•
Before installing the services gateway, read the guidelines for site preparation in the
SRX3600 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 installing the services gateway, do not use a ramp inclined more than 10 degrees.
•
Manual installation of the services gateway requires two people to lift the services
gateway chassis. Before lifting the chassis, remove components as described in the
SRX3600 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 handles on the power supplies or on the
Common Form-factor Modules (CFMs). The handles may break off causing the chassis
to fall and inflict injury.
•
The services gateway should be mounted at the bottom of the rack if it is the only unit
in the rack.
•
When 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 removing or installing an electrical component, always place it component-side
up on a flat antistatic surface or in an electrostatic bag.
•
When you install the services gateway, always make the ground connection first, and
disconnect it last.
•
Wire the DC power supply using the appropriate lugs. When connecting power, the
proper wiring sequence is ground to ground, +RTN to +RTN, and then –48 V to –48 V.
When 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 working on equipment that is connected to power lines, remove jewelry, including
rings, necklaces, and watches. Metal objects heat up when 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.
