This chapter describes how to install the Access Gateway module in a Catalyst 4000 family switch chassis.
This chapter contains these sections:
 |
Caution You cannot hot swap VIC, VWIC, or WICS. Their installation requires removal of the Access Gateway module from the chassis. |
 |
Warning Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system. |
Before you install the Access Gateway module, you need these tools:
|
Caution Whenever you handle switching modules, you should use a wrist strap or other grounding device to prevent ESD damage. |
You also need an appropriate connecting cable to install and connect your module. The cable type required for each module is described in the section for that module.
These items are optional:
|
Caution To prevent ESD damage, handle switching modules by the carrier edges only. |
To remove a switching module from a Catalyst 4000 family switch, perform these steps:
Step 2 Loosen the captive installation screws, as shown in Figure 3-1.
Step 3 Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the switching module from the backplane connector.
Figure 3-1 shows a close-up of the right ejector lever.
Step 4 Grasp the switching module front panel with one hand and place your other hand under the carrier to support and guide it out of the slot.
Do not touch the printed circuit boards or connector pins.
Step 5 Carefully pull the switching module straight out of the slot, keeping your other hand under the carrier to guide it.
Step 6 Place the switching module on an antistatic mat or antistatic foam, or immediately install it in another slot.
Step 7 If the slot is to remain empty, install a switching module filler plate (part number 800-00292-01).
All Catalyst 4000 family switching modules are installed in horizontal chassis slots that are numbered from top to bottom.
|
Caution To prevent ESD damage, handle the Access Gateway modules by the carrier edges only. |
To install the Access Gateway module in a Catalyst 4000 family switch, perform these steps:
Step 2 Choose a slot for the new Access Gateway module.
Be sure that you have enough clearance to accommodate any interface equipment that you will connect directly to the Access Gateway module ports. If possible, place Access Gateway modules between empty slots that contain only switching module filler plates.
Step 3 Loosen the captive installation screws securing the switching module filler plate (or the existing switching module) to the desired slot.
Step 4 Remove the switching module filler plate (or the existing switching module). Save the switching module filler plate for future use.
 |
Note If you are removing an existing switching module, refer to the "Removing Catalyst 4000 Switching Modules" section. |
Step 5 To install the new Access Gateway module, hold the switching module front panel with one hand, and place your other hand under the carrier to support the module, as shown in Figure 3-2. Do not touch the printed circuit boards or connector pins.
Step 6 Align the edges of the Access Gateway module carrier with the slot guides on the sides of the switch chassis, as shown in Figure 3-2.
Step 7 Pivot the two module ejector levers out away from the faceplate.
Step 8 Carefully slide the Access Gateway module into the slot until the notches on both ejector levers engage the chassis sides.
Step 9 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers to fully seat the Access Gateway module in the backplane connector.
|
Caution Always use the ejector levers when installing or removing Access Gateway modules. A module that is partially seated in the backplane will cause the system to halt and reset. Make sure the ejectors are locked when the module is in the slot. |
Step 10 Use a screwdriver to tighten the captive installation screws on each end of the Access Gateway module faceplate.
The Access Gateway module can take up to two minutes to boot and it does not appear on the supervisor engine console until IOS is operating.
To check the status of the module, perform these steps:
Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the new module and that the status of the module is good.
Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer service representative.
The Access Gateway module has three slots for voice interface cards (VICs), WAN interface cards (WICs), and VIC/WIC interface cards (VWICs). You can install any combination of VICs, WICs, and VWICs in slots 1 and 2, but slot 3 only supports VICs and VWICs.
VICs, WICs, and VWICs do not support online insertion and removal (hot swapping).
|
Caution Before inserting a VIC/WIC into the Access Gateway module, you must turn off the electrical power by either powering off the switch or unplugging the Access Gateway module from the chassis and disconnecting the network cables. |
To install a VIC/WIC, perform these steps:
Step 2 Use either a number 2 Phillips screwdriver or a small flat-blade screwdriver to remove the blank filler panel from the VIC/WIC slot where you plan to install the module. Save the filler panel for future use.
Step 3 Align the module with the guides in the VIC/WIC slot and slide it gently into the slot. (See Figure 3-3.)
Step 4 Push the module into place until you feel its edge connector mate securely with the connector in the VIC/WIC slot.
Step 5 Fasten the VIC/WIC's captive mounting screws into the holes in the Access Gateway module faceplate using the Phillips or flat-blade screwdriver.
Step 6 Reinsert the Access Gateway module, restore the power, reinstall the network interface cables, and turn on power to the switch.
These sections decribe how to connect the following VWICs, WICs, and VICSs.
This section describes how to connect and check the status on the 1-port multiflex trunk interface cards:
For this connection, use the straight-through RJ-48C-to-RJ-48C cable that shipped with your Access Gateway module. To connect this interface card, follow these steps:
Step 2 Connect one end of the cable to the T1 or E1 port on the card.
Step 3 Connect the other end of the cable to the T1 or E1 wall jack (RJ-48C) at your site, as shown in Figure 3-4.
Step 4 Turn on power to the switch.
Step 5 Check that the CD LED goes on, which means that the internal DSU/CSU is communicating with the DSU/CSU at the T1 or E1 service provider's central office.
Table 3-1 describes the interface card LEDs.
| LED | Description | Color |
|---|---|---|
LP | On means that a loopback or line state is detected or is manually set by the user. This LED is off during normal operation. | Yellow |
AL | On means that there is a local or remote alarm state. This LED is off during normal operation. | Yellow |
CD | On means that a carrier has been detected and the internal DSU/CSU in the VWIC is communicating with another DSU/CSU. This LED is on during normal operation. | Green |
This section describes how to connect and check the status on the 2-port multiflex trunk interface cards.
For this connection, use the straight-through RJ-48C-to-RJ-48C cable that came with your Access Gateway module. To connect this interface card, follow these steps:
Step 2 Connect one end of the cable to the T1 or E1 port on the card.
Step 3 Connect the other end of the cable to the T1 or E1 wall jack (RJ-48C) at your site, as shown in Figure 3-5.
Step 4 Turn on power to the switch.

This section describes how to connect and check the status on the 1-port 56/64-kbps WIC.
You must provide a straight-through RJ-48S-to-RJ-48S or a straight-through
RJ-48C-to-RJ-48C cable for this connection. To connect this interface card, follow these steps:
Step 2 Connect one end of the cable to the 56/64-kbps port.
Step 3 Connect the other end to the RJ-48S wall jack, as shown in Figure 3-7.
Table 3-4 describes the interface card LEDs.
| LED | Description |
|---|---|
TD | Data is being transmitted to the DTE interface. |
RD | Data is being received from the DTE interface. |
LP | Internal DSU/CSU is in loopback mode. |
AL | One of these alarm conditions is present: no receive signal, loss of frame signal from the remote station, or out of service signal from the remote station. This LED is off during normal operation. |
CD | Internal DSU/CSU in the WIC is communicating with another DSU/CSU. |
This section describes how to connect and check the status on the 2-port asynchronous/synchronous serial card.
|
Note The Catalyst 4000 Access Gateway module does not support asynchronous mode at this time. |
The 2-port A/S serial card has "smart serial" ports. The serial cable attached to this port determines the electrical interface type and mode (DTE or DCE).
Six types of serial cables (also called serial adapter cables or serial transition cables) are available from Cisco Systems:
All serial cables provide a universal plug at the interface card end. The network end of each cable provides the physical connectors that are most commonly used for the interface. For example, the network end of the EIA/TIA-232 serial cable is a DB-25 connector, which is the most widely used EIA/TIA-232 connector.
All serial interface types except EIA-530 are available in DTE or DCE format: DTE with a plug connector at the network end and DCE with a receptacle at the network end. V.35 is available in either mode with either gender at the network end. EIA-530 is available in DTE only.
After you install the A/S serial card, use the appropriate serial cable to connect the serial port on the card to one of the following types of equipment (see Figure 3-8):
To connect this interface card, follow these steps:
Step 2 Connect one end of the appropriate serial cable to the DB-60 port.
Step 3 Connect the other end of the cable to the appropriate type of equipment, as shown in Figure 3-8.
Step 4 Turn on power to the switch by pressing the power switch to the on ( | ) position.
Step 5 Check that the CONN LED goes on, which indicates that the serial port on the card detects the WAN serial connection.
If you have additional cards to install, proceed to the appropriate section in this document. When you have finished all installations, refer to the Software Configuration Guide for your switch.
This section describes how to connect and check the status on the 2-port FXS voice interface card.
The FXS voice interface card includes two jumper headers (W3 and W4) to set loop-start or ground-start mode. One jumper configures each FXS port. The default setting, which should be satisfactory in most installations, is loop start. In this setting, jumpers are placed over positions 2 and 3 of headers W3 and W4.
Most modern central office equipment, such as DMS-100 and 5ESS switches, provides calling party control (CPC) and Ring on Seize on loop-start lines. CPC provides faster disconnection, and Ring on Seize minimizes glare (collision of inbound and outbound calls on the same interface). If your central office does not provide these features on loop start, you may want to configure the FXS card for ground-start operation instead by moving the jumpers to positions 1 and 2.
For proper operation, both jumpers must be configured identically. In most cases, the jumper setting should have little or no effect on operation.
|
Note This jumper setting does not apply to VIC-2FXS-EU. |
Use a standard RJ-11 modular telephone cable to connect the 2-port FXS voice interface card to the PSTN or PBX through a telephone wall outlet. To connect this interface card, follow these steps:
Step 2 Connect one end of the cable to an RJ-11 port on the card. (See Figure 3-9.)
Step 3 Connect the other end of the cable to the telephone wall outlet (RJ-11 port).
|
Caution Connect only an FXS interface approved for use in your country to the PSTN. Otherwise, connect the FXS interface only to a PBX. Connections from the PBX to the PSTN are permitted. |
This section describes how to connect and check the status on the 2-port FXO voice interface card.
The FXO voice interface card includes two jumper headers (W3 and W4) to set loop-start or ground-start mode. One jumper configures each FXO port. The default setting, which should be satisfactory in most installations, is loop start. In this setting, jumpers are placed over positions 2 and 3 of headers W3 and W4.
Most modern central office equipment, such as DMS-100 and 5ESS switches, provides calling party control (CPC) and Ring on Seize on loop-start lines. CPC provides faster disconnection, and Ring on Seize minimizes glare (collision of inbound and outbound calls on the same interface). If your central office does not provide these features on loop start, you may want to configure the FXO card for ground-start operation instead by moving the jumpers to positions 1 and 2.
For proper operation, both jumpers must be configured identically. In most cases, the jumper setting should have little or no effect on operation.
|
Note This jumper setting does not apply to VIC-2FXO-EU. |
Use a standard RJ-11 modular telephone cable to connect the 2-port FXO voice interface card to the PSTN or PBX through a telephone wall outlet. To connect this interface card, follow these steps:
Step 2 Connect one end of the cable to an RJ-11 port on the card. (See Figure 3-10.)
Step 3 Connect the other end of the cable to the telephone wall outlet (RJ-11 port).
The VIC-2FXO-EU is intended for use in Europe. In countries where PSTNs do not use RJ-11 wall outlets, use a suitable adapter to convert the plug on an RJ-11 modular cable to the type of wall outlet connector used locally. These adapters are not sold by Cisco Systems, but are available from other vendors.
|
Caution Connect only an FXO interface approved for use in your country to the PSTN. Otherwise, connect the FXO interface only to a PBX. Connections from the PBX to the PSTN are permitted. |
The console and 10/100 Mbps Ethernet management ports are located on the front panel of the Access Gateway module. (See Figure 3-1) The console and Ethernet management ports use an RJ-45 media-dependent interface crossed-over (MDIX) connector (see Figure 3-11). Table 3-5 lists the console port pinouts and Table 3-6 lists the 10/100 Mbps Ethernet management port pinouts.
|
Note The MDIX ports are crossed over internally. For an MDI-to-MDI or MDIX-to-MDIX connection, use a crossover cable. For an MDI-to-MDIX connection, use a straight-through cable, which allows the Tx pins to connect with the Rx pins. |
