IMPORTANT SAFETY INSTRUCTIONS
Pluggable optical modules comply with IEC 60825-1 Ed. 3 and 21 CFR 1040.10 and 1040.11 with or without
exception for conformance with IEC 60825-1 Ed. 3 as described in Laser Notice No. 56, dated May 8, 2019.
Note
Read the installation instructions before using, installing or connecting the system to the power source.
Warning
Proceed with the installation if you have already unpacked your chassis and read all the site requirements for
your new equipment.
Note
Guidelines for Installation
The chassis should already be in the area where you want to install it. If you have not determined where to
install your chassis, see
Preparing Your Site for Installation
for information about site considerations.
• The Cisco Catalyst 8500 Series Edge Platforms require at least 3 inches (7.62 cm) of clearance at the
inlet and exhaust vents (the front and rear sides of the chassis) for installing on a tabletop. The Cisco
Catalyst 8500 Series Edge Platforms requires a minimum of 1.75 inches or 4.45 cm rack units of vertical
rack space. Measure the proposed rack location before mounting the chassis in the rack.
• The chassis should be installed off the floor. Dust that accumulates on the floor is drawn into the interior
of the router by the cooling fans. Excessive dust inside the router can cause overtemperature conditions
and component failures.
• There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the chassis to
install and replace FRUs, or to access network cables and equipment.
• Maintain a minimum clearance of 3 inches on the front and back sides of the chassis for the cooling air
inlet and exhaust ports, respectively. Avoid placing the chassis in an overly congested rack or directly
next to another equipment rack; the heated exhaust air from other equipment can enter the inlet air vents
and cause an overtemperature condition inside the router.
• The chassis needs adequate ventilation. Do not install it in an enclosed cabinet where ventilation is
inadequate.
• Keep the cable-management bracket ready if you plan to install it on the front of the chassis.
• Ensure that an adequate chassis ground (earth) connection exists for your router chassis (see the "
" section).
