Power Supply Blades

Serial Port
The serial port is an RJ-45 connector and uses a 10/100 Base-T Ethernet straight
cable with the RJ-45/RS-232 console adapter provided with the switch. You
manage the switch through the primary CPU blade serial port using the CLI.
Inter-Chassis Connection Ports
Each CPU has two Inter-Chassis Connection (ICC0, ICC1) ports with which to
establish a connection with another QLogic 9000 Series switch. Each ICC port is
a bundle of eight 10-Gbps Fibre Channel ports that log in to a second
QLogic 9000 Series switch. The ICC port Logged-In LEDs show the ICC port
connection status.
Power Supply Blades
The Power Supply blades convert standard 100 to 240 VAC to DC voltages for the
various switch circuits. After connecting a power supply to an AC voltage source
and placing the On/Off switch in the On position, the Power Supply blade is
energized. During normal operation, each Power Supply blade provides half of the
demand. If one Power Supply blade fails, the second Power Supply blade can
provide all of the switch power needs for a short time until the failed Power Supply
blade can be replaced. Refer to “Replacing Power Supply Blades” on page 5-16
for more information.
Power Supply blades are known to the switch firmware by their blade IDs and
blade types. The blade IDs (PS0, PS1) indicate the blade type and location in the
switch chassis. The blade types (PSFB, PSBF) indicate the blade type and air
flow direction. Air flow direction can be front-to-back or back-to-front. In addition to
the blade ID, a label on the body of the Power Supply blade indicates the air flow
direction.
NOTE:
You can activate the Inter-Chassis Connection ports by installing the
HyperStack license key. Refer to “HyperStacking” on page 3-29 for
information about HyperStacking switches.
CAUTION!
To prevent overheating and damage to switch circuits, Power Supply and
Fan blades must have the same air flow direction. The System Fault LED
will illuminate if the Power Supply and Fan blades do not have the same air
flow direction.
