QFX5110 AC Power Specifications
Table 43 on page 158 describes the AC power specifications for QFX5110 switches. The typical and
maximum power consumption values are calculated using small form-factor plus (SFP+) direct attach copper
(DAC) cables on all network ports and all 100GBASE-SR4 transceivers in the uplink ports. Traffic is run at
25° C ambient.
