Removable Power Supply and Fan

6

Installing a power supply unit or fan-only module

Before you begin:

Read the safety information for the switch.

Safety information is available in the Installation and Safety Guide that is on 
the CD-ROM for the switch. Or you can download this document from 

www.alliedtelesis.com/support/software

.

Gather necessary tools and equipment.

You may need a Phillips #2 screwdriver to adjust the retaining screws on a 
PSU or FOM. 

To install a DC version of the PSU, you need an appropriate DC power 
source, DC supply cable, ring connectors, and a crimp tool.

Verify the package contents if you have not already done so.

See 

“Package Contents” on page 4

. Contact your authorised distributor or 

reseller if items are damaged or missing.

1.

Unpack the power supply unit.

Caution

Follow correct anti-static procedures when installing either a PSU 

or FOM. Failure to do so could damage the PSU, FOM, or switch. If you are 
unsure about correct procedures, contact your authorised distributor or 
reseller.

While observing Electro Static Discharge (ESD) precautions, remove the 
PSU or FOM from its packing material in an anti-static environment.

2.

Disconnect the power supply from the power supply unit.

Warning

Disconnect the power cord before removing the PSU.

For AC models, turn off the main power supply to the PSU and disconnect 
the power cord.

For DC models, push the Run/Standby control and release it to the Off 
position using a small diameter pin. When the Run/Standby control is not 
depressed, it is off. Disconnect the supply cable wires from the circuit 
breaker. 

3.

For AC models only, install the power cord retaining clip.

There is one retaining clip for the AC power inlet on the PSU.
