Installing and Maintaining the C300 System 45

Removing and Replacing Components

This section provides instructions for removing and replacing the following C7008/C300 components:

• Removing and Replacing the Fan Tray

• Removing and Replacing Power Supply Units

• Removing and Replacing a Line Card

When a component fails, the C-Series 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

Appendix ,

for more information on alarms.

WARNING: Electrostatic discharge (ESD) damage can occur when components are mishandled. 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.

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 C-Series System will operate safely for approximately

two (2) minutes at an ambient temperature of 77° F (25° C).

To remove and replace the fan tray, you must be able 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.

WARNING: To ensure proper temperature and airflow control, the fan tray must always be installed.
