5.3 SFCS-1000 Fan Tray Replacement
The SFCS-1000 has a removable fan tray with large fans that cool the switch
hardware and power supply modules. Located at the base of the upright unit,
the fan tray is removable from the front of the unit and is hot-swappable,
meaning that it can be replaced with the SFCS-1000 under power. The proce-
dure for replacing a fan tray is as follows:
WARNING! It is highly recommended that you use the
included grounding strap when handling this,
or any other component.
1. Remove the four retaining screws at the top of the fan tray with a
3/32-inch Allen wrench.
2. Remove the fan tray by pulling it away from the switch unit.
3. Set the old fan tray aside and place the new fan tray in front of the
vacant slot in the SFCS-1000.
4. Insert a new fan tray in the slot and slide it all the way into the
chassis. Seat the connectors by pressing firmly on the unit (this
will apply power to the fan tray).
5. Once seated, replace the four screws removed in Step 1 above.
This will properly secure the unit in the chassis.
CAUTION Do not run the unit for any great length of
time without the fan tray installed or the unit
will shut itself down because of an overtem-
perature condition.
