The shelf ID switch and appliance and disk shelf loop switch are between the
CPU modules.
The illustration in Figure 4 shows the CPU module ports. Next, we describe
installing the N3700 cluster.

Connections and cabling
After unpacking and mounting the N3700 and all EXN2000s in a 19” rack, we first
install the base unit (two CPU modules), and then we describe the attachment of
the EXN2000 units. Perform the following steps:
1. Make sure that the N3700 system and its EXN2000 units are turned off.
2. Set the shelf ID of the N3700 base unit to 1 (Figure 5).

Important: The power to N3700 must be turned off before changing the
shelf ID.
