58 Edge Switch 2/24 Service Manual

A dual power supply failure is not confirmed. Replace both original power

supplies to avoid the cost of expending replacement FRUs. Continue to the next

step.

One or both power supplies appear operational, but the CTP card is not receiving

DC power. The in-card circuit breaker may have tripped due to a power surge, or

the CTP card failed.

Disconnect both power cords, then reconnect the power cords (power cycle the

switch) to reset the CTP card.

Did power cycling the switch solve the problem?

NO YES

↓ The switch appears operational. Exit MAP.

Analysis for a CTP card failure is not described in this MAP. Go to “MAP 0000:

Start MAP” on page 32. Exit MAP.

Is fault isolation being performed at the EWS interface?

YES NO

↓ Fault isolation is being performed at the HAFM appliance. Go to

step 23.

Does the EWS interface appear operational?

NO YES

↓ Go to step 22.

A Page cannot be found, Unable to locate the server,

HTTP 404 - file not found, or other similar message appears. The

message indicates the PC cannot communicate with the switch because:

■ The switch-to-PC Internet link could not be established.

■ AC power distribution in the switch failed, or AC power was disconnected.

■ The switch CTP card failed.

Continue to the next step.
