Determining the status of a power supply

Refer to Figure 37 and Table 27 for a map of the ports and a table of external ports to internal ports
as shown in the slotShow command.
Determining the status of a power supply
Complete the following steps to determine the status of a power supply.
1. Check the LED indicator on the power supply (see the following figure). The LED patterns may
temporarily change during POST and other diagnostic tests; for information about how to
interpret the LED patterns, refer to Table 6. The Brocade DCX 8510-4 has two power supplies.
Be sure to check each module.
2. Check the power supply status by entering psShow.
The power supply status displays OK, Absent, or Faulty. If a power supply displays absent or
faulty, contact the Brocade DCX 8510-4 supplier to order replacement parts. Both physically
absent or faulty could also be the result of the power supply not being properly seated or being
turned off.
Table 15 shows a power supply.
