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
in this guide). 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 SAN Director 2/128 can continue operating until
the new WWN card is installed if the configuration is not modified, no hardware
components are replaced, and the SAN Director 2/128 is not rebooted.
Relacing the WWN card requires a telnet session to the SAN Director 2/128. 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 16
)
To verify the status of the WWN card:
1.
Check the LED indicators on the WWN bezel (see
Figure 19
) 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 15
.
Note:
The LED patterns might temporarily change during POST and other diagnostic
tests.
