An IGX-8 identifies itself as an IGX-32 on the configuration screen. What has gone wrong?

A.
The NPM was originally in an IGX-32

B.
Database corruption has occurred

C.
The user must physically set a jumper on the SCM to correct this

D.
Use the setnovram command to change the switch type

Explanation:

The SCM card determines whether the IGX node is an IGX 8410 (which has 8 slots), an IGX 8420 (which has 16 slots), or an IGX 8430 (which has 32 slots). Before installing cards in the node or replacing the SCM, verify that the jumpers are set properly. The two jumpers, W5 and W6, are located near the P2 connector and the strengthening bar on the SCM card. (See Figure 3-1.) Record your setting, so that you don’t have to remove the SCM card later to verify the setting.
