PURPOSE

shelf.
PREREQUISITES
Read the following bullet list before starting this procedure.
•
Although this procedure is normally done to replace a failed (inactive) component,
always verify component state before removal.
GENERAL

location and address.
STEP
PROCEDURE
1
DANGER: Possibility of personal injury. Modules can be installed or removed with
bay power on. Hazardous electrical potentials are present; use extreme care when
installing or removing modules with power on.
2
WARNING: Possibility of equipment damage. Operating a 1677 SONET Link
shelf for more than 3 minutes with the fan-tray assembly removed or not
functioning properly, will cause the shelf to overheat and disrupt traffic.
Make sure the replacement fan-tray assembly is close by, unpacked, and ready to
install immediately. Also, check the outer edge of the replacement fan-tray assembly
to make sure the EMI gasket is in place and not damaged.
3
DANGER: Possibility of personal injury. Keep fingers away from the rotating fan
blades. Pull the fan-tray assembly by the thumbscrews only. Wait for the fan blades
to stop spinning before attempting to remove the fan-tray assembly completely
from the chassis.
4
Loosen four captive screws on front of fan tray assembly.
5
Carefully slide out fan assembly.
6
Line up replacement fan assembly with rails in the shelf.
7
Slide replacement fan assembly into place.
