3.1 Setting up the Fibre Channel Rack System
The ATTO Fibre Channel Rack System is a configurable 19” rack system with two bays to house the
ATTO FibreCenter 3400R and two bays to house power modules. The 1U rackmount enclosure provides
the flexibility to integrate the ATTO FibreCenter 3400R in pairs.
The following items are included with the ATTO
Fibre Channel Rack System:
❈ Up to two (2) ATTO FibreCenter 3400R
modules
❈ One (1) or two (2) power modules containing
independent cooling fans
❈ One (1) or two (2) AC shielded power
cord(s).
❈ Two (2) rackmount “L” brackets and (4)
screws for mounting the unit into the rack.
❈ Installation and Operation Manual
The main enclosure of the ATTO Fibre Channel
Rack System houses the FibreCenter 3400R
modules and power modules: two bays for
FibreCenter 3400R and two bays for power
modules.
The ATTO FibreCenter 3400R can be installed
into the ATTO Fibre Channel Rack System with
the FibreCenter facing the front or the back using
the “L”-brackets and mounting holes provided on
either end. The mounting holes on the “L”-
bracket fit a standard 19” rack, using a centered
1.25” (31.7 mm) hole pattern.
The power modules will slide into the ATTO
Fibre Channel Rack System enclosure in either of
the two bays on the end of the rack enclosure that
is closer to the backplane and farthest away from
the cooling vents in the sides of the rack
enclosure.

Air flow and cooling
The Fibre Channel Rack System cooling fans are
contained within the power modules. Each power
module contains two 8-CFM fans and provides a
total of 16 CFM of airflow. A system that has two
power modules installed will have a total of 32
CFM of airflow. Air enters through the sides of
the enclosure and is exhausted out the power
modules. Ambient air near the inlets should not
exceed 40° C.
WARNING
Do not block the vents on either side of the
main enclosure. Blocking the vents may cause
overheating and could damage the product.
Internal power distribution
The ATTO Fibre Channel Rack System provides
a redundant power scheme with two hot
swappable power supply modules. Each power
supply module feeds 12V to the backplane. Power
is distributed to the FibreCenter 3400R and the
fans from the backplane.
A failure of one power supply will not affect the
functionality of the FibreCenter 3400R or the
cooling system since the second supply would
continue to supply power to the backplane. If you
have two power supplies in the ATTO Fibre
Channel Rack System, one supply can be
removed and replaced without affecting the rest of
the system in any way.
The FibreCenter 3400R detects power supply
failures, voltage regulation and failover.
NOTE: Power modules will load balance
when there are two present in the ATTO Fibre
Channel Rack System
Input voltage:
110/230V AC, with an operating
input range of 90-132V AC or 175-264V AC, 47-
63Hz, single phase. The AC input range selection
is automatic. No manual jumper or switchover is
required.
