Follow these guidelines to ensure general safety:

Keep the chassis area clear and dust-free during and after installation.

Put the removed chassis cover in a safe place.

Keep tools away from walk areas where you or others could fall over them.

Do not wear loose clothing that could get caught in the chassis. Fasten your tie or scarf and roll up your sleeves.

Wear safety glasses when working under any conditions that might be hazardous to your eyes.

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

Safety with Electricity


Warning    

Read the installation instructions before you connect the system to its power source.



Warning    

Ultimate disposal of this product should be handled according to all national laws and regulations.



Warning   

Only trained and qualified personnel should be allowed to install or replace this equipment.



Warning   

To ensure your safety and the safety of others, be sure the power is OFF and the power cord is unplugged before working on the router.



Warning   

Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals.


Follow these guidelines when working on equipment powered by electricity:

Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF.

Disconnect all power before doing the following:

Installing or removing a chassis

Working near power supplies

Do not work alone if potentially hazardous conditions exist.

Never assume that power is disconnected from a circuit. Always check.

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

If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.

Turn OFF power to the system.

If possible, send another person to get medical aid. Otherwise, determine the condition of the victim and then call for help.

Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. It occurs when electronic printed circuit cards are improperly handled and can result in complete or intermittent failures. Always follow ESD prevention procedures when removing and replacing cards. 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 (Mohm).

Software Requirements

The 6-port modem modules require Cisco IOS Release 11.2(9)P or higher.

Required Tools and Equipment

To install the carrier card and modem modules, you will need the following tools and equipment which are not included:

Cisco AS5300 access server

Feature card removal tool

Medium-size Phillips screwdriver

ESD-preventive wrist strap

ESD-preventive mat

Antistatic bag (optional)

Removing a Carrier Card

This section describes how to remove a carrier card.


Caution   
The carrier cards are not hot-swappable (that is, you cannot remove or install them when the power to the access server is ON). Be sure to turn OFF the power to the access server before installing or removing carrier cards. Failure to do so can damage the access server.

To remove the MICA carrier card:


Step 1 Attach an ESD-preventive wrist strap.

Step 2 Power OFF the access server.

Step 3 On the rear panel of the access server, locate the MICA carrier card (see ).

Figure 1 MICA Carrier Card Faceplate

Step 4 Loosen the two captive screws that secure the carrier card to the chassis until each screw is free of the chassis.

Figure 2 Carrier Card Removal

Step 5 Insert the feature card removal tool so that the slots in each arm of the tool are behind the shoulder of each captive screw, as shown in , and carefully pull the removal tool toward you until the feature card slides free of the chassis.


Caution   
The EMI protective devices on the feature cards are designed to make the cards fit tightly. When removing the cards, they can release suddenly. Exercise caution when removing the feature cards with the removal tool.

Figure 3 Using the Feature Card Removal Tool

Step 6 Set the removed feature card aside on an ESD-preventive mat.

Removing a 6-Port Modem Module

To remove the 6-port modem modules:


Step 1 Make sure that you have attached an ESD-preventive wrist strap and that the system is powered OFF.

Step 2 On the carrier card, locate the 6-port modem module you will replace (see ).

Figure 4 MICA Carrier Card

Step 3 Orient the carrier card so that the modem module socket faces away from you.

Step 4 Gently pry the edges of the 6-port modem module away from the standoffs, as shown in .

Figure 5 Prying the 6-Port Modem Module from the Standoffs

Step 5 Push the two socket latches away from the modem module, as shown in .

Figure 6 Releasing the 6-Port Modem Module from the Socket Latch

Step 6 Remove the modem module from its socket, as shown in .

Figure 7 Removing the 6-Port Modem Module

Installing a 6-Port Modem Module

To install a 6-port modem module:


Step 1 Insert the 6-port modem module into the socket at a 45× angle.

Step 2 Seat the 6-port modem module in the socket and press its edges onto the standoffs, as shown in .

Figure 8 Installing the 6-Port Modem Module

Installing Carrier Cards

To install a carrier card:


Step 1 Remove the carrier card from the ESD-preventive mat.

Step 2 Slide the carrier card into the slot until it touches the backplane connector.

Step 3 Align the captive screws with their holes, and then seat the carrier card completely.

Step 4 Tighten the two captive screws () to secure the carrier card to the chassis.

Figure 9 Carrier Card Installation

Step 5 If the access server is configured with fewer than three cards, make sure that a blank slot cover is installed over each open slot to ensure proper airflow inside the chassis.

5300(config-if)#

Place all asynchronous interfaces in a single group, so that you configure the same parameters quickly on all interfaces at one time.

4

5300(config-if)# ip unnumbered ethernet 0

To conserve IP addresses, configure the asynchronous interfaces as unnumbered and assign the IP address of the Ethernet interface to them.

5

5300(config-if)# encapsulation ppp

Enable PPP1 to run on the set of interfaces in the group.

6

5300(config-if)# async mode interactive

Configure interactive mode on the asynchronous interface.

7
