This chapter describes how to install the Cisco IP/VC 3520 Gateway on the network. The topics include:
This section lists the materials needed to connect and configure the Cisco IP/VC 3520 Gateway.
Your Cisco IP/VC 3520 Gateway package contains:
Inspect the content of the box for shipping damage. Report any damage or missing items to your distributor or reseller.
Before you place the gateway on the network, you must assign it an IP address. The IP address can be set through the serial port on the front of the gateway. This section describes how to use the serial port to configure the gateway with IP address information. You will need the following to set the address:
To set the IP address, perform the following steps:
Step 2 Connect the power cable to the gateway and to a power outlet.
Step 3 Start the terminal emulator on the computer.
Step 4 Set the terminal emulator communication parameters as follows:
Baud Rate | 9600 |
Data Bits | 8 |
Parity | None |
Stop Bits | 1 |
Flow Control | None |
Step 5 Turn on the gateway. A log of gateway events appear on the console.
Step 6 When the message "Press any key to start configuration" appears on the screen, press any key within six seconds. An options list appears.
Step 7 At the prompt, type 1 and press Enter to select the "for configuration of default ethernet port value" option. This option allows you to set the IP address information. The "Enter Default Interface Number" prompt appears.
Step 8 At the prompt, type 1 for port 1. Press Enter. The "Enter IP Address for Interface No. 1" prompt appears.
Step 9 Type the IP address you want to assign to the unit and press Enter. The "Enter Default Router IP address" prompt appears.
Step 10 Type the IP address of the router associated with the segment in which the unit will be installed and press Enter. If you do not want to assign the gateway a router to use at this time, press Enter only. The "Enter IP Mask <HEX>" prompt appears.
Step 11 If the gateway will be associated with a subnet mask, convert the subnet mask IP address to hexadecimal and enter the hexadecimal number at the prompt and press Enter. You can use the desktop calculator to convert the subnet mask ID to hexadecimal. If a subnet mask is not used at this time, press Enter only.
The program writes the information to the gateway firmware.When the activity stops, exit the configuration software and unplug the gateway. Install the gateway on the network in the appropriate segment.
You can install the gateway in a 19-inch rack. The package includes a mounting kit containing two brackets, four washers, and four screws. This section describes how to install the brackets and mount the gateway on a rack.
To attach the mounting brackets, perform the following steps:
Step 2 Position a mounting bracket over the mounting holes on one side of the gateway (see Figure 3-1).
Step 3 Pass the two screws through the washers and bracket holes into the gateway, and tighten them securely with a screwdriver.
Step 4 Repeat Steps 2 and 3 for the other side of the gateway.
Step 5 Insert the gateway into the 19-in. rack and secure. Two screws are needed for each side. These are not provided with the gateway.
Step 6 Verify that the air vents at the sides are not blocked.
The Cisco IP/VC 3520 Gateway has a 10/100BASE-T Ethernet interface that connects to the LAN through an RJ-45 port in the gateway rear panel. To connect the unit to the network, plug one end of an appropriate Ethernet cable into the gateway LAN port and the other into the network.
 |
Note The 10/100BASE-T Ethernet interface the gateway uses supports half-duplex operations only. For optimum performance, make sure that the switch the gateway is connected to automatically sets for half-duplex operation or is manually set for half-duplex operation. |
The Cisco IP/VC 3520 Gateway can have up to four WAN ports. It can have two or four BRI ports, two or four V.35 port, or two BRI ports and two V.35 ports. The following sections describe how to connect the gateway to the WAN interfaces.
To connect a BRI line to the gateway, plug the BRI ISDN line into the first available BRI WAN port in the gateway rear panel for direct connection or plug a cable from a PBX into the first available BRI WAN port for indirect connection. The BRI WAN ports accept RJ-45 connectors.
The gateway BRI modules use the S/T interface. If the ISDN line your phone company provides uses a U interface, you must terminate the line with a Network Terminator 1 (NT1) before connecting line to the BRI connector. Users in the U.S. must set NT1 termination to 100 Ohms. European users must set NT1 termination to 120 Ohms.
Cisco IP/VC 3520 Gateways equipped with V.35 modules support the
V.35 interface with EIA/TIA-366 signalling. A proprietary cable assembly is shipped for each V.35 port the gateway has.
To connect V.35 to the gateway, perform the following steps:
Step 2 Connect the 26-pin connector labeled CBL V.35/RS-366 DTE to the first available V.35 WAN port in the gateway back panel.
Step 3 Connect the cable marked V.35 and that has the Winchester connector to the V.35 port of the PSTN data communications equipment.
Step 4 Connect the cable marked RS-366 and that has the DB-25 connector to the signalling port of the PSTN data communications equipment.
The gateway is equipped with an autoswitching power supply that supports
100 to 240 VAC at 50/60 Hz. A U.S. power cable is shipped with the gateway. If you are installing the gateway outside of the U.S., you may need to obtain a power cable that is compatible with the power outlets of the country where you are installing the unit. We recommend that you use an approved cable that is properly grounded. If you use an outlet adapter, make sure it is properly grounded. Improper grounding can damage the gateway or cause harm.
 |
Warning Do not use a power cable that is not constructed with proper grounding. Nonexistant or improper grounding in the power cable can damage the gateway and dangerously alter the electrical characteristics of the unit. |
To connect the gateway to a power outlet, perform the following steps:
Step 2 Plug the power cord into the power socket on the rear panel of the gateway.
Step 3 Connect the power cable to a grounded AC outlet.
Step 4 Turn the power on. The unit runs the Power On Self Test (POST).
During POST the LEDs on the front panel behave in the following manner:
If the LED indications do not correspond to the normal indications, see "LED Indications" in the "Troubleshooting Tips" chapter.
