Prepare for Installation
Warning
Statement 1055 Class 1/1M Laser
Invisible laser radiation is present. Do not expose to users of telescopic optics. This applies to Class 1/1M
laser products.
Warning 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.
Energy Hazard
The routers can be configured for a DC power source. Do not touch terminals while they are live. Observe
the following warning to prevent injury.
Warning
Statement 1086 Power Terminals
Hazardous voltage or energy may be present on power terminals. Always replace cover when terminals are
not in service. Be sure uninsulated conductors are not accessible when cover is in place.
Preventing Electrostatic Discharge Damage
Many router 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.
Note Check the resistance value of the ESD-preventive strap periodically. The measurement should be 1–10
megohms.
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.
