CAUTION: Verify that the airow direcon on the power supply handle matches the
direcon of airow in the chassis. Ensure that each power supply you install in the
chassis has the same airow direcon. If you install power supplies with two dierent
airow direcons, Junos OS raises an alarm, and the fault ALM LED blinks amber. If you
need to convert the airow paern on a chassis, you must change out all the fans and
power supplies at one me to use the new direcon.
Table 12 on page 30 shows the dierent power supplies and their direcon of airow.
