SpycerBox Ultra Hardware Guide
To provide connections to most networks there are various interface
possibilities optionally available for the SpycerBox Ultra, such as the fol-
lowing:
The DVS system provides furthermore the following connection possi-
bilities by default:
2.2.5 Power Supply
The redundant power supply provides the system with power. It con-
sists of several independent power supply units: Even if one fails the
others will still offer enough power to keep the system working.
The following provides an overview of one of the power supply units:
Gigabit Ethernet Either a 1 Gigabit Ethernet connection with four
ports or a 10 Gigabit Ethernet connection with
up to two ports.
InfiniBand InfiniBand connection with up to two ports.
Fibre Channel Two port Fibre Channel interface.
FireWire Two port FireWire interface.
graphic card The monitor for the DVS system has to be con-
nected here. For further information about the
graphic card, please refer to the original manu-
facturer’s documentation included in the deliv-
ery of the system.
SAS The SAS (serial attached SCSI) connector is an
external mini-SAS (SFF-8088) connector that
can be used to connect external storages. An
external storage connected to this port can even
be configured to provide RAID protection.
Data transfers on this port may inter-
fere with the real-time capability of the
DVS system. It is recommended to use
it only at times when no real-time per-
formance is required.
The system can be operated with one power supply unit out
of order. However, if another one fails, a continued operation
of the system cannot be guaranteed. Therefore, it is recom-
mended to change a failed power supply unit immediately
(see section “Power Supply Maintenance” on page 5-13).
The state of the power supply units can be easily checked ei-
ther with their LEDs as explained below or with the general
alarm LED (see section “Operation Items” on page 2-7).
