Safety Warnings
See installation instructions before you connect the firewall. This is a summary of safety warnings. For a complete list of warnings for the firewall, including translations, see the SRX5400 Firewall hardware documentation at www.juniper.net/documentation/.
The intrabuilding port(s) of the firewall is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the firewall MUST NOT be metallically connected to interfaces that connect to the outside plant (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.
Before you remove or install components of a firewall, 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 firewall.
An external surge protective device (SPD) should be used at the AC input of the firewall.
Only trained and qualified personnel should install or replace the firewall.
Perform only the procedures described in this guide or the SRX5400 Firewall Hardware Guide. Other services should be performed by authorized service personnel only.
Read the installation instructions before you connect the firewall to a power source.
Before you install the firewall, read the guidelines for site preparation in the SRX5400 Firewall Hardware Guide to make sure that the site meets power, environmental, and clearance requirements for the firewall.
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 devices. Allow 2.8 in. (7 cm) between the side of the chassis and any non-heat-producing surface such as a wall.
When you are installing the firewall, do not use a ramp inclined more than 10 degrees.
Manually installing the firewall requires at least two people to lift the chassis. Before you lift the chassis, remove components as described in the SRX5400 Firewall Hardware Guide. 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.
The firewall should be mounted at the bottom of the rack if it is the only unit in the rack.
When you are mounting the firewall in a partially filled rack, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the firewall in the rack.
When you are removing or installing an electrical component, always place it component-side up on a flat antistatic surface or in an electrostatic bag.
When you are installing the firewall, always make the ground connection first and disconnect it last.
Wire the DC power supply using the appropriate lugs. When you are connecting power, the proper wiring sequence is ground to ground, +RTN to +RTN, and then –48 V to –48 V. When you are disconnecting power, the proper wiring sequence is –48 V to –48 V, +RTN to +RTN, and then ground to ground. Always connect the ground wire first and disconnect it last.
Do not work on the system or connect or disconnect cables during electrical storms.
Before you work on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches. Metal objects heat up when they are connected to power and ground and can cause serious burns or become welded to the terminals.
Failure to observe these safety warnings can result in serious physical injury.
AC power cable warning (Japan):
Warning:The attached power cable is only for this product. Do not use the cable for another product.
