3.2.14 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 modules can
be used in the basic cabinet and up to four LUNA2 modules can be used in the expansion cab-
inet.
When expanding the HiPath 3800 to a two-cabinet system, two LUNA2 modules in the basic
cabinet and three LUNA2 modules in the expansion cabinet are enough to supply the maximum
configuration in Table 2-7. For information on how to calculate the number of LUNA2 modules
required, see Page 3-62.
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 a battery cabinet.
LUNA2 supports 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 operation
after a power failure, that is, to use uninterruptible power supply functions, you must also con-
nect a battery pack per system cabinet or a BSG 48/38 battery cabinet (including battery charg-
er).
LUNA2 is used in all countries.
Licensed batteries
S30122-K5950-Y200: Battery pack 4 x 12 V/7 Ah
This is the only battery pack approved for operation with LUNA2.
Part numbers
● LUNA2: S30122-K7686-L1, S30122-K7686-M1
For production-related reasons, two different LUNA2 modules with the same functions are
used. Technically identical, the two models have minor mechanical differences and are fully
compatible with each other.
● Battery pack 4 x 12 V/7 Ah: S30122-K5950-Y200
(the connection cable for LUNA2 is part of the battery pack)
● Battery cabinet BSG 48/38: S30122-K5950-F300 (Page 3-63)
– Battery cable for BSG 48/38: S39195-A7985-B10
(A battery cable is required for each system cabinet to be connected.)
– Battery 12 V/38 Ah: S30122-X5950-F320
(Four batteries necessary for each BSG 48/38.)
