Replacing the WWN bezel and card The WWN card is located on the nonport side of the chassis underneath the WWN bezel (see Figure 2 on page 17). The WWN card is highly reliable, containing fully redundant circuits; it does not usually require replacement under normal operating conditions. If the WWN card does fail, the switch can continue operating until the new WWN card is installed if the configuration is not modified, no hardware components are replaced, and the switch is not rebooted. Replacing the WWN card requires a telnet session to the switch. The CLI can be either a telnet session or a serial console session; instructions are provided here for both. Identifying a failed WWN card The following indicators confirm that a WWN card needs to be replaced. NOTE: Check that the current card is firmly seated when performing the troubleshooting steps. • Visible mechanical damage to the WWN card • Any of the Status LEDs on the WWN card do not reflect the actual status of the components • Problems viewing or modifying the data stored on the WWN card • Error messages regarding WWN units #1 or #2 (see Table 17) To verify the status of the WWN card: 1. Check the LED indicators on the WWN bezel (see Figure 19 on page 77) and verify that they reflect the actual status of the components. The WWN bezel covers the WWN card and allows its LEDs to shine through. The LEDs on the WWN bezel provide a consolidated view of the 16-port card status, CP card status, and power supply status. For information about how to interpret the LED patterns, refer to Table 16. NOTE: The LED patterns might temporarily change during POST and other diagnostic tests.

Core Switch 2/64 and SAN Director 2/128 installation guide

Replacing the WWN bezel and card

The WWN card is located on the nonport side of the chassis underneath the WWN bezel

(see

Figure 2

on page 17). The WWN card is highly reliable, containing fully redundant

circuits; it does not usually require replacement under normal operating conditions.

If the WWN card does fail, the switch can continue operating until the new WWN card is

installed if the configuration is not modified, no hardware components are replaced, and the

switch is not rebooted.

Replacing the WWN card requires a telnet session to the switch. The CLI can be either a telnet

session or a serial console session; instructions are provided here for both.

Identifying a failed WWN card

The following indicators confirm that a WWN card needs to be replaced.

NOTE:

Check that the current card is firmly seated when performing the troubleshooting

steps.

•

Visible mechanical damage to the WWN card

•

Any of the Status LEDs on the WWN card do not reflect the actual status of the components

•

Problems viewing or modifying the data stored on the WWN card

•

Error messages regarding WWN units #1 or #2 (see

Table 17

)

To verify the status of the WWN card:

Check the LED indicators on the WWN bezel (see

Figure 19

on page 77) and verify that

they reflect the actual status of the components. The WWN bezel covers the WWN card

and allows its LEDs to shine through. The LEDs on the WWN bezel provide a consolidated

view of the 16-port card status, CP card status, and power supply status. For information

about how to interpret the LED patterns, refer to

Table 16

NOTE:

The LED patterns might temporarily change during POST and other diagnostic tests.
