Advanced persistent security threats, exponential growth of Internet of Things (IoT) devices, mobility everywhere and cloud adoption require a network fabric that integrates advanced hardware and software innovations to automate, secure, and simplify customer networks. The goal of this network fabric is to enable customer revenue growth by accelerating business service rollout. The Cisco® Digital Network Architecture (Cisco DNA) with Software-Defined Access (SD-Access) is the network fabric that powers business. Cisco DNA is an open and extensible, software-driven architecture that...

Cisco DNA for Access lets you manage your entire switching structure as a single, converged component. With one management system and one policy for wired and wireless networks, it offers an efficient way to provide more secure access. Figure 1. Cisco Catalyst 9400 Series Cisco Catalyst 9400 Series chassis The Cisco Catalyst 9400 Series offers three chassis options and a wide range of line card options (Table 1). It provides a common architecture that can scale up to 400 ports. Cisco StackWise Virtual technology doubles this port density by virtually stacking two Catalyst 9400 modular...

Table 3 lists the minimum software requirements for the Cisco Catalyst 9400 supervisor engine. Table 3. Cisco catalyst Supervisor Engine Software Minimum Requirements The Cisco Catalyst 9400 Series has flexible interface types and port densities that allow you to mix and match network configurations to meet the specific needs of campus networks (Table 5). © 2019 Cisco and/or its affiliates.

Cisco Catalyst 9400 Series Maximum port densities Power supply There are three modes of operation supported by Cisco Catalyst 9400 power supplies. In all the modes the power supplies can be of different wattage and type whether AC or DC. Redundant N + N mode The Cisco Catalyst 9400 Chassis also supports N + N redundancy with N independent input circuits and safeguards against failure of N (+N) of the circuits as opposed to power supply unit failure. Redundant N + 1 mode The Cisco Catalyst 9400 Chassis also supports N + 1 redundancy with N independent input circuits and safeguards against...

Combined mode In this mode the power available for the entire chassis is equal to the sum of the output power of both of the power supplies multiplied by the share ratio. P = Power output of one power-supply unit. Total combined mode power = P + (N-1) P (share ratio). Tables 7 describe power supply specification for the Catalyst 9400 Series. Table 7.

Note: • Output power is per power supply unless otherwise stated. • Heat-dissipation numbers represent the power conversion losses of the power supply in operation. • The number of power devices supported depends upon the customer configuration. Power supply indicators • Output Fail LED (per unit): RED. • Input Okay LED (per unit): Green. • ID LED (per unit): Blue. Table 8. Cisco Catalyst 9400 Series power-cord options Fan trays Each Cisco Catalyst 9400 Series uses dual serviceable fan trays for cooling. Cisco Catalyst 9400 switches can optionally be accessed from the rear for flexible...

Catalyst 9400 Series fans have a barometric sensor, which allows slower fan speed curves at lower altitudes. Catalyst 9400 Series fans also have individual fan Pulse-Wide Modulation (PWM) fine-tuning to reduce variability in fan Revolutions Per Minute (RPM) under throttled conditions. This allows for optimal acoustic performance at 60dB when the system is operating at 50% load. Figure 2. Dual serviceable fan tray Environmental conditions The Cisco Catalyst 9400 Series require the following conditions: ● Operating temperature Normal operating* temperature and altitudes: ◦ 23° to 113°F (-5 to...
