|
The gateway module installs in the front of the chassis and provides ISDN or serial functionality. The RTM installs in the rear of the chassis and provides the physical interface for the ISDN or serial line. You must install these modules in corresponding slots in the chassis. That is, if you insert the gateway module in the top slot in the front of the chassis, you must insert the RTM in the top slot in the rear of the chassis.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.
Before opening the chassis, disconnect the telephone network cables to avoid contact with telephone network voltages.
To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.
The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.
Installing the RTM Module
This section describes how to install the RTM module in the Cisco Unified Videoconferencing 3545 chassis. The Rear Transition Module (RTM) provides the ISDN or serial line connections for the gateway.
Warning You must install the RTM module before you install the gateway module. Inserting an RTM module in the rear of the chassis when a gateway module is already installed in the same position at the front of the chassis may damage the chassis.
Procedure
Step 1 On the back of the chassis, loosen the screws of the blank panel covering the slot into which the RTM module is to be installed.
Step 2 Remove the blank panel.
Step 3 Remove the new RTM from the antistatic bag.
Step 4 Press the red buttons and open the handles of the RTM module.
Step 5 Align the edges of the RTM module with the chassis guide rails.
Step 6 Slide the RTM module into the chassis until it stops (see Figure 2-5).
Figure 2-5 Inserting the RTM Module in the Cisco Unified Videoconferencing 3545 Chassis
Step 7 Use even pressure to push the module further into the slot.
Caution Do not force the connection. Forcing the connection can bend or damage the pins in the connector inside the chassis.
Step 8 Snap the handles forward to secure the RTM module in the slot.
Step 9 Secure the RTM module screws.
Caution Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Figure 2-19 DB-25 Pin Layout
Connecting the Gateway to a Power Source
This section describes how to supply power to the gateway. The gateway is equipped with an autoswitching power supply that supports 100-240 VAC at 50/60 Hz.
Warning Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.
Procedure
Step 1 Plug a power cord into the power socket on the rear panel of the gateway.
Step 2 Connect the power cable to a grounded AC outlet.
Step 3 Turn the power on.
Accessing the Gateway Administrator Interface
The Gateway Administrator is a web interface that allows you to view and configure the gateway hardware and application parameters. You can use the gateway interface to:
•Set administrative parameters to define access to the gateway
•Set gateway application parameters that specify how the gateway processes incoming and outgoing calls
•Set chassis operating parameters for Cisco Unified Videoconferencing 3545 Gateway modules installed in the top slot of a Cisco Unified Videoconferencing 3545 chassis
Before You Begin
The following requirements are necessary to access the gateway Administrator web interface:
•A Java-compliant browser. Microsoft Internet Explorer version 5.5 or later is recommended.
•The gateway IP address or a web link to the gateway.
•Administrator level-access
•The required user name and password.
Note For first-time installation, you must assign an IP address to the gateway using a serial port connection before you can access the web interface. For more information, see the "Setting the IP Address" section.
Procedure
Step 1 Launch your browser and type the IP address or the name of the gateway.
For example, http://125.221.23.44 or board_name.
Step 2 Type the Administrator user name and password in the appropriate fields and click Login. The default global user name is admin. The default password is <null>.
Note If you try to sign in as an Administrator and another Administrator is currently signed in, the gateway signs you in as a Read only user and the words Read Only appear at the top of the window. Read only users cannot edit any of the gateway settings.
Registering the Online Help
The online help files for the Cisco Unified Videoconferencing 3545 Gateway Administrator interface are shipped on the Cisco Unified Videoconferencing Software CD-ROM. To use the online help, you must install the help files for the appropriate Cisco Unified Videoconferencing 3545 Gateway in a shared directory on your network and register the directory location in the Administrator interface.
If you wish to install the online help on a shared network location and link it to the Cisco Unified Videoconferencing 3545 Gateway Administrator, see the document Installing Online Help for Cisco Unified Videoconferencing 3500 Products.
Netscape Navigator Users
Online help files located on the local network and accessed using Netscape Navigator 4.x must be located on a mapped network drive.
