9 Monitoring DC04 SAN Director system 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 • "Monitoring blower assembly status" on page 165 • "Monitoring WWN bezel (logo plate) and WWN card status" on page 167 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. HP StorageWorks DC and DC04 SAN Backbone Director Switches 153
