Monitoring core switch blade (CR8) status
To determine the status of a CR blade:
1. Observe the LED indicators on the core switch blade (see Figure 28 (page 57)). The LED
patterns may temporarily change during POST and other diagnostic tests. For information
about interpreting the LED patterns, see Table 9 (page 55).
2. Verify the core switch blade status by entering the slotShow and haShow commands.
