Cell Identification

Cell Identification

Each cell in a system has a unique physical cell identifier-cell 0, cell 1, cell 2, or cell 3. The management firmware uses the cell identifier to enable the cells within the system to communicate with each other.

The cell identifier is established by the interconnect cables. The cell identifier is based on which ends of the interconnect cables are connected to the interconnect ports on the back of the cell. Each interconnect cable has an "A" and a "B" end. Table 3-1 shows which cable end needs to be connected to the interconnect ports to create specific cell IDs.

Table 3-1 Relation of Interconnect Port and Cable End to Cell ID

Cell ID	Port 2	Port 1	Port 0
Cell 0	B	B	B
Cell 1	B	A	A
Cell 2	B	A	B
Cell 3	A	A	A

A cell without any cables connected to the interconnect ports is assumed to be cell 0.

To allow the correct cell identifier to be saved, a system must be completely cabled before the AC power is applied to the cells for the first time. Once established, the cell identifier is static.

The cell identifier is shown on the same label as the system serial number. See Figure 3-4 for the location of the label.

System Serial Number

The system serial number uniquely identifies each system. All cells within a system share the same system serial number.

A label with the system serial number is attached to each cell. Figure 3-4 shows the label location in the cell.
