CW9800H2 Description
The CW9800H2 is a Cisco Catalyst CW9800 Series 1RU wireless controller appliance that anchors campus and multi-building WLANs of Wi-Fi 5 Wave 2, Wi-Fi 6/6E and Wi-Fi 7 access points. The appliance supports up to 6,000 access points, 64,000 clients and 100 Gbps of throughput through 8x 1/10G SFP+ ports and 2x 40G QSFP+ ports, and runs on one of its two hot-swappable power modules at a 500W maximum. The 40G ports accept only the QSFP+ optics and cables on the supported list.

Application Scenarios
Across office towers, teaching buildings and dormitories, the controller terminates wireless traffic from up to 6,000 access points over 40G links toward the core.
A headquarters or hub site holds configuration, policy and RF management for branches running FlexConnect, where remote access points switch traffic locally.
In a policy-driven SD-Access campus, the controller serves as the wireless control plane and brings Wi-Fi 6E and Wi-Fi 7 access points into the fabric next to wired access.

CW9800H2 and CW9800H1 match on 6,000 APs, 64,000 clients, 100 Gbps and the PWR-CH1-750ACR AC spare, and the one hardware difference is the uplink: CW9800H2 has 2x 40G QSFP+ where CW9800H1 has 4x 25G SFP28, so a core that terminates 40G links takes CW9800H2 and an aggregation layer on 25G optics such as SFP-25G-SR-S takes CW9800H1. Designs above 3,000 APs, 32,000 clients or 50 Gbps need one of these two, because CW9800M tops out at those figures. CW9800M also takes a different AC spare, PWR-CH1-750WACR, so one spare PID does not cover a mixed estate.
Ordering Checklist
- Power module feed: Choose AC or DC modules at order time; spares are PWR-CH1-750ACR (750W AC) or PWR-CH1-950WDCR (950W DC). Both modules ship pre-installed, so the wrong feed type means a rebuild.
- AP subscription: Add one LIC-CW-E (Essentials) or LIC-CW-A (Advantage) entitlement for each AP; unified SKUs need IOS XE 17.15.x or later, otherwise per-AP Cisco DNA subscriptions. The controller starts without a license, but each AP that joins needs its own subscription.
- 40G QSFP+ optics: Add optics or cables for the 2x 40G ports, for example QSFP-40G-SR4, QSFP-40G-LR4, QSFP-H40G-CU or QSFP-H40G-AOC. The QSFP+ ports accept only items on the CW9800H2 supported list.
- 1/10G copper SFP: SFP-10G-T-X needs IOS XE 17.18.3 or later; other 1/10G optics such as SFP-10G-SR or GLC-TE are listed without that condition. A copper SFP+ ordered for an earlier release does not come up.
- Rear rack kit: Add C8500-4PT-KIT= as the rear rack-mount kit for the CW9800 chassis; it is a separate part number and is not part of the controller order.
