- What is the difference between AFO and AFI on a QFX5100?
- Airflow direction. Air Out (AFO) draws air in at the port side and exhausts it past the power supplies and fans; Air In (AFI) runs the other way, from the power supply and fan side to the ports. Juniper notes that older switches called these front-to-back and back-to-front. Pick the direction that matches your hot and cold aisles; mixing directions in one chassis is not supported.

- Can QFX5100 switches be stacked or built into a fabric?
- Yes. Up to ten QFX5100 switches form a QFX Virtual Chassis managed as one device. A Virtual Chassis Fabric scales to 20 devices in a spine and leaf design, with up to four QFX5100 spines, and EX4300 switches can join as leaf devices.
- What condition and warranty come with a Juniper QFX5100 switch from Townsend?
- Each listing prints its own condition. Units sold as new, refurbished or used are bench tested before they are listed: every port and module slot is checked and the previous owner's configuration is erased. They are covered by the Townsend warranty from the date of delivery; if the hardware fails in normal use we repair it or replace it with a tested unit, and the length and terms are on our warranty page. Unused hardware can be returned within 30 days of delivery. Juniper software licences and support contracts are not part of our warranty.
