HP StorageWorks ESL E-Series Tape Library Unpacking and Installation Guide (350800-011, May 2010)

Cabling the library
The following sections include procedures for cabling the library. These procedures will be slightly
different for the e2400-160 interface controller and Ultrium 460 drives, the e2400-FC 2Gb and 4Gb
interface controller and Ultrium 460-FC and 960 drives, and the e2400-FC 2Gb interface controller
and Ultrium 1840 and 3280 drives. The instructions for cabling each type of library are presented
below.
CAUTION:
Before cabling the library, make sure the library is powered off and that the main switches on the
power distribution unit are turned off (to the left).
Connecting drive cluster cables
To connect the drive cluster cables:
1. Verify that drive cluster power cables are already installed.
2.
Verify that the I
2
C communications cable (located to the right of each drive cluster) is connected
to the I
2
C connector on the cluster controller.
Connecting the cables for SCSI tape drives
An e2400-FC 2Gb or 4Gb interface controller connects to Ultrium 460-FC or 960 drives using FC
cables. ESL E-Series tape libraries are shipped with FC data cables and drive cluster Ethernet cables
installed and routed. An e2400-160 interface controller connects to Ultrium 460 or SDLT drives using
SCSI cables. Drive cluster Ethernet cables are installed and routed before shipment, but SCSI cables
must be installed on site. For each controller card, follow the associated instructions, presented below,
to connect the SCSI drive cables.
NOTE:
HP recommends that you have only one drive type per cluster, and that you complete any partially-filled
clusters before adding a new drive type to your library. Cabling and mapping will be easier and
more efficient in this case. While combining SCSI and FC drives in a single cluster is supported, it
requires the use of two interface controllers, and will result in unused interface controller ports.
If you choose to combine SCSI and FC drive types, see the mixed interface technical document on the
web for important information. Access the Technical documentation page from the ESL E-Series
libraries link found on http://www.hp.com/go/tape.
NOTE:
Each e2400-160 interface controller card ships with four SCSI cables, one Ethernet cable, and seven
sets of color coded tie wraps. FC cables are not provided. These parts will be needed for the following
procedures.
