| 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:
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). |
The 6-port modem modules require Cisco IOS Release 11.2(9)P or higher.
To install the carrier card and modem modules, you will need the following tools and equipment which are not included:
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 2 Power OFF the access server.
Step 3 On the rear panel of the access server, locate the MICA carrier card (see Figure 1).
Step 4 Loosen the two captive screws that secure the carrier card to the chassis until each screw is free of the chassis.
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 Figure 3, 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. |
Step 6 Set the removed feature card aside on an ESD-preventive mat.
To remove the 6-port modem modules:
Step 2 On the carrier card, locate the 6-port modem module you will replace (see Figure 4).
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.
Step 5 Push the two socket latches away from the modem module, as shown in Figure 6.
Step 6 Remove the modem module from its socket, as shown in Figure 7.
To install a 6-port modem module:
Step 2 Seat the 6-port modem module in the socket and press its edges onto the standoffs, as shown in Figure 8.
To install a carrier card:
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 (Figure 9) to secure the carrier card to the chassis.
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.
This section describes how to configure the 6-port modem modules. Take the steps described in the following tables to configure the access server:
For a description of AT commands and registers for the 6-port modem modules, see the AT Command Set and Register Summary for MICA Six-Port Modules publication (document number 78-4533-xx), which ships with the Cisco AS5300 access server.
| Step | Command | Purpose |
|---|---|---|
| 1 | Password: <password> | Enter enable mode. Enter the password. You have entered enable mode when the prompt changes to |
| 2 | | Enter global configuration mode. You have entered global configuration mode when the prompt changes to |
| 3 | 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 | | To conserve IP addresses, configure the asynchronous interfaces as unnumbered and assign the IP address of the Ethernet interface to them. |
| 5 | | Enable PPP1 to run on the set of interfaces in the group. |
| 6 | | Configure interactive mode on the asynchronous interface. |
| 7 | | |
| 8 | | Support dial-in PC clients. At the global level, define the pool of sddresses |
| 9 | Building configuration... | Define the group range of the interface. The number you use with the group-range command depends on the number of asynchronous interfaces you have on your access server. That is, if your access server has 48 asynchronous interfaces, you can specify group-range 1 48. If 60, specify group-range 1 60. |
| 1PPP = Point-to-Point Protocol. 2CHAP = Challenge Handshake Authentication Protocol. 3PAP = Password Authentication Protocol. |
| Step | Command | Purpose |
|---|---|---|
| 1 | | Enter the number of modem lines to configure. If you have 48 modems, enter line 1 48. If 60, enter line 1 60. Note: There are 12 modems on each 56K module. |
| 2 | | Configure the access server modems to use a default configuration string (chat script). A string of modem configuration commands is sent to the modem each time it is reset. |
| 3 | | Allow all protocols to be used when connecting to the line. |
| 4 | | Enable remote IP users running a PPP application to dial in, bypass the EXEC facility, and connect directly to the network. |
| 5 | | Enable both incoming and outgoing calls. |
| 6 | | Enable hardware flow control. |
| 7 | | Exit to global configuration mode. |
| Step | Command | Purpose |
|---|---|---|
| 1 | 5300(config)# isdn switch-type primary-5ess | Enter your telco's switch type. The following switch types are available: primary-4ess, primary-5ess, primary-dms100, primary-net5, primary-ntt, and primary-ts014. |
| 2 | | Enter controller configuration mode to configure your controller port. The controller ports are labeled 0 through 3 on the quad T1/PRI and quad E1/PRI cards. |
| 3 | | Enter your telco's framing type. The following framing types are available: esf, sf, crc4, and nocrc4. |
| 4 | | Enter your telco's line code type. The following line code types are available: ami, b8zs, and hdb3. |
| 5 | | Enter the clock source for the line. Configure one line as the primary or most stable clock source line. Configure the other line as the secondary clock source line. |
| 6 | | Configure all channels for ISDN. Enter pri-group timeslots 1-24 for T1. If E1, enter pri-group timeslots 1-31. |
| 7 | | Repeats steps 2 to 6 to configure the second controller. Note that the controller number is 1, instead of 0. And the clock source is secondary, instead of primary.
|
| Step | Command | Purpose |
|---|---|---|
| 1 | 5300(config-if)# | Enter serial interface configuration mode. After you have configured the controller, a corresponding D-channel serial interface is created instantly. Serial interface 0:23 is the D-channel for controller 0. You must configure each serial interface to receive incoming and send outgoing modem signaling. |
| 2 | | Assign an IP address and subnet mask to the interface. |
| 3 | | Configure all incoming voice calls to go to the modems. |
| 4 | %SYS-5-CONFIG_I: Configured from console by console <Return> | Return to privileged EXEC mode. When this message appears, press Return to get the |
| 5 | 5300# copy running-config startup-config | Save the configuration changes to NVRAM. |
To verify that the new modems are working properly, enter the following command:
5300# debug modem
You should receive a set of messages similar to the following:
