Removing and Replacing Components
This chapter provides instructions for removing and replacing E1200 AC and DC components. It covers
the following topics:
• Removing and Replacing Fan Trays
• Removing and Replacing AC Power Supplies
• Removing and Replacing DC Power Supplies
• Removing and Replacing RPMs, Line Cards, or SFM3s
• Removing and Replacing the Air Filter
When a component fails, the E1200 system triggers major or minor alarm LEDs (located on the RPM),
sends events to the SNMP trap and show alarms table, and disables or changes component Status LEDs.
Refer to
Chapter B, Alarms for more information on alarms.
Removing and Replacing Fan Trays
In the event of a fan tray failure, signified by an amber LED, an SNMP trap, or major alarm event, the
entire fan tray must be replaced. If one or more fans within a fan tray fail, the system generates a minor
alarm and an SNMP trap.
The fan trays are hot-swappable. To remove or replace the fan tray, you must have access to the rear of
the chassis and be able to pull the fan tray completely out of the slot (at least 20 inches).
To remove or replace a fan tray:
Step Task
1 Prior to removing a fan tray, turn the screw latch counter-clockwise (with a flathead screwdriver) one quarter of a
turn to unlock the fan tray. (Figure 12-1) .
2 Grip the handle and pull the fan tray out approximately one inch from the chassis. Wait until the fan blades stop
rotating, then remove
WARNING: Keep fingers clear of rotating fan blades.
3 Prior to inserting a new fan tray, fully turn (with a flathead screwdriver) the screw latch counter-clockwise until
the fan tray latching mechanism retracts into the fan tray.
4 Insert the fan tray into the chassis. Guide the tray firmly into the slot until it stops and the handle end is flush with
the chassis rear.
5 To secure the fan trays into place, turn the screw latch clockwise to tighten the latching mechanism. (see
Figure 12-1 )
