Not all Cisco PoE+ switches are able to power up the UHO-PoE-10 or VSP-UHO-PoE-10 outdoor housing (F.01U.300.502, F.01U.332.052).
Bosch has introduced the UHO-PoE-10 in 2014 following the IEEE802.3-2009 standards
Cisco claims that the Bosch UHO-PoE-10 at startup for a short moment (around 1 micro second) exceeds maximum current peek allowed by the updated IEEE 802.3-2015 standard, allowing the PSE (Power Source Equipment) to withdraw the power as a protective measure.
Due to analogue overcurrent protector components in the Cisco switch it can happen that tolerances may cause variety in behavior over different Cisco switches, even when the same model and setups are used.
Currently this behavior is only known on some Cisco models. (reports were seen on C2960X, C3560CX and recently C9200.)
