Cisco DP-9800-KEM-WMK Wall Mount Kit for 9800 Key Expansion Module | 9841 9851 9861 9871 | New

The Cisco DP-9800-KEM-WMK is the official OEM Wall Mount Kit for the Cisco Desk Phone 9800 Series Key Expansion Module (KEM), purpose-built to enable secure vertical wall installation of a Cisco 9800 Series IP Phone with an attached DP-9800-KEM module. Compatible with Cisco Desk Phone models 9841, 9851, 9861, and 9871, this kit accommodates the combined width and weight of a KEM-equipped phone assembly — something the standard phone WMK alone cannot support. Mounts on drywall, concrete, and brick surfaces. All installation hardware is included: one wall bracket, one phone bracket, four M4 L25 screws, four drywall anchors, three M3 L7 screws, and one WMK key — no separate hardware purchase required. Important: wall-mounting a KEM-equipped 9800 Series phone requires both this kit (DP-9800-KEM-WMK) and the standard phone wall mount kit (DP-9800-WMK=), sold separately.

Cisco DP-9800-KEM-WMK - Key Features & Benefits

• KEM Wall Mount — Designed for KEM-Equipped Phones: Engineered specifically to support the added width of a Cisco DP-9800-KEM Key Expansion Module attached to a 9800 Series phone. The standard DP-9800-WMK= alone is not sufficient for KEM configurations — this kit provides the KEM-side bracket required for a complete installation
• Compatible with Cisco Desk Phone 9841, 9851, 9861, and 9871: Officially supports all four KEM-capable models in the Cisco 9800 Series. Use with the DP-9800-KEM module for up to 3 KEMs on 9861 and 9871, or 1 KEM on the 9851
• Complete Hardware Package — Nothing Else to Buy: Includes all mounting hardware: 1× wall bracket, 1× phone bracket, 4× M4 L25 screws, 4× drywall anchors, 3× M3 L7 screws, and 1× WMK key. Supports installation on drywall, concrete, and brick surfaces
• Frees Up Desk and Counter Space: Vertical wall mounting eliminates the phone’s footprint entirely, making it ideal for reception counters, hallways, shared workstations, stockrooms, and any high-traffic environment where horizontal surface space is at a premium
• Genuine Cisco OEM Accessory: Designed and manufactured by Cisco to precise mechanical tolerances for the 9800 Series platform. Ensures proper fit, cable routing clearances, and structural stability over the life of the deployment

Cisco DP-9800-KEM-WMK - Frequently Asked Questions (FAQ)

• Do I need anything else besides this kit to wall-mount my phone?
  Yes — mounting a KEM-equipped Cisco 9800 Series phone requires both this kit (DP-9800-KEM-WMK) and the standard phone wall mount kit (DP-9800-WMK=, sold separately). This listing is for the KEM bracket only.
• Which Cisco 9800 phones is this compatible with?
  This kit is compatible with the Cisco Desk Phone 9841, 9851, 9861, and 9871 when paired with the DP-9800-KEM Key Expansion Module. It is not compatible with the 9811 as the 9811 does not support the KEM.
• What surfaces can I mount this on?
  The kit supports installation on drywall, concrete, and brick. Drywall anchors are included for standard interior wall installations. For concrete and masonry, use the provided M4 L25 screws.
• Is this compatible with the older Cisco 8800 Series wall mount bracket?
  No. This kit is designed for the 9800 Series mounting system. For users upgrading from the 8800 Series, Cisco offers a separate adapter (DP-9800-WMK-88ADP=) to use 8800 Series brackets with 9800 Series phones — that adapter does not apply to KEM configurations.
• How many KEMs can I attach to my 9800 Series phone?
  The 9851 supports up to 1 KEM; the 9861 and 9871 support up to 3 KEMs. Each additional KEM beyond the first requires an external Cisco Power Adapter 3. This wall mount kit covers a single KEM attachment.
