components
This chapter provides the following information on interpreting LEDs to monitor the following DC04
SAN Director components:
• “Monitoring Director blade status” on page 153
• “Monitoring Control Processor blade (CP8) status” on page 160
• “Monitoring core switch blade (CR4S-8) status” on page 162
• “Monitoring power supply status” on page 164

Introduction
The DC04 SAN Director is engineered for reliability and requires no routine operational steps or
maintenance. This chapter provides information about determining the status of each component using
LEDs and CLI commands.
Monitoring Director blade status
To determine the status of a Director blade:
1. Check the LEDs on the blade.
• Figure 52 shows the FC8-16
• Figure 53 shows the FC8-32
• Figure 54 shows the FC8-48
• Figure 55 shows the FC10-6
• Figure 56 shows the FR4-18i
2. The LED patterns may temporarily change during POST and other diagnostic tests. For information
about how to interpret the LED patterns, see Table 30.
3. Type slotShow to check blade status.
Table 30 on page 159 describes the Director blade LED patterns and the recommended actions
for those patterns.
