Tape Drive Rear Panel
22 T10000 Operator’s Guide • July 2008 Revision EA • 96174
Tape Drive Rear Panel
The rear panel (
FIGURE 1-2
) contains five connectors, two cooling fans, two tri-color LED
indicators, and a recessed push-button switch. The drive status LED is on all drives
while the encryption status LED is only on encryption-capable drives. The recessed
switch is used by service representatives to toggle the drive in/out of the service mode.
Note – See
TABLE 1-1 on page 23
for drive status LED states.
See
TABLE 1-2 on page 24
for encryption status LED states.
Interface Ports Use
The T10000 tape drive supports connection of both ports, in accordance with ANSI
Fibre Channel specifications (ref. InterNational Committee on Information Technology
Standards [INCITS] documents: SCSI Primary Commands -3, Section 5.6, and Fibre
Channel Protocol -3). The drive will support two hosts, providing that both hosts honor
the “reserve/release” and/or the “persistent reserve/release” specifications.
It is not recommended that a T10000 tape drive be connected to the same host bus port
with another tape or a disk subsystem. The stress on the host bus adapter, due to the
bandwidth needs, creates unacceptable error recovery issues between both solutions.
