System Clocks

System Clocks

A clock synthesizer on the main logic module is the master clock source. This source provides a number of output clocks that are further distributed to the system components as needed.

The clock distribution system is self-contained within each cell. Systems with multiple cells do not provide redundant system clocks.

EXPRESSSCOPE® Monitor

Each cell contains an EXPRESSSCOPE® Monitor on the front of the cell. The EXPRESSSCOPE® Monitor provides a control and display interface (LCD) for the cell and the partition containing that cell. It is primarily used to

yView and update network settings for the partition.

yView and update network settings for the cell.

yEnable the trusted platform module (TPM) physically present attribute. The EXPRESSSCOPE® Monitor consists of

yLCD display screen of four lines that are 20 characters each.

yNavigation buttons (up, down, left, and right) and a selection button (OK).

yPower button.

yCell identification (ID) button that specifies the cell in the display screen and lights the cell ID LED on the back of the cell. The ID button on either the front or back of the cell turns off the chassis identification.

yTwo LEDs-a cell status LED that is used by management firmware and a Service Processor fault LED that is used by the power subsystem.

Figure 2-13 illustrates the EXPRESSSCOPE® Monitor.
