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 ACX5448
Universal Metro Router Hardware Guide at
https://www.juniper.net/documentation/
.
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 must install or replace the router.
•
Perform only the procedures described in this quick start or the ACX5448 Universal Metro Router Hardware Guide at
https://www.juniper.net/documentation/
. Other services should be performed by authorized service personnel only.
•
Read the installation instructions before you connect the router to a power source.
•
Before installing the router, read the guidelines for site preparation in the ACX5448 Universal Metro Router Hardware
Guide at
https://www.juniper.net/documentation/
to make sure that the site meets power, environmental, and clearance
requirements for the router.
•
For the cooling system to function properly, the airflow around the chassis must be unrestricted. Allow at least 6 in.
(15.2 cm) of clearance between side-cooled routers. Allow 2.8 in. (7 cm) between the side of the chassis and any
non-heat-producing surface such as a wall.
•
When installing the router, do not use a ramp inclined more than 10 degrees.
•
Manually installing the router requires two people for an empty chassis and three people for a fully configured router
to lift the chassis. Before lifting the chassis with only two people, remove the components as described in the ACX5448
Universal Metro Router Hardware Guide at
https://www.juniper.net/documentation/
. To prevent injury, keep your back
straight and lift with your legs, not your back. Do not attempt to lift the chassis by the power supply handles.
