Cisco 8500 - Energy Hazard; Preventing Electrostatic Discharge Damage; Installation Guidelines

Statement 1255—Laser Compliance Statement
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.
Warning
Energy Hazard
The switches can be configured for a DC power source. Do not touch terminals while they are live. Observe
the following warning to prevent injury.
Preventing Electrostatic Discharge Damage
Many switch components can be damaged by static electricity. Not exercising the proper electrostatic discharge
(ESD) precautions can result in intermittent or complete component failures. To minimize the potential for
ESD damage, always use an ESD-preventive antistatic wrist strap (or ankle strap) and ensure that it makes
adequate skin contact.
Check the resistance value of the ESD-preventive strap periodically. The measurement should be 1–10
megohms.
Note
Before you perform any of the procedures in this guide, attach an ESD-preventive strap to your wrist and
connect the leash to the chassis.
Installation Guidelines
Before installing the chassis, ensure that the following guidelines are met:
• Site is properly prepared so that there is sufficient room for installation and maintenance.
• Operating environment is within the ranges that are listed in Environment and Physical specifications.
For more details on environmental requirements, see Cisco 8100 Router Data Sheet.
• Chassis is mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting the chassis in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
chassis in the rack.
• Airflow around the chassis and through the vents is unrestricted.
• Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent lighting
fixtures. Make sure that the cabling is safely away from other devices that might damage the cables.
