ment Fan Tray:

Warnings

●Make sure that all AC power is disconnected from the switch

before starting the procedures described in this guide. Do not

reconnect the power until the switch is completely reassembled

and cover plates are replaced on any open module slots or power

supply bays.

●If your switch is rack mounted, make sure that the rack is not going

to tip over as you complete these procedures. If the switch is

difficult to reach, remove it from the rack or other mounting

location before proceeding.

Cautions

●When handling the switch modules, the fan tray, and the fan tray connec-

tor, do not touch the components or edge connectors on any printed

circuit boards, or the pins on any connectors. Otherwise, damage due to

static discharge could occur.

●Refer to the installation guides that came with your switch and switch

power supply for precautions on proper handling and installation of the

switch and power supplies. For copies of the installation guides, visit the

Installing the Replacement Fan Tray

Overview

The installation steps are:

1. Disconnect all AC power from the switch and remove any power supplies and

cover plates.

2. On the front of the switch, mark or otherwise note the location of the network

cables attached to the network modules in switch slots A and B so that you can

reconnect the cables to the correct ports at the end of this procedure. Then,

disconnect all network cables from modules that are installed in slots A and B

on the front of the switch.

Alternatively, if you have sufficient slack in the cables, you can leave the network

cables connected to the modules as you complete the next step.

3. Remove the Management module and any modules that you have installed in

slots A and B. (Remember which module is located in which slot).

4. Remove the old fan tray assembly.

5. Install the Replacement Fan Tray.

6. Reinstall the Management module into its slot and the network modules into

their previous positions in slots A and B. (Make sure you do not overtighten the

screws on the modules.)

7. If you disconnected the network cables in step 2, reconnect the cables to the

correct ports on the network modules.

8. On the back of the switch, reinstall the power supply or supplies and cover plates.

9. Reconnect the AC power to the power supplies.

10. Verify that the switch is operating correctly by observing the LEDs on the front

of the switch.

5. Install the Replacement Fan Tray. Follow these steps:

a. Insert the new fan tray into the back of the switch so that it matches the position

of the old tray. (The tabs that stick out from the sides of the switch chassis fit

into the slots in the corners of the fan tray, as shown in the illustration.)

b. Make sure the fan tray cable connector is on the front side of the switch

backplane, and then pivot the fan tray upward.

Tabs on the switch fit into

the slots in each corner

b. Install and tighten the two screws that hold the fan tray in place. (Make sure

you do not overtighten the screws.).

Caution: Make sure you do not leave any loose screws or other

foreign material inside the chassis.

c. From the front of the switch, reach into the opening made by the removed

modules and connect the fan tray cable to the white 9-pin connector on the

switch mother board by pressing it straight onto the connector, all the way in

until it stops.

module edge connector, as shown in the illustration.

Tighten the two screws

just until they are snug.

Align the fan tray cable connector

with the corner of the large connector

on the switch board. Then press the

cable connector straight onto the

white 9-pin connector in that location.

reinstall the power supply or supplies, and cover plates.

Caution: Make sure that AC power is disconnected from the power

supply before installing the power supply into the switch.

9. Reconnect the AC power to the power supplies.

Lower the power supply into

the opening and push it all the

way back until it connects with

the switch power connector.
