protection breaker or an SELV- approved power source in accordance with IEC 60950-1 utilizing 50 A
overcurrent protection.
The input DC cable has an input connector on one end and precut wire on the other end that goes to
the DC power source. The input connector has a locking mechanism that locks onto the DC PSU to
prevent accidental removal of the input DC cable.
If necessary, use appropriate termination lugs for 8 AWG (10 mm
2
) copper-stranded wire on the ends of
the cable to connect to the DC power source.
The blue termination (-48 V) connects to a 50 A overcurrent protection circuit device, and the black
(return) termination connects directly to the RTN bus of the DC power source. The green/yellow
termination (ground) must connect to the same earth ground point as the switch.
Installing a 1200 W DC PSU
To install an Extreme Networks 1200 W DC PSU:
1
Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to the ground
receptacle on the top-left corner of the switch front panel.
CAUTION
Be sure that the grounding point on the back of the switch chassis is securely connected to earth ground. For
information about grounding the switch, see
“Grounding the BlackDiamond 8800 Series Chassis” on page 93
.
2
Verify that the 1200 W DC PSU is right side up, and press the yellow locking lever to the left while
lifting the handle (see
Figure 63
).
NOTE
Do not connect the input DC cable to the DC PSU before you install the DC PSU in the switch.
