Cisco Board Pro 55 CS-BRD55P-K9= – Spare Service Unit, 55-Inch Board

Product Overview

CS-BRD55P-K9= is the service-unit part number for the Cisco Board Pro 55. The trailing equals sign marks it as a spare: it is bought to replace a board already in service, not to build a new room from scratch.

The hardware is the standard first-generation Board Pro 55 with the radio present and encryption enabled, which is what makes it a like-for-like swap for an installed CS-BRD55P-K9.

Board Pro 55 G1 reached end of sale on November 26, 2024 following the May 28, 2024 end-of-life announcement, with support running to November 30, 2029. That support window is exactly why sparing this platform still makes sense.

Estates that standardised on G1 keep one room build, one training document and one set of RoomOS behaviour by replacing failed units with the same part rather than mixing generations.

Product Description

A spare purchase is a different decision from a new-room purchase. What matters is that the replacement drops into the existing wall mount, uses the same cable set and presents the same interface to users on the morning after the swap, and a matching G1 board does all three.

Physically the unit is unchanged: 1228 x 69 x 700 mm, 40 kg board-only weight, lifting handles in the carton and a wall mount kit included unless a stand was ordered. If the failed board is on a wall stand or floor stand, that hardware stays on site and is reused.

The cable plant is reused as well. One 10/100/1000 LAN port, one 802.3af PoE port with a 15.4 W budget for the Cisco Room Navigator, one Ethernet port for external camera control and one audio-over-IP port for up to three Cisco Table Microphone Pro units. Local input remains USB-C DisplayPort Alternate Mode at 4Kp60 and HDMI 2.0 type A at 4Kp30, with one HDMI 2.0 type A output at 4Kp60.

Re-registration follows whatever the room already uses. Cisco documents Webex cloud activation, native on-premises registration to Unified Communications Manager or Expressway from 10.5.2 with the device pack, third-party H.323 gatekeepers and SIP proxies, and Microsoft Teams Rooms on Android, with a minimum of RoomOS 10.11.

Organisations that keep a spare on the shelf usually hold one unit per size per site. If the fleet is mixed, it is worth checking whether the newer generations in interactive displays should be the spare instead, and whether the failed room is a candidate for a full rebuild from meeting room bundles.

Replacement mounting hardware, where the original bracket was damaged during removal, is listed separately in display mounts.

Key Features

• Service-unit part number — The equals-sign SKU is Cisco's spare designation, intended for replacement of a deployed board rather than a first-time room build.
• Identical to the deployed G1 hardware — Users see the same 55-inch 4K panel, the same dual 4K 12 MP cameras and the same RoomOS behaviour after the swap.
• Reuses the existing mount and cabling — The board mounts and cables the same way, so a break/fix visit does not become a re-cabling project.
• Supported to November 30, 2029 — Cisco's published last date of support for Board Pro 55 G1 sets the horizon for how long sparing this platform is worth doing.
• Encryption-enabled build — The K9 designation is Cisco's encryption-enabled variant, matching the security posture of the unit being replaced.
• Room Navigator support unchanged — The 802.3af PoE port with a 15.4 W budget continues to power and pair the existing touch controller.

Typical Applications

• Conference room — A failed board in a standardised small or medium conference room is returned to service with the same hardware.
• Training room — Rooms in daily teaching use benefit most from an on-site spare, because the replacement window is measured in hours.
• Commercial meeting space — Multi-site estates hold service units centrally and ship them to whichever building has the fault.
• Government space — Where a room build is documented and accredited, replacing like for like avoids re-approving a different model.

Frequently Asked Questions

What does the equals sign mean on this part number?

Cisco uses the trailing equals sign to designate a spare or service unit. It is the same hardware, ordered for replacement of an existing deployment rather than as a new system.

Will it fit the mount already on the wall?

It is the same Board Pro 55 chassis, so the existing wall mount kit, wall stand or floor stand is reused. Cisco publishes a board-only weight of 40 kg for the G1 and G2 generations.

How long will Cisco support this platform?

Cisco set the last date of support for Board Pro 55 G1 at November 30, 2029, following end of sale on November 26, 2024.

Does a spare need a different software load?

No. The minimum software for the G1 Board Pro is RoomOS 10.11 or later, and the unit picks up the room's configuration once it is registered.

Can this unit be registered on-premises?

Yes. Cisco documents native registration to Cisco Unified Communications Manager or Cisco Expressway from version 10.5.2 or later with the device pack, alongside Webex cloud activation.

Should we spare G1 or move to a current generation?

If the room is documented and the fleet is standardised, a matching G1 spare is the lower-risk choice within the support window. If the room is due for refresh anyway, the current Board Pro generations are the better spend.

What warranty applies to a service unit?

Cisco publishes a 90-day limited liability warranty for this product class. Warranty is handled per Cisco's standard terms; contact Creation Networks to confirm coverage for your order.
