Assembling and Installing DC Power Cables for the Sun SPARC Enterprise T5240 Server 97
3. Locate the three wires coming from your DC power source that will be used in
the connection to your unit:
■
-48V or -60V (negative terminal)
■
Chassis ground
■
-48V or -60V Return (positive terminal)
Note –
Depending on the DC power source, the -48V or -60V (negative terminal)
might be marked with a minus (-) symbol. The -48V or -60V Return (positive
terminal) might be marked with a positive (+) symbol.
4. Strip 1/2 in. (13 mm) of insulation from each of the wires coming from the DC
power source.
Do not strip more than 1/2 in. (13 mm) from each wire. Doing so leaves
uninsulated wire exposed from the DC connector after the assembly is complete.

5. Open the cage clamp by inserting the cage clamp tool (or small screwdriver)
into the rectangular hole directly above the hole in the DC input plug where
you want to insert the first wire, and push in to open the cage clamp.
