Redundant GCMs can be different types; e.g., a GCM with integrated optics (OC-12/STM-4 and OC-48/STM-16) placed with an Enhanced GCM for GCM redundancy.

While the VTX can be in a 1:1 or unprotected group, the related OC-N/STM-N facilities can be unprotected or in a 1+1 APS/MSP, UPSR/SNCP, or BLSR/MS-SPRing protection group.
Important:
For electrical port usage only, place an OC-N/STM-N or 1-slot blank faceplate between any 10/100BaseTX-inclusive
card and an electrical card (of another type), if the 10/100BaseTX-inclusive card is placed to the right of an electrical interface card.
A blank faceplate or OC-N/STM-N card is not required if the 10/100BaseTX-inclusive card is placed to the left of an electrical card.
If the 10/100BaseTX-inclusive card also contains optical ports, and if the user intends to ONLY use the optical ports, this electrical
port usage restriction does not apply.
Important:
Place 1-slot wide blank faceplates in empty slots to ensure EMI protection and proper cooling.
