Chapter 1: CN1610 Switch Features 9
The following table describes the Speed and Link/Activity LEDs found above the
remote management port:
Power supplies The CN1610 has two internal, replaceable AC power supplies for redundant or
load-sharing operation. Each power supply can provide 300 watts and includes
hot-swap support.
Each power supply receives power by connecting an AC power source to the
power socket on the rear panel of the switch.
Although the cluster network switch has redundant power supplies and can
operate normally when only one power supply is installed and operational, IBM
recommends that you replace any failed power supply immediately to maintain
redundancy. If one power supply fails, a second power supply must be present
and functional for the switch to continue to operate.
Fan units The two fan trays in the CN1610 support hot-swapping and can be removed or
inserted from the front panel. Each fan tray includes two fans. For the switch to
maintain an acceptable operating temperature, both fan trays must be present in
the chassis, and all four fans must be operational.
