3. Assemble the clam-shell connector housing around the
terminal block as shown in Figure 2-6. Secure a length of
Tyrap around the housing to reinforce the assembly.
4. Plug the assembled connector into the DC power inlet located
on the upper back panel of the XR900.
5. If there is other equipment requiring DC power, cable those
devices to the DC source as described in the associated
installation guides.
6. For AC equipment such as the system console, plug the
socket end of the unit's power cord into the AC power inlet
on the back of the unit.
7. Plug the power cord of the console terminal (and any other
AC equipment) into an electrical outlet.
8. Turn the DC power back on.
Power Supply Limit Considerations
The XR900 chassis, like the Modular Chassis, can be equipped with
a power supply module accepting either –48Vdc or 115/230Vac
inputs. The +5Vdc output is rated at 5A. The +12Vdc output is rated
at 8A.
The system integrator must ensure that the installed
!
peripheral devices do not exceed the power supply
rating.
Caution
The current rating for the individual outputs must not be exceeded,
and the total power supply output power must not exceed 100
watts.
