PoE doesn't seem to be enabled on the camera switch at the server room and I couldn't enable it because IP address of this switch is missing.
So I moved a2A5328-4gmPRO near the camera switch at the IOO0 rack on which PoE is enabled and a2A5328-4gmPRO came back online again (Fig.1).
But, I found that the switch at IOO0 rack and one at server room were only linked at 1G, contrary to what I had been told.
For this reason, I haven't yet done the test with the network which should have sufficient capability.
Anyway, both a2A5328-4gmPRO and acA4112-8gm are now online.

In today's work, I understood the camera network configuration is completely chaos. IP address information on JGW wiki was not true for 3 of 6 network switches. I tried to do ping-search beyond L3 segment by using virtual NIC but 2 of 6 switches including the core switch at the server room are still missing. 2 of found 4 switches don't have a reachable route because the inconsistency between the physical and logical connections. A drastic reassessment is required.

As mentioned above, the link speed between the IOO0 and the server room is 1G though it should be 10G. According to my check, I couldn't find any reason why the link speed between IOO0 and the server room is limited as 1G on the switch at the IOO0 rack. So I'm doubting it comes from the settings on the core switch at the server room. But the core switch is still missing. So we need salvage it at first. Or using USB-RJ45 console cable if someone have...
