Want to summarize with AI?

Explains configuration procedures for Cisco Catalyst Pluggable Interface Modules, including operational adjustments, best practices, antenna attachment for reliable connectivity, and RF band mapping for P-5GS6-GL modules to ensure proper hardware integration and performance.

To insert the antenna in the Pluggable Interface Module, perform the below steps:

Procedure

	1.	Use your thumb and index finger to insert and tighten antenna 1 and antenna 3 in the middle antenna attachment slots as indicated in the figure. Note While installing the antennas, first install antenna 1 and antenna 3 (this instruction is for the two antenna attachments present in the middle) and secure it completely. If you install antenna 2 and antenna 0 first (this refers to the first and the last antenna attachments), there will be less space to insert your thumb and index finger and therefore you may not be able to secure antenna 1 and 3.
	2.	Insert antenna 2 and antenna 0 in the first and last antenna attachment slots.
	3.	After installing the antennas, adjust the antenna orientation by spacing out each of them equally until they are spread out. This is important as it helps in getting higher RF performance.

Attaching the antennas

To attach the antenna in the Pluggable Interface Module, perform the below steps:

Note

5G NR Antenna (5G-ANTM-04-B) is supported on both P-LTEAP18-GL and P-5GS6-GL PIMs.

Attach each SMA cable to the ports as indicated in the table mappings.
Ensure that you tighten and secure each SMA cable into the SMA connector on the PIM.

5G-ANTM-O-4-B	P-LTEAP18-GL	P-5GS6-GL
MAIN 0 (LTE1)	Main 0	ANT 0
MAIN 1 (LTE3)	Main 1	ANT 1
DIV 0 (LTE2)	DIV 0	ANT 2
DIV 1 (LTE4)	DIV 1	ANT 3
GNSS	No connection	GPS
