Safety Warnings

WARNING: See installation instructions before connecting the router. This
is a summary of safety warnings. For a complete list of warnings for this
router, including translations, see the T640 Core Router Hardware Guide at
http://www.juniper.net/techpubs/hardware/
WARNING: The intrabuilding port(s) of the router is suitable for connection
to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s)
of the router 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, Issue
4) and require isolation from the exposed OSP cabling. The addition of primary
protectors is not sufficient protection to connect these interfaces metallically
to OSP wiring.
CAUTION: Before removing or installing components of a router, attach an
ESD strap to an ESD point, and place the other end of the strap around your
bare wrist. Failure to use an ESD strap could result in damage to the router.
CAUTION: Use an external surge protective device (SPD) at the AC input of
the router.
Only trained and qualified personnel should install or replace the router.
Perform only the procedures described in this Quick Start or the T640 Core Router
Hardware Guide. Other services should be performed by authorized service personnel
only.
Incorporate an easily accessible disconnect device into the facility wiring. In the United
States and Canada, the –48 VDC facility should be equipped with a circuit breaker
rated a minimum of 125% of the power provisioned for the input in accordance with
the National Electrical Code in the US and the Canadian Electrical Code in Canada.
WARNING: For six-input DC power supplies, failure to provide the required
circuit breaker or current-limiting fuse for each DC power cable can cause
injury or damage to equipment.
For six-input DC power supplies, each 48 VDC facility DC source input power cable
must be equipped with a current-limiting fuse or circuit breaker external to the Juniper
Networks equipment rated at 100 A (–48 VDC) maximum, or as required by local code.
