The power supplies are 1U, 48V, 1200W

The supplies provide regulated +48V DC to all other modules in the system.

Each power supply has self contained fans for cooling.

Fan Trays

Refer to “Installing a Fan Module” on page 41 for installation instructions.

The fan trays are redundant, hot-swappable cooling units.

Only one fan tray, in either of the two slots, is required to cool the system. However, a blanking panel is required for any unused bay.

The replacement of any one fan tray does not disrupt the operation of the device in any way, and can be successfully completed without having to remove the device from a rack, or disconnect any cables.

The fan modules use DC Voltage regulators to control fan speed and contain a hardware fan control circuit, which controls and monitors the fan speed.

The fan module will default to full speed after a power-on or reset condition.

If one the fans fails, the redundant fan will go to full speed (if one is available).

CAUTION: The fan modules do not have guards. Do not remove a fan module completely from the bay until the blades have stopped moving (approximately 15 seconds).

Management Interface Modules

See Figure 1-2 on page 14 for a diagram of the chassis.

Refer to “Installing a Management Interface Module” on page 50 for installation instructions.

The Topspin 270/Cisco SFS 7008 supports redundant, hot-swappable Management Interface modules, each of which is paired to one of the Fabric Controller Core modules.

The Management Interface modules provide the following functions:

RS-232 serial console port

10/100 Ethernet management port

System real time clock (RTC)

Intra-system Ethernet switch, which provides a system configuration management data-path to all fabric modules.

Provide mirrors of the LED indicators from the front side of the chassis for the power supply, fans, and over-all system status. (refer to “Management Interface Module LEDs” on page 73).

Rack Alarm Connection (refer to “Rack Alarm” on page 19).
