Library Access Provide a Category 5 (10/100BaseT connection) data-grade
Ethernet cable that is compliant with EIA/TIA 568 from an active Ethernet
network. This cable must be connected to an Ethernet port on the LCM for
remote access to the library’s BlueScale web interface and to allow for the
library to automatically email notifications to users and AutoSupport
tickets to Spectra Logic Technical Support. During installation, the library’s
connection is set up with the library’s IP address, subnet, proxy server, and
other IP configuration settings.
Host Access Provide one or two optical fiber cables from the arbitrated
loop or switched fabric, to Fibre Channel port(s) on a RIM in each partition
to provide the hosts with access to the medium changer. Depending on the
wavelength, the cables must comply with the following specifications in
the Fibre Channel standard (FC-PI-2):
 50-micron—400-M5-SN-I classification
 62.5 micron—400-M6-SN-I classification (not supported for RIM2)
Tape Drive Access
 Fibre Channel—Provide one optical fiber cable from the arbitrated loop
or switched fabric, to a Fibre Channel port on each drive, to provide the
hosts with access to the drives. Depending on the wavelength, the
cables must comply with the following specifications in the Fibre
Channel standard (FC-PI-2):
 50-micron—400-M5-SN-I classification
 62.5 micron—400-M6-SN-I classification (not supported for LTO-6
or later generation drives or TS11xx technology drives)
The following table can be used to determine the maximum length for
an M5 cable.
 Serial Attached SCSI (SAS)—SAS tape drives support the point-to-
point Serial Attached SCSI protocol. Connecting these drives to the host
network requires a SFF-8088 SAS cable rated for 6 Gb/second that does
not exceed 13 feet (4 m).
Caution
Some port scanning software can interfere with remote library sessions.
