Installing the Chassis

Warning

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. Statement 1021

This equipment must be grounded. 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. Statement 1024

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. Statement 1029

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight of the unit. Statement 1032

Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040

You can set the chassis on a desktop or install it in a rack. See the applicable instructions in the following sections:

•Rack-Mounting the Chassis, page 9

•Installing on Desktop, page 12

Note Cisco 2691 routers are not designed for wall-mounting.

Caution To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always hold the chassis by the metal body.

Rack-Mounting the Chassis

Cisco 2691 routers can be installed in 19- or 23-inch racks with the following chassis orientations:

•Center mounting—Brackets attached in the center of the chassis with either front panel or rear panel facing forward

•Front mounting—Brackets attached at the front of the chassis with the front panel facing forward

•Rear mounting—Brackets attached at the rear of the chassis with the rear panel facing forward
