This section covers installation of the Dell PowerVault 136T SNC, SCSI devices,
and the host adapter.
Pre-Installation
It is important that the items in this list are verified before you begin
the installation of the SNC. This ensures a successful installation of the product.

1
Verify host platform OS required Service Pack installed.
For example: Microsoft® Windows NT® 4.0, Service Pack 6a (or later)
For a current list of supported platforms required host
platform code updates and information on how to obtain them, visit Dell
Support.
2
Verify required FC HBA, HBA BIOS, and Device Driver
are procured and installed.
For a list of supported HBAs and the required BIOS and device
driver, visit Dell Support.
3
Ensure that all host FC cables:
Have been ordered with the product or have been pre-installed and
checked.
Are marked with:
Host system identifier
Library system identifier
Refer to the HBA Specification provided with
your HBA.
4
Mark both ends of each SCSI cable with the drive ID and
SNC connector number.
None.
5
Decide on network parameters. Ethernet
port configuration decisions:
Static IP address____________
Netmask (if required)_________
User-defined Dell PowerVault 136T library name (optional)__________________
If the library is not on the same TCP/IP subnet as the server, assign
the default network gateway address and/or route table entries. ________________________
NOTICE: Save this configuration information
for future reference.
Obtain the network
parameters from your network administrator.
NOTICE: Use of incorrect network parameters
can cause problems on the Ethernet network.
The default network name is SNC. If you choose a different name, it becomes
the prompt displayed on the service terminal. Choosing a different name
may be useful if you have more than one library.
Installation
The procedure bellow instructs you on how to install the SNC. You may have
the option of having a service representative perform this portion of the installation
for you.
Acquire information for Ethernet installation.
Insert the SNC in the empty bay of the library. Align the power connection
and seat unit firmly. Tighten the two thumbscrews. See Figure
1.

Cabling the SNC to One Tape Drive
In this configuration, SCSI bus 1 is connected to the library SCSI interface
and tape drive 1. Channel zoning is not typically used when a single channel
is cabled.
Locate two SCSI cables and one terminator.
Connect the SCSI cables and terminator as shown in Figure
2.

Cabling the SNC to Two Tape Drives
In this configuration, SCSI bus 1 is connected to the library SCSI interface
and tape drive 1 and SCSI bus 2 is connected to tape drive 2.
Locate three SCSI cables and two terminators.
Connect the SCSI cables and terminators as shown in Figure
3.
In this configuration, SCSI bus 1 is connected to the library SCSI interface
and tape drive 1 and SCSI bus 2 is connected to tape drive 2 and tape drive
3.
Locate four SCSI cables and two terminators.
Connect the SCSI cables and terminators as shown in Figure
5.

Cabling the SNC to Four Tape Drives
In this configuration, SCSI bus 1 is connected to the library SCSI interface,
tape drive 1, and tape drive 2 and SCSI bus 2 is connected to tape drive 3 and
tape drive 4.
Locate five SCSI cables and two terminators.
Connect the SCSI cables and terminators as shown in Figure
6.

Cabling the SNC to Five Tape Drives
In this configuration, SCSI bus 1 is connected to the library SCSI interface
and tape drive 1; SCSI bus 2 is connected to tape drive 2 and tape drive 3;
and SCSI bus 3 is connected to tape drive 4 and tape drive 5.
Locate six SCSI cables and three terminators.
Connect the SCSI cables and terminators as shown in Figure
7.

Channels
Cabling the SNC to Six Tape Drives
In this configuration, SCSI bus 1 is connected to the library SCSI interface
and tape drive 1; SCSI bus 2 is connected to tape drive 2 and tape drive 3;
SCSI bus 3 is connected to tape drive 4 and tape drive 5; and SCSI bus 4 is
connected to tape drive 6.
Locate seven SCSI cables and three terminators.
Connect the SCSI cables and terminators as shown in Figure
9.

Configuring the SNC
This section provides information for configuring your tape library for use
in a SAN.
Connect with HyperTerminal to the SNC using a null modem cable. Use the
following settings:
Baud: 19,200
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: X on/X off
Power on the library and observe the startup messages in HyperTerminal.
The SNC will complete initialization and display a command prompt in the form
of the serial number and a '>' (ex: 600023 >)
when it is ready to receive commands.
Issue the initializeBox command. This will
require a reboot of the library.
Once the library has finished rebooting, set the IP address for the SNC
by issuing the following command at the HyperTerminal prompt:
ethAddrSet "IP address", "Subnet Mask"
replace "IP address" and "Subnet Mask" with the appropriate
values.
Issue the ethEnable command to enable the Ethernet
port on the SNC.
Start the SNC Manager server application. This is found on the Start
Menu under Start-> Programs-> Dell PowerVault SNC Manager->
Server.
Start the SNC Manager client application. This is found on the Start
Menu under Start-> Programs-> Dell PowerVault SNC Manager->
Client.
Restart the library.
It may be necessary to configure your host-based LUN management software
to access the library.
Other Installation Issues
After you have completed installation, check the following items before using
your SNC.
Power-Up and Boot Sequence Guidelines
Before you reboot the library, you must stop all I/O between the host and
SCSI devices.
The SNC scans the SCSI buses when it boots. If you add or remove SCSI devices
after the library has booted, it will not detect the changes.
Before you turn on or restart the hosts that are connected via FC to the
library, you must wait until the SNC has finished booting. You will know that
the SNC has finished booting when the RDY LED on the user panel blinks at
intervals of one second.
Some operating systems provide you with software methods that allow you
to add or remove SCSI devices dynamically after the host has booted. To ensure
reliable operation, reboot the host.
If you update SNC firmware, you must reboot in order to use the new firmware.
To ensure compatibility between the firmware features or functions and the
host, reboot the host.
If you update SCSI device firmware, the SNC Manager client application
and the service terminal does not display the new firmware version until the
SNC has issued a SCSI inquiry. The SCSI Inquiry occurs when it rescans the
SCSI buses.
SNMP
The SNC implements an SNMP agent to communicate with the firmware. To customize
the SNC's SNMP configuration, refer to the snmpHelp
command.
