Preventing Electrostatic Discharge Damage
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
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.

Check the resistance value of the ESD-preventive strap periodically. The measurement should be 1–10
megohms.
The intrabuilding port(s) of the equipment or subassembly, which is the management Ethernet port, must use
shielded intrabuilding cabling/wiring that is grounded at both ends. Statement 7003
The intrabuilding port(s) of the equipment or subassembly, which is the management Ethernet port, must not
be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed
for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and require
isolation from the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in
order to connect these interfaces metallically to OSP wiring. Statement 7005
This equipment shall be connected to AC mains provided with a surge protective device (SPD) at the service
equipment complying with NFPA 70, the National Electrical Code (NEC). Statement 7012
This equipment is suitable for installations utilizing the Common Bonding Network (CBN). Statement 7013
The battery return conductor of this equipment shall be treated as (DC-I). Statement 7016
This equipment is suitable for installation in Network Telecommunications Facilities. Statement 8015
