McDATA Sphereon 4500 Fabric Switch Installation and Service Manual

Ensure the switch reporting the problem is connected to facility AC

power. Inspect the switch for indications of being powered on, such

as:

• At the front bezel, an illuminated PWR LED (green)

or ERR LED (amber).

• Illuminated LEDs adjacent to Fibre Channel ports.

• Audio emanations and airflow from cooling fans.

Does the switch appear powered on?

YES NO

↓ Both power supply modules failed or the CTP card failed. Go

to MAP 0000: Start MAP on page 3-6. If this is the second

time at this step and a dual power supply failure is ruled out,

a CTP card failure is indicated. Replace the switch. Exit

MAP.

Inspect both power supply modules (with internal switch cooling fans)

at the rear of the switch.

Does inspection of a power supply and fan module (combined FRU)

indicate a failure? Indicators include:

• The amber LED is illuminated on one or both power supplies.

• One or more cooling fans are not rotating.

YES NO

↓ Go to step 7.

Visual inspection or an event code 300, 301, 302, 303, 304, or 305

indicates one or more cooling fans failed, and one or both power

supplies (combined FRUs) must be removed and replaced. Refer to

RRP 2: Redundant Power Supply on page 5-6.

• This procedure is concurrent and can be performed while switch

power is on.

• If multiple fan failures caused a thermal shutdown, connect the

switch to facility AC power after the power supply(s) are

replaced.
