The airflow direction depends on the fan modules and power supplies installed in the switch. You can order a QFX5120 switch that supports front-to-back airflow (air enters through the front of the switch) or back-to-front airflow (air enters through the back of the switch).
Each power supply is cooled by its own internal cooling system. We ship QFX5120 switches with two AC or DC power supplies preinstalled in the rear panel of the chassis.

Pluggable Transceivers and Direct Attach Cables Supported on QFX5120 Switches QFX5120 switches support SFP, SFP+, SFP28, QSFP+, and QSFP28 transceivers. They also support direct attach cables. You can find the list of transceivers supported on QFX5120 switches and information about those transceivers at the following pages: •...
Cable Specifications for QSFP+ and QSFP28 Transceivers on QFX5120 Switches The 40GbE QSFP+ and 100GbE QSFP28 transceivers used in QFX5120 switches use 12-ribbon multimode fiber crossover cables with MPO/UP, MPO/UPC, or MPO/APC socket connectors. The fiber can be either OM3 or OM4. We do not sell these cables.
(Continued) Table 53: QSFP+ and QSFP28 MPO Fiber-Optic Crossover Cable Pinouts How to Calculate the Fiber-Optic Cable Power Budget for QFX Series Switches Calculate the fiber-optic data link's power budget when planning fiber-optic cable layout and distances to ensure that fiber-optic connections have sufficient power for correct operation. The power budget is the maximum amount of power the link can transmit.
1. Determine values for the link's minimum transmitter power (P ) and minimum receiver sensitivity ). For example, here, (P ) and (P ) are measured in decibels, and decibels are referenced to 1 milliwatt (dBm): = –15 dBm = –28 dBm NOTE: See the specifications for your transmitter and receiver to find the minimum transmitter power and minimum receiver sensitivity.

Prevention of Electrostatic Discharge Damage Device components that are shipped in antistatic bags are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets.
Figure 201: Placing a Component into an Antistatic Bag CAUTION: ANSI/TIA/EIA-568 cables such as Category 5e and Category 6 can get electrostatically charged. To dissipate this charge, always ground the cables to a suitable and safe earth ground before connecting them to the system. Attention Les câbles ANSI/TIA/EIA-568, par exemple Cat 5e et Cat 6, peuvent emmagasiner des charges électrostatiques.
• AC-powered devices are shipped with a three-wire electrical cord with a grounding-type plug that fits only a grounding-type power outlet. Do not circumvent this safety feature. Equipment grounding must comply with local and national electrical codes. • You must provide an external certified circuit breaker (2-pole circuit breaker or 4-pole circuit breaker based on your device) rated minimum 20 A in the building installation.
