CAUTION:

DO NOT mix airflow directions. The airflow directions are color coded. A red label indicates that hot air is

expelled from the PSU and a blue label indicates that hot air is expelled from the I/O. Both power supplies must use the

same airflow direction (I/O to Utility or Utility to I/O). The power supplies and fans must have the same color strap. If

you mismatch the airflows, the following error message appears and the system shuts down:

00:02:19: %S5000:0 %CHMGR-2-PSU_TYPE_AIRFLOW_MISMATCH: Mismatching PSU airflow detected.

Unit 0 shall get shutdown in next 60 seconds if mismatch not rectified. 00:02:19:

%STKUNIT0-M:CP %CHMGR-1-PSU_AIRFLOW_COMBO_MISMATCH: Major alarm: Mismatching PSU airflow

detected in unit 0

Installing an AC Power Supply

1. Remove the PSU from the electro-static bag.

2. Use the grab handle to slide the PSU into the switch PSU slot (install the PSU-exposed PCB edge connector first). The PSU slot is

keyed so that the PSU can be fully inserted in only one way. When you install the PSU correctly, it snaps into place and is flush with

the back of the switch.
