"Modular RAID Controller Installation Guide" (on ServerView Suite
DVD 2 under Industry Standard Servers - Expansion Cards - Storage Adapters
- LSI SAS / SCSI RAID Controllers).
Further information on other SAS/SATA RAID controllers (e.g. for
operating external SAS/SATA hard disk drives or tape drives) is available
on ServerView Suite DVD 2 under Industry Standard Servers - Expansion

Accessible drives / components
For all configurations, except those with 16*2.5-inch HDD modules or 8*2.5-
inch HDD modules + LTO drive, a number of mounting locations is available:
– One 3.5-inch slimline bay for an optional Local Service Module:ServerView
Local Service Display (LSD)
– One 3.5-inch slimline bay for an optional optical drive
For a configuration with 3.5-inch HDD modules, an optional DAT or RDX drive
can be installed in the right-hand drive cage. This means that the top two bays
of the drive cage are occupied and are no longer available for HDD modules.
I The accessible drives/components described in this section cannot be
replaced during operation.
USB connectors
Two USB 2.0 connectors on the front of the device support activities carried out
by the service technician. The maximum length of the external cable is two
meters for the USB connectors on the front.
Another four USB 2.0 connectors are available on the rear of the device.
Power supply
In its basic configuration, the server has a hot-pluggable power supply unit that
adjusts automatically to any power voltage in the range from 100 V to 240 V. As
an option, the power supply can be expanded with an extra power supply unit
to create a redundant power supply. If a power supply unit fails, the redundant
configuration assures continued operation. The defective power supply unit can
be replaced during operation (for further details see the "PRIMERGY RX300 S7
Server Upgrade and Maintenance Manual").
