ATTO Technology Inc. iPBridge Installation and Operation Manual
1.1 ATTO iPBridge 2500R/D
The ATTO iPBridge 2500R/D is a 1-Gigabit Ethernet to SCSI 1U full-rack bridge for midrange high
performance, cost effective solutions in enterprise environments.
The iPBridge 2500R/D includes a single power
supply, two Ethernet data ports, an Ethernet
management port which may be used as a data
port in the iPBridge 2500 iSCSI-configured
model, a serial management port and two SCSI
data and management ports. It includes a battery-
backed Real-Time-Clock, and an IP Time client
(RFC 1631 compliant).
Designed to fit into a 1U, full-rack enclosure, the
iPBridge 2500R/D supports side mounting so it
may be mounted into a standard 19-inch rack. The
ports and AC power are accessed from the rear of
the unit while LEDs showing port activity and
status are in the front and rear.
Dimensions
Width:
16.91 inches wide (42.95 cm)
Depth:
10 inches deep (25.4 cm)
Height:
1.72 inches high (4.32 cm (1U)
Weight:
approximately 2 pounds
Environment
Operating temperature:
0-70° C external
Ambient air should not exceed 40°C.
User-configurable thermal sensor for automatic
shutdown default is 70°C
Blower and airflow:
air enters through the slots in
the rear panel and exits through the blower on the
far end of the rear panel.
Humidity:
10-90% non-condensing
Power
Internal power supply:
single-output 5VDC, 25-
watt open frame switching power supply with
universal input via a standard IEC320 adapter
mounted within the enclosure. Provides power for
the board and the cooling fan and is not hot
swappable.
Input voltage:
120-240VAC, 50-60 Hz, fused on
the power supply.
Power draw:
4 amps at 5.0V DC.
Battery-backed event log SRAM:
A rechargeable
Lithium ion battery cell holds the memory in a
512KB SRAM for up to 30 days. If the iPBridge
has been disconnected from power, recharging
begins automatically when power is restored to
the system. The battery is fully charged after 36
hours of continuous power application.
WARNING
Risk of explosion if battery is removed
and/or replaced by an incorrect type.
Dispose of used batteries in accordance
with your local environmental regulations.
SCSI interface
The two independent SCSI ports on the iPBridge
2500R/D connect storage devices into the
Ethernet Storage Area Network (SAN). Each port
is completely independent from the other.
The ports are Ultra 3 LVD/SE SCSI busses with
68-pin “P” interface: 160 MB/sec. maximum
throughput, downward compatible with all forms
of single-ended SCSI.
The iPBridge supports all SCSI devices including
hard disk drives, tape drives, RAID controllers
and DVD, MO and CD libraries.
Ethernet interface
The two independent 10/100/1000 Ethernet RJ45
data ports, labeled Ethernet ports 0 and 1, use the
Intel 8254x family gigabit Ethernet chipset to
support telnet-based data transfer. A separate
10/100/1000 Ethernet standard RJ45 management
port, labeled Ethernet port 2, provides monitoring
and management through a command line
interface or ATTO ExpressNAV, a browser-based
interface. It may be used as a data port in the
iPBridge 2500 iSCSI-configured model.
GbE cables must be at least CAT-5E certified for
1000 Mb/sec. use.
