1–General Description 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

NOTE:

You can activate the Inter-Chassis Connection ports by installing the HyperStack license key. Refer to “HyperStacking” on page 3-29for information about HyperStacking switches.

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 5-16for 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.

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.
