Fan failure (action code 1):
This service action is due to a customer call
regarding a hub message to the system that indicates a fan failure has occurred or
you suspect a fan failure for another reason. Replace the Fibre Channel hub. See
“Working with the Fibre Channel hub” on page 110.
All ports fail to communicate (action code 2):
This service call is due to a
complete failure (no data can be passed through the hub).
1. Observe the front of the Fibre Channel hub. If the ready LED is on and steadily
green, see “Abnormal port LED/Function (action code 3)”.
If not, verify the following:
a. The power cord is seated.
b. There is power in the electrical outlet.
DANGER
An electrical outlet that is not correctly wired could place hazardous
voltage on metal parts of the system or the products that attach to the
system. It is the customer’s responsibility to ensure that the outlet is
correctly wired and grounded to prevent an electrical shock.
(72XXD201)
2. If the LED is now on, unplug the unit from the electrical outlet, wait 15 seconds,
then plug the unit into the electrical outlet.
3. If the ready LED is not on and steadily green, replace the entire 3534 Managed
Hub. See “Working with the Fibre Channel hub” on page 110.
Abnormal port LED/Function (action code 3):
You are here for one of the
following reasons:
v
You started from the action code for a total hub failure, and observed the ready
LED was functioning normally
v
The customer reported that only some ports were failing while others were
operating.
v
You observed an abnormal LED status on one or more ports.
Be sure that all cables and GBICs are properly seated. Observe the LEDs for the
failing ports. If you do not know which ports are failing, go to “Checking the Fibre
Channel hub” on page 30.
