Apply DC power to the switch (for DC models)
Read the Safety and Statutory Information booklet before connecting a DC
power supply. A copy of this booklet is included with each switch. It is also
included on the Documentation and Tools CD-ROM, or can be
downloaded from
www.alliedtelesis.com/support/documentation/
Only trained and qualified personnel should connect a DC power supply. Due
to exposed terminals, DC powered switches should be installed only in
Restricted Access Areas.
DC supply cable specifications:
•
Number of wires (cores): 3
•
Minimum size: 2.1mm
•
Minimum cable rating: 600V, 90 degrees Celsius
DC power supply specifications:
•
48 VDC (39-60 VDC is acceptable)
•
Either positive grounded or negative grounded
Circuit protection:
•
Use a 10 Amp circuit breaker
To connect the DC supply:
a) Ensure the supply cable is not live
b) Strip the supply cable wires to expose 8mm (0.31 in.) of bare conductor
c)
At the switch, connect the ground wire to the ground terminal
(terminals can be identified by the diagram on the switch's rear panel,
see Figure 2). Tighten the terminal to between 0.6-0.8 Nm (0.041-0.055
pound-force per foot)
d) At the switch, connect the positive feed to the + (positive) terminal and
the negative feed to the - (negative) terminal. Tighten the terminals to
between 0.6-0.8 Nm (0.041-0.055 pound-force per foot)
e) Ensure there are no exposed conductor strands
f)
Secure the supply cable (to the rack framework or similar object) so that
the connections are isolated from any force applied to the cable
g) Ensure the circuit breaker is in the Off position
h) Connect the supply-cable wires to the circuit breaker
i)
Energise the circuit breaker
