Cisco Wi-Fi Interface Module (WIM)

This chapter contains the following sections:

Overview

This section provides an overview of the Cisco Wi-Fi Interface Module (WIM). The PID is WP-WIFI6-x where x signifies the regulatory domain.

Highlights of the WIM are:

  • Pluggable 802.11ax module for Cisco Catalyst IR1800 series

  • WiFi-6 (802.11ax), 2x2 MIMO with 2 spatial streams

  • Extended Temperature Range

  • Field Replaceable Unit (FRU), however does not support OIR (Online Insertion and Removal)

  • Versatile RF coverage with external RP-SMA antenna connectors

  • Flexible Antenna Port feature support

  • Based on the Cisco AP 9105AXI

The following graphic shows the front panel of the WIM.

Installation

The Cisco Wi-Fi Interface Module remove and replace options are shown in the following steps.

The Router may have a blank plate covering the Wi-Fi Interface Module slot. This will need to be removed prior to installing the Wi-Fi Interface Module. The following example shows the Wi-Fi Interface Module.

Procedure

Step 1

Remove the blank plate by unscrewing the latch lock screw(1 ) that holds the plate secure. Refer to the following graphic.

Figure 1. Latch Lock Screw

Step 2

Slide the blank plate out of the device.

Step 3

Slide the Wi-Fi Module into the device as shown in the following graphic. The latch lock screw (1 ) aligns with the screw hole (2 ) on the face of the device. Push the Wi-Fi Module all the way into the device until you feel it seat, and then torque the latch lock screw 8-10 inch-pound (0.9 to 1.1 newton meter).

Figure 2. Wi-Fi Module Insert

Step 4

Attach your antennas to the ports on the Wi-Fi module. There are different instructions for each antenna type, be sure to consult the antenna documentation for proper orientation and torque to install them.

Step 5

If no antennas are being installed on a port, make sure the caps are installed on the connector.

Thermal Mitigation

The following table provides a description of thermal mitigation levels and throughput performance.

This applies to the IR1835 with dual P-LTEAP18-GL pluggable modules and the WP-WIFI6 pluggable module.

The WP-WIFI6 pluggable will experience normal operation up to 55°C /131°F. Under normal conditions both 2.4 and 5 GHz radios of the WP-WIFI6 pluggable operate in 2x2 MIMO mode, with antenna ports A and B active. Upon exceeding the ambient temperature and airflow levels indicated in the thermal mitigation table, both 2.4 and 5 GHz radios may throttle to 1x1 SISO. In 1x1 SISO mode only antenna port A is active, and each radio is restricted to single spatial stream data rates.
