5–6 DEChub 900 MultiSwitch Owner’s Manual
You can determine if the hub has enough power for a new module by:
• Reading the power requirements label on the module or module
documentation.
• Reading the Hub Status Display to determine that the required
power is available.
• Comparing the module’s 5-volt, 15-volt, and Total Power (Watts) values with
the Hub Status Display Available power values and ensuring all three
power values are met.
Power supply modules may be added to provide power as needed for any
configuration.
When you install half-height modules in a hub, the Hub Manager automatically
deducts 7.5 watts of power from the available power. Once the module’s self-test is
complete, the Hub Manager recognizes the module’s identity. This includes its actual
power consumption, and may recalculate the available power, thus reflecting the
module’s actual power needs.
When a module is removed from an operational hub, the Hub Manager will display an
event notification on the Hub Status Display, and the available power will be updated
(increased) by the amount of power that was consumed by the module that was
removed.
Any module that does not pass self-test procedures should be removed from the
hub.
