•
Read the installation instructions before you connect the services gateway to a power source.
•
Before you install the services gateway, read the guidelines for site preparation in the SRX5400 Services
Gateway Hardware Guide to make sure that the site meets power, environmental, and clearance
requirements for the services gateway.
•
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 services gateway, do not use a ramp inclined more than 10 degrees.
•
Manually installing the services gateway requires at least two people to lift the chassis. Before you lift
the chassis, remove components as described in the SRX5400 Services Gateway 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 services gateway should be mounted at the bottom of the rack if it is the only unit in the rack.
•
When you are mounting the services gateway 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
services gateway 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 services gateway, 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.
