Mounting the Chassis
4-4 SmartEdge 1200 Router Hardware Guide
To reduce the risk of fire, electric shock, and personal injury, follow these basic guidelines:
• Carefully examine the installation site for such possible hazards as damp floors, ungrounded power
extension cables, or missing safety grounds before attempting the installation of the system.
• Disconnect all power before installing the system; never assume that power has been completely
disconnected before beginning the installation of the system.
• Do not perform any modifications to the system that can create a potential hazard to people or make the
equipment unsafe.
• Do not work alone when potentially hazardous conditions exist.
• Ensure all fasteners for system and traffic cards and other system components are tightened according
to the guidelines provided in this guide.
Reducing the Risk of ESD Damage
Mounting the Chassis
To mount the SmartEdge 1200 chassis, perform the following sequence of tasks:
1. Select the Chassis Position in the Rack
2. Select the Chassis Alignment
3. Install the Chassis Mounting Brackets
4. Install the Chassis
You must also install or have available an external fuse panel, either a stand-alone unit or incorporated in
a DC power supply system or circuit breaker panel, to be used with the SmartEdge 1200 router. We
recommend that the panel provide separate connectors for all power zones (A1, A2, B1, B2), so that you
can take advantage of the power redundancy provided by the SmartEdge 1200 architecture.
Caution Risk of equipment damage. The system components contain electrostatic-sensitive devices.
ESD damage can occur when electronic components are improperly handled. This damage
can result in complete or intermittent failures of SmartEdge router components.
Follow these simple guidelines at all times to reduce the risk of ESD damage to any of the
SmartEdge router components:
1. Prior to handling any of the system components, always put on an ESD wrist or ankle strap,
ensuring that it makes good contact with the skin.
2. Connect the wrist strap to any proper grounding surface. For convenience, the
SmartEdge 1200 chassis provides two connections for an ESD wrist strap on the front of
the chassis.
3. Avoid touching its printed circuit board, subassemblies, or any connector pins. Always
handle all cards by their ejectors or sides. Place a card on an antistatic surface or in a static
shielding bag when not installed in the chassis.
4. Avoid any contact between a card and your clothing.
