To add card slots, you can daisy-chain the APC Silcon Triple Chassis with the standard Triple
Chassis (AP9604) management peripheral, installing the APC Silcon Triple Chassis closer to
the UPS.
4.6.4 Powering the APC Silcon Triple Chassis
The APC Silcon Triple Chassis supplies power to the installed management peripheral cards
and to the Monitoring port, allowing you to power multiple management peripherals.
4.6.4.1AP9604S Power Considerations
The AP9604S model of the APC Silcon Triple Chassis receives its power from the UPS through
the power connector of the Silcon UPS cable. If the total current required by all the installed
management peripherals exceeds 500 mA, you must use a 24 VDC power adapter. To find out
whether you need additional power, see “Determining power requirements”.
4.6.4.2Power Adapters
APC offers two models of 24 VDC power adapter.
• The standard adapter (AP9505) can provide an additional 400 mA.
• The universal adapter (AP9505i) can provide 850 mA.
4.6.4.3Using a Power Adapter
To use the adapter, plug it into a protected power outlet and into the Optional Power port of
the APC Silcon Triple Chassis.
4.6.4.4AP9604SR Power Considerations
The AP9604SR model receives its power from the UPS through the supplied 24 VDC universal
adapter. The total current required by your management peripherals must not exceed the 850
mA limit of the power adapter. See ““Determining power requirements”.
4.6.4.5Determining Power Requirements:
To determine the total amount of current required by your management peripherals, add the
individual current requirements for each management peripheral to be installed with the APC
Silcon Triple Chassis to the current requirements of the chassis itself. Refer to this table
NOTICE!
If the power adapter loses power because of a UPS shutdown, its attached management
peripherals may not operate properly, thus adversely affecting the UPS and its protected
equipment.
