4 Setting up the FC Rack System
The ATTO FC Rack System is a configurable 19-inch rack system with two bays designed to house the
ATTO FibreCenter 3400. The 1U rackmount enclosure provides the flexibility to integrate the
ATTO FibreCenter in pairs.
The following items are included with the ATTO
FC Rack System:
❈Up to two (2) ATTO FibreCenter modules
❈One (1) or two (2) power modules.
❈One (1) or two (2) 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.
The main enclosure of the ATTO FC Rack System
houses all the FibreCenter modules and power
modules: two bays for FibreCenter and two bays
for power modules.

Mounting
You can install the ATTO FC Rack System with
ATTO product modules 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-inch rack, using a
centered 1.25-inch (31.7 mm) hole pattern.
Air flow and cooling
The FC Rack System cooling fans are contained
within the power module. 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 FC Rack System provides a redundant
power scheme with two hot swappable power
supply modules. Each power supply module feeds
12V to the backplane. From there the power is
distributed to the FibreCenter 3400 modules and
the fans.
A failure of one power supply will not affect the
functionality of the modules or the cooling system
since the second supply will continue to supply
power to the backplane. In a redundant power
supply installation, one supply can be removed
and replaced without affecting the rest of the
system in any way.
The product module will detect power supply
failures, voltage regulation and failover.
NOTE: Power modules will load balance
when two are present in the ATTO FC Rack
System
The power module is a hot swappable unit that
contains enough power to supply two ATTO
product modules and four cooling fans. Each is
designed to slide into the ATTO FC Rack System
enclosure in either of the two bays on the end of
the rack enclosure that is closer to the backplane
and farther away from the cooling vents in the
sides of the rack enclosure.

Input voltage:
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 switch over is
required.
