Network requirements
The library supports an independent customer network.
It is the customer’s responsibility to provide the proper length Ethernet cable for this connectivity.
The base module controller card has two Ethernet ports, which offer primary and redundant customer
network connectivity. See “Rear panel” on page 8.
These connections allow remote viewing and management of the library with the Management GUI.
Note: Have your network settings handy to use for entering on the Operator Panel. Your network settings
can also be stored as hardcopy on Appendix A, “Library Conguration Forms,” on page 146.
The secondary Ethernet port might be used for service. Three models are available for connection:
• No Ethernet port - Service personnel can connect a laptop to the customer network to use the
Management GUI.
• Dedicated secondary Ethernet port - The secondary network port that is dedicated only for service
personnel to connect a laptop directly to the library.
• Secondary Ethernet port - The secondary network port can be disconnected and service personnel can
use it to connect a laptop directly to the library.
IP range selection
For internal communication between modules, the tape library uses an Ethernet connection with an
internal IP address range. To prevent any conflict between the internal IP address range and the external
IP addresses, you must select the internal IP range. Choosing the Internal IP address range, and also
entering the external IP address information is part of the initial setup of the library.
Host requirements
The library requires attachment to supported SAS or FC HBAs.
The library requires attachment to supported SAS or FC HBAs. See “Host connectivity” on page 20.
Static Sensitive
Risk of damage to devices
• A discharge of static electricity damages static-sensitive
devices or micro circuitry.
• Proper packaging and grounding techniques are necessary
precautions to prevent damage.
Follow these general guidelines.
• Check with a system administrator before the host computer is powered off.
• For a SAS library, conrm availability or install a SAS HBA that supports multiple LUNs.
• For a direct-attach Fibre Channel library, conrm availability of installation of an FC HBA.
• For connection of a Fibre Channel library through a compatible switch, verify that sufcient ports are
available.
Persistent binding to ensure SCSI ID assignment
When a server is booted, devices are discovered and assigned SCSI target and LUN IDs. It is possible for
these SCSI assignments to change between boots. Some operating systems do not guarantee that
devices are always allocated the same SCSI target ID after rebooting. Also, some software depends on
