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 switches in a single logical switch.

The Catalyst 9400 Series chassis is enterprise optimized with efficient side-to-side airflow and full front accessibility for all removable components, including supervisors, line cards, power supplies and fan tray. The chassis also supports optional rear accessibility for fan trays to enable efficient cable management. Catalyst 9400 Series chassis, supervisor, line cards, powersupply and fan trays have embedded RFID tags which facilitate easy asset and inventory management using commercial RFID readers.

Supervisor configuration

The Catalyst 9400 Series offers an industry-leading supervisor engine built for secure networks, IoT applications, next generation mobility and cloud adoption. Supervisor Engine-1 options (Sup-1, Sup-1XL, Sup-1XL-Y) are built with the latest Unified Access Dataplane 2.0 (UADP2.0) ASIC future-proofed for next generation technologies with its programmable pipeline, microengine capabilities and template-based configurable allocation of Layer 2, Layer 3, forwarding, Access Control Lists (ACLs) and QoS entries.

Line card configuration options

The Catalyst 9400 offers the ability to mix and match a range of line cards to support numerous LAN access, server connectivity, Small and Medium-sized Business (SMB) or branch-office deployments. The Cisco Catalyst 9400 Series supports the line cards listed in Table 4 by part number.

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 failure of one (+1) of the circuits as opposed to power supply unit failure.

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.             Cisco Catalyst 9400 Series Power supply specifications

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.

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 cable management. The chassis is enterprise closet-optimized with side-to-side airflow. All fan trays are composed of multiple independently controlled fans with N+1 redundancy. If any single fan fails, the system will continue to operate without a degradation in cooling. Speeds of fans change dynamically to compensate for fan failure. 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.
