The fan trays in the HP 5900AF-48XG-4QSFP+, 5900AF-48XG-4QSFP+ TAA, and
5900AF-48G-4XG-2QSFP+ switches must be the same type: LSWM1FANSC or LSWM1FANSCB.
The fan trays in the HP 5900AF-48XGT-4QSFP+ switch must be the same type: LSWM1HFANSC or
LSWM1HFANSCB.
• When LSWM1FANSC/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 Figure 55.
