You can insert these hands symbols on your Windows and Mac documents using alt code shortcuts. Emoji hand symbols are solid and colorful while normal symbols are like line diagram glyphs. Unicode has two types of hands symbols emoji and normal code points. For this reason, upgrading the EPLD/FPGA software of the switch is a good step to take when troubleshooting odd optic/transceiver issues like this. It is very common to use hands symbol on chat conversations for OK, thumbs up, etc. The MI FPGA in Nexus 9000 series switches interacts with transceivers over I2C buses (among other things) and can contribute to issues like this, where detecting an inserted transceiver or reading the SPROM of a transceiver returns unexpected results.

You can find more information about the process for this in the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes, Release 9.3(7) document. If possible, upgrade the EPLD/FPGA software of the switch to match the upgraded NX-OS software of 9.3(7).If possible, upgrade the NX-OS software of the switch to the current recommended NX-OS software release, which is 9.3(7) or 9.3(7a) at the time of this writing.This doesn't necessarily mean that third-party optics, transceivers, or cables won't work in Cisco network devices it just means that when you face issues similar to this that involve a third-party hardware component, eliminating that third-party hardware component as a potential factor is the first step of troubleshooting. This means that Cisco does not test their network devices with any third-party optics, transceivers, or cables, and thus Cisco cannot qualify or guarantee the behavior of a network device when using a third-party optic, transceiver, or cable. Per the Cisco Optics-to-Device Compatibility Matrix, Cisco does not support third-party optics, transceivers, or cables.
