cards, blower module, and redundant power modules can be removed and replaced
while the router is operating without presenting an electrical hazard or causing

Before beginning any procedures requiring access to the interior of the router,
•
locate the emergency power-off switch for the room in which you are
working.
Disconnect all external cables before installing or removing a router.
•
Never assume that power has been disconnected from a circuit; always check.
•
Do not perform any action that creates a potential hazard to people or makes
•
the equipment unsafe.
Never install equipment that appears damaged.
•
Carefully examine your work area for possible hazards such as moist floors,
•
ungrounded power extension cables, and missing safety grounds.
If an electrical accident does occur, proceed as follows:
•
Use caution; do not become a victim yourself. Disconnect power to the
–
router.
If possible, send another person to get medical aid; otherwise, assess the
–
condition of the victim and then call for help.
Determine if the person needs rescue breathing or external cardiac
–
compressions, then take appropriate action.
In addition, observe the following guidelines when working with any equipment
that is disconnected from a power source but still connected to telephone or
network wiring:
Never install telephone wiring during a lightning storm.
