TAA cooling system
You must install two fan trays of the same model for the HP 5930-32 QSFP+/HP 5930-32 QSFP+ TAA
and HP 5930-2Slot+2QSFP+/HP 5930-2Slot+2QSFP+ TAA switches: LSWM1HFANSC or
LSWM1HFANSCB.

When the LSWM1HFANSC fan trays are used, cool air flows in through the air vents in the fan tray
panel and the power supply panels, circulates through the chassis and the power supplies, and
exhausts at the network port side, as shown in
When the LSWM1HFANSCB fan trays are used, cool air flows in through the air vents in the
