HiPath 3000 System Overview
HiPath 3800
2.2.4.2 LUNA2
Introduction
LUNA2 (Line-powered Unit for Network-based Architecture No. 2) is used as the central power
supply in HiPath 3800. Depending on the system configuration, up to three LUNA2 boards can
be used in the basic cabinet and up to four in the expansion cabinet.
When configuring the HiPath 3800 as a two-cabinet system, two LUNA2 boards in the basic
cabinet and three in the expansion cabinet are sufficient to provide the specified maximum con-
figuration limits. For information on how to calculate the number of LUNA2 modules required,
see Page 2-18.
You can use a third LUNA2 in the basic cabinet and a fourth in the expansion cabinet to
● ensure error-free operation if one LUNA2 module fails (redundant LUNA2).
● load a connected battery pack or battery cabinet.
LUNA2 combines power supply and battery management functions. No other components are
required if it is operated as a power supply. To maintain short-term battery emergency opera-
tion after a power failure, that is, to use uninterruptible power supply functions, you must also
connect a battery pack for each system cabinet or a BSG 48/38 battery cabinet (including bat-
tery charger).
LUNA2 is used in models for all countries.
