VNX5700 Hardware Information Guide 79
LCC enclosure ID (enclosure address) and bus ID
On the rear of the LCC (A and B), an LCC enclosure ID indicator is provided. This ID
indicator is a seven-segment LED display for displaying decimal numbers. The LCC
enclosure ID appears on both LCCs (A and B) which is the same ID number. The enclosure
ID is set at installation (Figure 68).
Each LCC includes a bus (loop) identification indicator. This indicator includes two
seven-segment LED displays for displaying decimal numbers. The SP initializes the bus ID
when the operating system is loaded (Figure 68).
