Figure 3.10. A NetWall 6000 Series PSU (DC Power)
A NetWall 6000 Series PSU has a single DC input supp/- 48VDC and return feed. A
dedicated circuit breaker supporting the labeled current requirements is needed for each PSU if
two are installed.
It is common that DC power is routed through DC power distribution panels on each rack in a
typical site, and using battery backups providing 48 VDC. These might be located at the top of
each rack in which the NetWall 6000 Series is to be installed. Two pairs of suitable cables
connected to each set of terminal studs on the power distribution panel are required.
Make sure to connect the input and return feed to the correct power distribution feed since
there is no standard coloring scheme for DC power cables. The 6000 Series appliance
must
be
connected to earth ground during operation. Connect a cable to an earth ground from the
cabinet or other suitable grounding point to the chassis by fastening a U-type lug to the end of
the ground wire and fasten it to the chassis with the power supply retaining screw.
Important
The power feed ground and chassis ground must be connected to the same earth point
at an installation site.
The following procedure is required for connecting power to a PSU:
1.
Connect the 6000 Series appliance to an earth ground with the following steps:
i.
Ensure a suitably qualified electrician has correctly installed the wiring.
ii.
Connect one end of a suitable cable to the chassis ground point.
iii.
Connect the other end of the cable to an earth ground. For example, to the rack
cabinet in which the 6000 Series appliance is installed.
2.
Connect suitable DC cables to the first PSU with the following steps:
i.
Make sure that the voltage from all DC power source cables is 0V before and during
installation. Take precautions so that power cannot accidentally be restored during
installation.
ii.
Ensure a suitably qualified electrician has correctly installed all power connections.
iii.
Connect the 6000 Series DC power connector cable U-type lugs to the power
distribution panel:
•
Fasten the positive (yellow) cable lug to the "+" distribution panel.
