3Com Switch 4050 and 4060 — Rear View Detail

19

WARNING:

The system must not be left without a power supply or a 

blanking plate in either of the two slots (except during replacement of 
the power supplies). Tighten all screws with a suitable screwdriver.

WARNING:

Care must be taken when removing a PSU as it may be hot. 

The replacement of power supplies should be completed within two 
minutes to avoid normal cooling being disturbed.

Power Socket

Each Power Supply automatically adjusts its power setting to any power 
voltage in the range 90-240 VAC.

WARNING:

Mains power must be removed from the PSU before 

removing the PSU. A PSU must only be powered once it has been 
installed.

Replaceable Fan Trays

The 3Com Switch 4050 and 4060 are provided with two identical fan 
trays which can be replaced. Contact your supplier for further 
information. For information on installation, please refer to the 
documentation that accompanies your fan tray.

The 3Com Switch 4050 and 4060 support the 3Com Fan Tray (3C17717).

WARNING:

A fan tray can be temporarily removed and replaced while 

the system is running without impacting operations. The system must not 
be left with either fan tray removed for more than two minutes or 
damage to the product may be caused. Tighten all screws with a suitable 
screwdriver.

WARNING:

Care must be taken when removing the fan tray as the fan 

blades may continue to spin for a short time after removal. Keep fingers 
clear.

CAUTION:

You are advised to replace a failed fan as soon as possible. 

Although the unit will continue to operate after a single fan failure its 
airflow and temperature will be affected.

 

In such circumstances, the unit 

may overheat and automatically shutdown. If the unit continues to 
operate with reduced airflow, its long term reliability will also be reduced.
