What Is the Cisco 1000 Series?
The Cisco 1000 series LAN Extender provides a seamless connection between your remote office local-area network (LAN) and your company's main or regional LAN. The LAN Extender is available in two models:
Because the LAN Extender is remotely configured by your company's system administrator, it can be installed quickly and easily.
The LAN Extender connects to a Cisco router in your company's central office location. This router is called a host router because it is at a central location in your company's LAN. The host router provides routing services to your LAN Extender, and your LAN Extender is configured from the host router.
The host router is connected to your LAN Extender through a 56 or 64-kilobit-per-second (kbps) leased line, or through a faster telephone company service called T1 in North America or E1 in Europe.
Installation is as simple as inspecting the LAN Extender, deciding where to place it, connecting the cables, connecting the power, checking to make sure it all works, and then contacting your system administrator to configure your LAN Extender into the corporate LAN.
How to Install the Cisco 1000 Series LAN Extender
Installing your LAN Extender takes just a few simple steps:
Because any device that uses electricity must be treated with respect, follow these guidelines to ensure general safety:
Keep the LAN Extender in the shipping container to prevent accidental damage until you have determined where you want it installed, then proceed with the unpacking. Check the packing list to ensure that you received the following items:
A warranty sheet, a service and support card, and optional companion publications are included as specified on your order. Inspect all items for shipping damage. If anything appears to be damaged, contact your system administrator.
Following are the tools and parts required to install your LAN Extender:
In addition, you might need the following external equipment:
The Cisco 1000 series LAN Extender can be placed on a desktop or bookshelf, or mounted on a vertical surface. It is designed to allow troublefree operation without requiring cooling fans or special equipment closets or racks.
Setting Your LAN Extender on a Desktop
To place your LAN Extender on a desktop, bookshelf, or other flat, secure surface, perform the following steps:
Mounting Your LAN Extender on the Wall
To install your LAN Extender on a wall or under a desktop, perform the following steps:
After you have installed your LAN Extender, you need to connect the serial cables to your LAN Extender and then connect it to the network. The rear panel of the LAN Extender has the following interface connectors:
You need cables to connect the power and to connect the LAN Extender to the LAN (through either the modular 10BaseT port or the 15-pin AUI port) and WAN lines (through the V.35 or X.21 serial port).
Take the following steps to connect the external cables to the router:
After you have finished installing your LAN Extender, you should make sure everything works properly by checking the LEDs on the front panel.
If you do not see the correct LED signals, or if they blink once or twice per second instead of flicker, refer to the following section, "Troubleshooting," for more information about LEDs and contact your system administrator for additional instructions.
After you have installed the LAN Extender, your system administrator needs to configure it from the host router over a serial line (V.35 or X.21). Contact your system manager with the MAC address from the label included with your LAN Extender. While your LAN Extender is being configured, your system manager may request that you be available to read the LEDs and verify proper operation.
To order UniverCD, Cisco's online library of product information, or paper documentation, refer to the section "Technical Assistance."
This section includes the following troubleshooting information:
The Cisco 1000 series LAN Extender has several LEDs on the front panel that indicate its current operating condition. The LEDs are used by the system administrator to diagnose or verify the operation of the system. You can observe the LEDs, note any fault conditions that the LAN Extender is encountering, and contact your system administrator.
For more complete network troubleshooting information, refer to the Troubleshooting Internetworking Systems publication.
The following are the specifications for the Cisco 1000 series LAN Extender:
If there is a problem with the cables shipped with your LAN Extender, the pinouts can be used for troubleshooting. The following tables list the pinouts for the cables that can be used with the LAN Extender.
