C9800-40-K9 Cisco’ Catalyst 9800-40 Wireless Controller.

The purpose of this document is to provide an overview of the Cisco Catalyst 9800-40 and 9800-80 Wireless Controller Series, and their deployment within the Cisco Digital Network Architecture.

There are no specific requirements for this document.

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

The explosion of mobile clients in enterprise empowered by bring your own device (BYOD), the deployment of wireless in mission-critical applications, and the adoption of Wi-Fi in service provider networks enabling new business models require wireless networks to provide larger AP Scale, client scale and higher throughput.

The new Cisco Catalyst 9800 Wireless Controllers provide support for 40 and 80 Gbps throughput with support for 2000 APs, 32000 clients and 6000 APs and 64000 clients respectively to ensure better performance and scale for business-critical networks.

The table below captures some of the key hardware capabilities of this new platforms.

The Cisco Catalyst 9800 Wireless Controller C9800-40-K9 and C9800-80-K9 supports the following 11ax, 11ac Wave 1 and Wave 2 Access Point models:

• 9115AX, 9117AX, 9120AX (AP Device pack in release 16.11)
• AP18xx, 2802, 3802, 1540, 1560
• 1700, 2700, 3700, 1570

Cisco Catalyst 9800 Wireless Controllers support all the features of Cisco Catalyst Wireless software release 16.10.

Cisco C9800-40-K9 Wireless Controller supports several LED indicators, and external interfaces on the front panel.

Figure 1. Cisco C9800-40-K9 Wireless Controller Front View

By default, the interfaces from 0 - 3 in the Cisco C9800-40-K9 Wireless Controller are enabled.

If both the Redundancy Ports are connected.

SFP Gigabit Ethernet port takes precedence if they are connected at same time.

There is no change if SFP port is connected after HA is up over RJ-45 port.

HA between these two links is not supported.

Only Cisco supported SFPs (GLC-LH-SMD and GLC-SX-MM‘D) are supported for RP port.

When HA link is up via RJ-45, SFPs on HA port should not be inserted even if there is no link between them. As it is a physical level detection, this would cause the HA to go down as precedence is given to SFP.

The following figure shows the port numbering for the built-in ports.

The port LEDs behave as follows:

Off—Indicates the port is not enabled by software.

Amber—Indicates the port is enabled by software but there is a problem with the link.

Green—Indicates the port is enabled by software and there is valid link.

Network ports for this controller support the following Cisco SFP/SFP+ modules:

GLC-BX-D

GLC-BX-U

GLC-LH-SMD

GLC-SX-MM‘D

GLC-ZX-SMD

The chassis has a front-to-rear airflow. Six internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. The fans are numbered from 0 to 5, right to left. The system is designed to operate indefinitely even if one of the fans fail. To reduce noise and power and increase fan lifetime, the speed of fans is automatically adjusted based on chassis inlet temperature. In the event of a single fan failure, all remaining fans will be increased to 100% fan speed account for the failed fan. However, multiple fan failures may result in over temperature and shut down.

Two power supplies (AC) are accessed from the rear of the controller and are hot-swappable. The Cisco C9800-40-K9 Wireless Controller supports AC power supply. The modular chassis configurations support the installation of two power supplies for redundancy. When an external power supply fails or is removed, the other power supply provides power requirements for the chassis. This allows you to hot-swap the power supply without impacting the functionality of the controller.

The following table describes the power supply LEDs.

Cisco C9800-40-K9 Wireless Controller shall have a minimal amount of separate orderable items, including all of the following:

AC Power Supplies

Rack mount bracket kit

The Cisco C9800-80-K9 Wireless Controller is a 100G wireless controller that occupies two rack unit space and supports a pluggable Module slot, and eight built-in 10GE/1GE interfaces.

Cisco C9800-80-K9 Wireless Controller supports several LED indicators, and ports on the front panel. The front panel includes the following ports and LEDs.

The port Link and Status LEDs behave as follows:

C9800-18X1GE

Eighteen 1GE-ports that support small form-factor pluggable (SFP) optical transceivers to provide network connectivity. Ports are numbered 0 – 17

C9800-10X10GE

Ten 10GE-ports that support small form-factor pluggable (SFP+) optical transceivers to provide network connectivity. Ports are numbered 0 – 9.

C9800-2X40GE
