|
Note Be sure to leave enough room above and below the Cisco 6920 for airflow. |
To install the chassis in the equipment rack:
Step 1 On the chassis, ensure that all captive screws on the PowerPC card, I/O cards, input cards, and power supply are tightened.
Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.
 |
Tip Two people should perform Step 3 through Step 6. |
Step 3 Position the chassis so that the front end is closest to you; then lift the chassis from both sides and move it to the rack. To prevent injury, avoid sudden twists or moves.
Step 4 Slide the chassis into the rack, pushing it back until the brackets installed at the front of the chassis meet the mounting strips or posts on both sides of the equipment rack.
|
Tip The rack-mount bracket must be placed behind the rack post or mounting strip in the rear installation configuration. |
Step 5 While keeping the brackets flush against the posts or mounting strips, position the Cisco 6920 so that the holes in the brackets are aligned with those in the mounting strips.
Step 6 Insert all four 10/32 x 3/8-inch slotted screws (two on each side) through the brackets and into the mounting strip (use the top and bottom bracket holes. Using a 7/16-inch, flat-blade screwdriver, tighten all the screws.
This completes the procedure for installing the chassis in the rack. Proceed to the "Cabling" section to continue the installation.
This section provides information on connecting your PC or laptop, the LAN, and video cables to your Cisco 6920.
There are three primary ways to access the Cisco 6920. Each has a different purpose.
1. The serial connection uses HyperTerminal and is required when the IP address of the Cisco 6920 is unknown.
2. Connect.exe is an application file included with the Cisco 6920 software bundle. It uses Ethernet and requires an IP address to connect. Connect.exe allows access to the diagnostic menus similar to those seen when using HyperTerminal. Connect.exe is primarily used for software upgrades and environmental parameter changes.
3. Web-based configuration requires an Ethernet connection and uses Netscape Communicator or Microsoft Internet Explorer to connect to the Cisco 6920 using its IP address. The browser connects to the RateMux Manager GUI and is the usual mode for configuring and monitoring the Cisco 6920.
The following sections provide details on how to connect to the Cisco 6920 using each of the three methods.
|
Tip If the IP address is unknown, you can try the default address 10.0.0.200. |
Connect a regular 9-pin serial cable from the serial communications port of the connecting computer to the debug connector on the PowerPC card in the Cisco 6920. This is a straight-through cable, also referred to as an extension serial cable.
|
Note Do not use a null modem cable or you will not be able to connect. |
