Cisco Board Pro 55 CS-BRD55P-NR-K9= – No-Radio Spare Service Unit

Product Overview

In an accredited room, the replacement board has to be as radio-free as the one it is replacing. CS-BRD55P-NR-K9= is the spare service unit for exactly that situation: the no-radio Board Pro 55, ordered against an existing deployment.

Swapping a no-radio board for a standard one is not a like-for-like repair in a secure facility, because it reintroduces a wireless emitter into a space that was signed off without one.

This part number combines both markers: NR for the build with Wi-Fi and Bluetooth removed, and the trailing equals sign for spare or service unit only.

Board Pro 55 G1 went end of sale on November 26, 2024 after the May 28, 2024 announcement, with a last date of support of November 30, 2029, so a no-radio estate on this platform has a defined sparing window.

Product Description

The value of holding this SKU is time. Sourcing a no-radio variant after a failure is slower than sourcing a standard one, and in a facility with a controlled room list the alternative is leaving the space out of service until the correct build arrives.

Nothing about the swap changes the room's cabling. The board joins the network on its 10/100/1000 RJ-45 LAN port, powers and pairs the existing Cisco Room Navigator from the 802.3af PoE port with its 15.4 W budget, and keeps the separate Ethernet ports for external camera control and audio over IP, which carries up to three Cisco Table Microphone Pro units.

Local connectivity is also unchanged: USB-C DisplayPort Alternate Mode at 4Kp60, an HDCP-compatible HDMI 2.0 type A input at 4Kp30 and one HDMI 2.0 type A output at 4Kp60, plus two analog microphone inputs and a 3.5 mm stereo line out.

For a closed network, the on-premises path matters more than the cloud one. Cisco documents native registration to Cisco Unified Communications Manager or Cisco Expressway from version 10.5.2 with the device pack, along with third-party H.323 gatekeepers and standards-based SIP proxies. Documented network security includes 802.1X with passphrase or X.509 client certificate, 802.1Q VLAN, 802.1p QoS and SRTP using AES-128-GCM or AES-256-GCM.

Estates that run mixed secure and open rooms often hold one no-radio spare and one standard spare per site. Current-generation alternatives, if the room is due for rebuild rather than repair, are listed in interactive displays and video conference systems.

Key Features

• No-Radio spare designation — The NR build with the equals-sign spare marker is the only correct replacement for a deployed no-radio board in an accredited room.
• Wi-Fi and Bluetooth absent — Cisco lists Wi-Fi as not available in non-radio versions, so the room's wireless-free status is preserved through the repair.
• Wired network attachment — A single 10/100/1000 Ethernet LAN port carries the endpoint, with 802.1X authentication using a passphrase or an X.509 client certificate.
• Existing control surface reused — The 802.3af PoE port with a 15.4 W budget re-powers the Room Navigator already installed at the table.
• Media encryption unchanged — SRTP with AES-128-GCM or AES-256-GCM and H.235 v3 with AES-128 or AES-256 match the security posture the room was approved against.
• Defined support horizon — Cisco's last date of support for Board Pro 55 G1 is November 30, 2029, which bounds how long the no-radio estate should be spared.

Typical Applications

• Government space — Rooms on a controlled list are returned to service without a change to the approved equipment build.
• Conference room — A wireless-free conference room in a regulated business keeps its configuration through a board replacement.
• Commercial meeting space — Organisations with RF policies in specific buildings hold this spare alongside the standard unit.
• Multi-purpose room — Spaces that host both routine and sensitive sessions stay usable for the stricter of the two.

Technical Specifications

Frequently Asked Questions

Can a standard K9 board be used to replace a no-radio unit?

Not in a facility that excluded wireless emitters from the room approval. The standard build includes Wi-Fi and Bluetooth, which changes what was signed off. The NR spare keeps the room as documented.

What is physically different about the no-radio build?

Cisco lists Wi-Fi 802.11a/b/g/n/ac (2.4 and 5 GHz) as not available in non-radio versions on this generation. The device is attached over wired Ethernet.

Does the spare come with a mount?

A wall mount kit ships by default and is omitted when a floor stand or wall stand is selected. On a repair the existing mount is normally reused.

How is the board authenticated onto a secure network?

Cisco documents 802.1X network authentication using either a passphrase or an X.509 client certificate, with 802.1Q VLAN and 802.1p QoS/CoS support.

Which on-premises call control does it support?

Native registration to Cisco Unified Communications Manager or Cisco Expressway from version 10.5.2 or later with the device pack, plus third-party H.323 gatekeepers and standards-based SIP proxies.

What warranty applies?

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.
