Description
One RIM can be installed in each of the vertical controller bays to the right of
the drives in the main frame DBA (see Figure 3 on page 35). A RIM is required
to provide the Fibre Channel interface to the library's TeraPorter(s). One
additional RIM is required for controller failover, if enabled. To learn more, see
Exporting Controllers on page 53.
Note: Unless otherwise specified, the features of both RIM and RIM2 are the
same and "RIM" is used to refer to both.
The library accommodates multiple generations of high‐performance, high‐
capacity, full‐height and half‐height LTO drives, TS11xx technology drives, or
T10K drives. The drives are installed in DBAs, with each DBA accommodating
up to four drives. Drives are hot‐swappable to provide uninterrupted
operation. To learn more, see Tape Drives on page 55.
Notes:
 Any drive bays that do not have drives installed must have covers installed
to maintain proper air circulation throughout the frame and to protect
internal library components.
 The library does not support placing an LTO drive in Drive Bay Assembly
position 1 if there is a TS11xx technology or T10K drive in Drive Bay
Assembly position 2, or in Drive Bay Assembly position 3 if there is a TS11xx
technology or T10K drive in Drive Bay Assembly position 4.
The PCM supplies power to the power supplies when you press the power
button on the front panel of the main frame. It monitors the power supply
modules in the frame for output voltage, output current, power supply fan
operational status, and power supply operational temperature. The PCM uses
the voltage and current data to calculate the library power usage that is
displayed through the BlueScale user interface.
The 5/12 VDC power supply modules convert AC input to provide the 5 VDC
and 12 VDC power used by the drives in the frame. In the main frame, these
power supplies also provide power to the controller bays, the LCM, the RCM,
and the LCD operator panel. With the exception of its voltage rating, the 5/12
VDC power supply module closely resembles the 24 VDC robotics power
supply module shown on page 37.
There are two different power supplies available depending on the age and
configuration of the library. The number of supplies required by a library is
calculated by Spectra Logic based on the number and type of drives in the
library. Extra supplies provide redundancy and failover protection. The new
and old supplies can be mixed in a power control module and older supplies
can always be replaced by a newer supply. However, newer supplies cannot
always be replaced by an older supply. Contact Spectra Logic Technical
Support (see Contacting Spectra Logic on page 7) for more information.
