HP StoreEver 1/8 G2 Tape Autoloader User and Service Guide (AK377-96024, December 2012)

3. Attach the other end of the parallel SCSI cable to the connector on the parallel SCSI host bus
adapter or to the connector on the previous device on the parallel SCSI bus.
NOTE: The host bus adapter should be Low Voltage Differential Signaling (LVDS). A
Single-Ended (SE) SCSI host bus adapter works, but severely degrades performance and limits
cable length. If any SE devices are on the same parallel SCSI bus, all of the devices on the
parallel SCSI bus slow to SE speed, which severely degrades performance. Never attach an
LTO-3 or LTO-4 tape drive to an SE SCSI bus.
4. Attach the terminator to the remaining parallel SCSI connector on the back panel of the tape
drive if the autoloader is the last or only device on the parallel SCSI bus. Otherwise, attach
one end of a parallel SCSI cable to the remaining port and the other end to the next device
on the parallel SCSI bus. Make sure the last device on the parallel SCSI bus is properly
terminated.
IMPORTANT: For the autoloader and tape drive to operate correctly, the tape drive must
have a SCSI terminator unless the tape drive is part of a properly terminated chain. This
includes tape drives without an attached SCSI cable.
Connecting the Fibre Channel cables (Fibre Channel devices only)
To connect the Fibre Channel cable to the autoloader:
1. Remove the FC port cap if necessary. Attach one end of the Fibre Channel cable to the Fibre
Channel port on the tape drive.
2. Attach the other end of the FC cable to a switch or HBA.
Connecting the SAS cable (SAS devices only)
To connect the SAS cable to the device:
1. Attach the HBA end of the SAS cable into the connector on the HBA.
2. Attach the other end of the cable into the connector on the tape drive.
TIP: Mini-SAS connectors are keyed. Do not force a SAS cable's mini-SAS connector into
the tape drive mini-SAS connector because it might be keyed differently.
NOTE: SAS signal rates require clean connections between the HBA and tape drive. Do not use
adapters or converters between the HBA and the tape drive. For reliable operation, use a maximum
SAS cable length of six meters.
Powering on the device
WARNING! This product can only be used with an HP-approved power cord for your specific
geographic region. Use of a non-HP-approved power cord may result in: 1) not meeting individual
country specific safety requirements; 2) insufficient conductor ampacity that could result in
overheating with potential personal injury and/or property damage; and 3) an unapproved power
cord could fracture resulting in the internal contacts being exposed, which potentially could subject
the user to a shock hazard. HP disclaims all liability in the event a non-HP-approved power cord
is used.
To power on the autoloader:
1. To use the web-based management interface, connect an Ethernet cable to a working LAN
connection and to the Ethernet connector on the back of the autoloader.
2. Attach the power cable to the power connector on the back panel of the autoloader (see
Figure 20 (page 27)).
