Pagina afdrukkenSuperStack 3 Advanced RPS Chassis Loading Limitations
WARNING: Do not overload the chassis — refer to Table 1
"Maximum Number of Advanced RPS Power Modules per Chassis" to
determine loading limitations. It is important that the loading
limitations are not exceeded.
ATTENTION: Ne surchargez pas le châssis — référez-vous au
Tableau 1 "Maximum Number of Advanced RPS Power Modules per
Chassis" pour déterminer les limitations de charge. Il est important
que ces limitations de chargement ne soient pas excédées.
WARNUNG: Bitte überlasten Sie nicht das Chassis —
bezugnehmend auf Tabelle 1 "maximale Anzahl der Advanced RPS
Powermodule per Chassis" und halten Sie die Limitierung ein. Es ist
wichtig, daß Sie die Limitierung nicht überschreiten.
Details of the permitted combinations of modules and 3Com
products are also given in Appendix C of the Advanced RPS Chassis
User Guide (DUA1607-0AAA0x).
Redundant (Single Module) Configuration
The maximum output DC power of the Advanced RPS is 480 W.
However, this can be exceeded only when installing two Type 3
Modules with no other power modules fitted. All other power
module combinations must not exceed 480 W. Refer to Table 1 for
more information on chassis loading limitations.
Fully Redundant (Resilient) Configuration
If you use two Type 3 Modules, connected by a 'Y' cable in full
redundancy mode, these two modules count as one. This is because
a pair of power modules connected with a 'Y' cable draws the same
power as a single power module. In this configuration the modules
power-share, that is, the power drawn by both modules is the same
as that drawn by one module in the single module configuration,
however the ratio the power is drawn by each module can vary, for
example, 50:50, 40:60, and so on.
CAUTION: You must not pair power modules of different types and
power ratings, for example, do not pair a 60 W Type 1 with a 100 W
Type 1, a Type 2 or Type 2A with a Type 3, and so on.
