38 Library Installation and CRU Replacement
9 Install the module terminators.
a. Using the module terminators, terminate the top and bottom modules in the library stack. Install
one module terminator in the top terminator connector on the topmost module and one in the
bottom terminator connector on the bottommost module.
If your library configuration consists of a single module, place module terminators in the
module’s top and bottom module terminator connectors.
b. If you need to add 9U expansion modules to the 5U library control module, remove the module
terminator from the 5U library control module terminator connection that is closest to the 9U
expansion module.
c. Replace the module terminator in the 9U expansion module terminator connection furthest from
the 5U library control module.
10 Connect the module-to-module cable from the 5U library control module to the 9U expansion module.
11 Connect an Ethernet cable to the Gigabit (GB) Ethernet port on the library control blade (LCB) for
remote access to the library via the Web client.
12 Connect a power cord to the outlet on the power supply on the rear of the library.
There should always be a power cord connected to the power supply on the 5U library control module.
If redundant power supplies are used, connect a power cord to each of the additional power supply
outlets.
13 Power on the library.
a. Turn on the rear power switch of each of the power supplies.
b. Turn on the front power switch.
c. Power up the host system.
14 Verify communication with all devices on the bus
15 Configure the library using the commands on the operator panel.
Recommended Library Cabling for FC I/O Blades
Fibre optic cables connect Fibre Channel tape drives to I/O blades and I/O blades to a Storage Area
Network (SAN) fabric or host. Correctly managing these cables on the rear of the library can prevent
damage to the cables and Fibre Channel ports and ensure optimal data throughput.
SAN-ready tape drives that are shipped with I/O blades include 24-inch fibre optic cables to connect drives
to initiator ports on an I/O blade. The short length of these fibre cables is intentional. Ideally, an installed
tape drive should be cabled to a port on the nearest I/O blade to eliminate the need to manage excessively
long cables. The nearest I/O blade is usually located in the same expansion module as the tape drive.
The 24-inch fibre cables are orange in color. You will need to provide fibre cables long enough to connect
a host or a SAN switch to a target port on an I/O blade.
It is important to consider how drives are assigned to partitions when cabling tape drives and hosts to an
I/O blade. If you want a host to be able to communicate with a tape drive that is assigned to a particular
partition, both the drive and the host that has access to the partition should communicate through the same
I/O blade.
Table 2 provides an example of a 41U library and ML6030 Control Module, plus two ML600 9U Expansion
Modules with I/O blade-attached tape drives. The information next to the image shows each tape drive and
the I/O blade and port to which each tape drive is connected.
CAUTION
The module terminator is not the same as a SCSI terminator. Using a
SCSI terminator instead of a module terminator will damage the
library.
