4.7.2.4 Optional Power Input
With the Optional Power input, you can power the APC Silcon Triple Chassis from an external source, using a 24 VDC power adapter. A universal adapter (AP9505i) or a standard adapter (AP9505) can be purchased separately from APC.
4.7.3 Installing Management Peripherals
There are two basic types of APC management peripherals that work with the APC Silcon Triple Chassis:
•Management peripheral cards, which fit into external management peripherals that are equipped with a card slot.
•External management peripherals, which connect to the Monitoring (or Advanced) port of other external management peripherals.
NOTICE!
The name “Monitoring” port varies from product to product, but its purpose is the same – to replicate the UPS communications port.
