Ports 0, 1, 2, and 3 are 2.5G/1G copper. · Service port: 1x GE port. · High Availability (HA) port: 1x GE port.

Data port behavior: · If the 10G/Multigigabit copper port (or 10G/1G fiber port) is enabled, the 4x 2.5G/1G ports will be
automatically disabled. · The 10G/Multigigabit copper port (or 10G/1G fiber port) will be disabled if link aggregation (LAG) is
enabled only 4x 2.5G/1G ports can be used for link aggregation.
With this form factor, two controllers can be placed in the same rack to conserve rack space, as shown in Figure 3.

Rear panel view The rear of the chassis supports: 1. 6-pin power connector for an external 12VDC/110W power adapter (C9800-AC-PWR) 2. Kensington lock feature Figure 6 shows the rear of the 9800-L controller.
Figure 5. Rear panel view

Fans An internal blower provides forced-air cooling. Fan control is based on a simple linear, closedloop, continuously variable voltage circuit that monitors the CPU temperature and external heatsink temperature. Built-in temperature hysteresis eliminates needless fan cycling.
Airflow is from front I/O side to the rear of the chassis. Do not block or obstruct airflow.

High availability with SSO

The 9800-L supports full access point and client Stateful Switchover (SSO). Client SSO is supported for clients that have already completed the authentication and Dynamic Host Configuration Protocol (DHCP) phase and have started passing traffic. With client SSO, a client's information is synced to the standby wireless controller when the client associates to the wireless controller or the client's parameters change. Fully authenticated clients--the ones in the run state--are synced to the standby, thus avoiding client re-association on switchover and making the failover seamless for the APs as well as for the clients. This process results in zero client service downtime and zero SSID outage. The overall goal for the addition of AP and client SSO support to the Cisco Catalyst 9800-L Wireless Controller is to reduce major downtime in wireless networks due to failure conditions that may occur due to box failover, network failover, or a power outage at the primary site.
