Removing and Replacing Components
This section provides instructions for removing and replacing the following C7004/C150 components:
•
Removing and Replacing the Fan Tray on page 47
•
Removing and Replacing Power Supply Units on page 48
•
Removing and Replacing a Line Card on page 49
•
Removing and Replacing an RPM on page 49
When a component fails, the C7004/C150 System system triggers an alarm LED (located on the active
RPM), disables or changes component Status LEDs, and sends events to the SNMP trap and show alarms
table (if this feature is configured). Refer to
for more information on
alarms.
NOTE:
Always wear an ESD-preventive wrist or ankle strap when handling RPMs and line cards. Connect the
ESD strap to the grounding plug located on the front of the chassis. Place RPMs and line cards on an
antistatic surface and anti-static bags when they are not installed. Electrostatic discharge (ESD) damage can
occur when components are mishandled.
When a component fails, the C7004/C150 System system triggers major or minor alarm LEDs (located
on the RPM), sends events to the SNMP trap and show alarms table, disables or changes component
Status LEDs or triggers an audible alarm. Refer to
alarms.
Removing and Replacing the Fan Tray
A fan tray failure or a failure of a fan within a fan tray is recognized by a red fan tray LED, a lit RPM
alarm LED, and, if configured, an SNMP trap and alarm event. The failure requires a replacement of the
entire fan tray. While you replace the fan tray, the C7004/C150 system operates safely for approximately
two (2) minutes at an ambient temperature of 77° F (25° C).
To remove and replace the fan tray, you must have enough space to pull the fan tray completely out of the
slot (at least 20 inches).
WARNING:
Fan blades rotate at high speeds and may cause injury if touched. Adhere to the following
instructions to avoid possible injury.
NOTE:
The fan tray must always be installed to ensure proper temperature and airflow control.
To remove and replace the fan tray:
Step
Task
1
Unscrew the retaining screws at the top and bottom of the fan tray.
2
Use the handle to pull the fan tray out approximately two inches from the back of the chassis. Wait 30 seconds,
until the fan blades stop rotating, then completely remove the fan tray.
