1. Power Supply Status: Each AC power connector indicates the location of an
internal power supply. A simulated green LED indicator is located in the upper
left corner of each AC power connector. The indicator illuminates if the power
supply is working and receiving AC power.
When a red and yellow diamond ( ) displays on a power connector, like in
Figure 2–1 on page
case, the green indicator to the top left of the connector will not illuminate. When
the green indicator is on and no status symbol displays, the power supply is
operational. Note that the switch operates with one power supply failure, however
replace the power supply as soon as possible to retain redundancy.
2. Fan Status: Three dual-fan modules (six fans total) are installed in the edge switch
2/16. One module cools one power supply, one module cools the other power
supply, and one module cools the CTP card.
When the LED indicator on a fan module illuminates, as shown in the previous
illustration, and a red diamond ( ) appears over a module, the fan has failed or is
rotating insufficiently. Note that the switch continues to operate with one fan
failure. If two or more fans fail, replace them as soon as possible to avoid switch
damage.
