I suspect that is a crate we got for free from APS when they were upgrading. It is the less expensive version without the switches that allow missing modules.
FWIW
These simpler crates often have backplane jumpers that you can add to close the daisy-chains for each slot that isn't occupied.

The jumpers must be present for each free slot and must not be present for each used slot - pretty inconvenient and error-prone.
