The host-model rule
A module number without its host is half a specification. Every module inquiry should name the host switch or router model and the slot it will occupy; the reply confirms fit before quoting. This one habit eliminates the most common module return: the right card for the wrong chassis generation.
Questions buyers ask
Can modules be ordered without the host switch?
Yes — spares and upgrades are common module orders; the host model is still required for the fit check.
Do uplink modules include their optics?
Optics are separate lines; state the link list and both are quoted together.
