ATTO Technology Inc. iPBridge Installation and Operation Manual
1.1 Physical components
The ATTO iPBridge 1550D is a 1-Gigabit Ethernet to Ultra 320 SCSI desktop bridge which produces a
cost-effective iSCSI solution for SMB/SME environments.
Dimensions
Width:
7.5 inches wide
Depth:
5.0 inches long
Height:
1.76 inches
Environment
Operating Temperature: 0-70 °C external
Ambient air
should not exceed 40 °C
Humidity:
10-90% non-condensing
Power
The iPBridge 1550 uses a 12-volt power brick
connected to an appropriate power source. The
power source must be connected to a protective
earth ground and comply with local electrical
codes. Improper grounding may result in an
electrical shock or damage to the unit.
Input voltage:
12v@1.5A
100-240 VAC, 0.5A@100v, 47-63 Hz
SCSI port
The SCSI port is an Ultra 320 LVD/SE SCSI bus
with 68-pin “P” interface; downward compatible
with all forms of low voltage differential and
single-ended SCSI.
Ethernet port
The 10/100/1000 GbE RJ-45 Ethernet port uses
the Intel 8254x family gigabit Ethernet chipset to
support iSCSI data transfer and inbound
management. GbE cables must be at least CAT-
5E certified.
Serial port
An RS-232 serial port provides support for remote
monitoring and management. The serial port is set
at the factory at 115,200 bps.
Reset switch
A manual reset switch is mounted on the back
panel. Insert a tool in the hole in the back panel to
activate the switch, wait until the Activity LED on
the top of the iPBridge becomes green, then cycle
power. The iPBridge is reset to factory defaults
LED indicators
Ready/SCSI Port Activity:
a green LED on the
top and on the back of the iPBridge lights solid
green to indicate ready and blinks to show SCSI
activity and to identify the iPBridge when
commanded by software.
Ethernet port:
two LEDs are integrated into the
Ethernet connector. One lights solid green to
denote a complete link and blinks green to show
activity. A bicolor green/yellow LED lights
yellow to indicate 1 Gb/sec. transmission speed
and lights green to show 100 Mb/sec. speed.
