1) The following events are detected as predictable errors:
The temperature is very high.
The power consumption is very high.
The strength of current is very high.
The fan speed is very low.
In each of these cases please notify Customer Support.
Assignment of the PCIe slots
The assignment of the PCIe slots differs between MU M1, MU M2 and MU M3.
PCIe slot assignment on an MU M1
Figure 30: Principle of PCIe slot assignment at the rear of the device (MU M1)
The figure shows the PCIe slots of the MU M1 on an SE700. On the various model series of the SE server, the PCIe slots of an MU M1 are assigned as follows:
PCIe slot | SE700 | SE500 | SE300 |
S1 | not assigned | not assigned | not assigned |
S2 | USB card | USB card | not assigned |
S3 | FibreChannel card | FibreChannel card | not assigned |
Table 2: PCIe slot assignment on an MU M1
The MU M1 can be equipped with a second FibreChannel card in the free PCIe slot S1. Accordingly, two more ports are available for the ROBAR connection and cluster functionality.
PCIe slot assignment on the MU M2
Figure 31: Principle of PCIe slot assignment at the rear of the device (MU M2)
The figure shows the PCIe slots of the MU M2 on an SE700B. On the various model series of the SE server, the PCIe slots of an MU M2 are assigned as follows:
PCIe slot | SE700B | SE500B | SE300B |
S2 | not assigned | not assigned | not assigned |
S3 | FibreChannel card | FibreChannel card | not assigned |
S4 | FibreChannel card | FibreChannel card | not assigned |
Table 3: PCIe slot assignment on an MU M2
The MU M2 can be equipped with another FibreChannel card in the free PCIe slot S2. Accordingly, two more ports are available for the ROBAR connection and cluster functionality.
PCIe slot assignment on the MU M3
Figure 32: Principle of PCIe slot assignment at the rear of the device (MU M3)
The figure shows the PCIe slots of the MU M3 on an SE710. On the various model series of the SE server, the PCIe slots of an MU M3 are assigned as follows:
| PCIe slot | SE710 | SE310 |
|---|---|---|
| S2 | FibreChannel card | optional FibreChannel card (→ CRD) |
| S3 | optional FibreChannel card (→ CRD) | optional FibreChannel card (→ CRD) |
| S4 | not assigned | not assigned |
Table 4: PCIe slot assignment on an MU M3
The MU M3 can be equipped with another FibreChannel card in the free PCIe slot S4. Accordingly, two more ports are available for the ROBAR connection and cluster functionality.
