The 100VG port adapter can also be used in Cisco 7200 series routers. There are no chassis or port
adapter slot restrictions for the 100VG port adapter. 100VG port adapters are available as spare parts
(as PA-100VG=).

H6912

• ACTIVITY—This green LED indicates there is activity on the link.

After system initialization, the enabled LED goes on to indicate that the 100VG port adapter has
been enabled for operation. When a port is operational and ready, its link OK LED goes on and
remains on. When a port is active, its activity LED is on when a port on the 100VG port adapter is
receiving a carrier signal from the network and normally off. (The LEDs are shown in Figure 2.)

VIP2 and 100VG Port Adapters

Installing or Replacing a Port Adapter on a VIP2

This section provides the standard procedures for installing or replacing a port adapter on the VIP2.

Depending on the circumstances, you might need to install a new port adapter on a VIP2
motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips
screwdriver, an antistatic mat onto which you can place the removed interface processor, and an
antistatic container into which you can place a failed port adapter for shipment back to the factory.

Caution To prevent system problems, do not remove port adapters from the VIP2 motherboard, or attempt

to install other port adapters on the VIP2 motherboard while the system is operating. To install or replace port
adapters, first remove the VIP2 from its interface processor slot.

Note Each port adapter circuit board is mounted to a metal carrier and is sensitive to ESD damage.

Each port adapter has one Phillips-head screw that secures it to its port adapter slot. We strongly
recommend that the following procedures be performed by a Cisco-certified service provider;
however, this is not a requirement.

While the VIP2 supports online insertion and removal, individual port adapters do not. To replace
port adapters, you must first remove the VIP2 from the chassis, then install or replace port adapters
as required. If a blank port adapter is installed on the VIP2 in which you want to install a new port
adapter, you must first remove the VIP2 from the chassis, then remove the blank port adapter.

Caution To prevent interface reconfiguration requirements, you should replace a port adapter with the same

type of port adapter you removed, but this is not a requirement.

When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to
allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions
requirements, and so that air flows through the chassis properly. If you plan to install a new port
adapter, you must first remove the blank port adapter.

Use the following standard procedure to remove and replace any type of port adapter on a VIP2:

Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Note If you want to install a new port adapter on a VIP2 with a single port adapter, you

must first remove the blank port adapter from the port adapter slot in which you want to
install the new port adapter.

Step 2 For a new port adapter installation or a port adapter replacement, disconnect any interface

cables from the ports on the front of the port adapter, although, this is not required. You
can remove VIP2s with cables attached; however, we do not recommend it.

Step 3 Remove the VIP2 from the system. (Follow the steps in the section “Removing a VIP2”

in the configuration note Second-Generation Versatile Interface Processor (VIP2)
Installation and Configuration [Document Number 78-2658-xx], which shipped with

your VIP2.)

Step 4 Place the removed VIP2 on an antistatic mat.
