Maintaining the ONS 15454 M12 (ANSI and ETSI),
ONS 15454 M2 and ONS 15454 M6 Shelf
This chapter explains how to maintain the ONS 15454 (ANSI and ETSI), ONS 15454 M2 and ONS 15454
M6 shelf installations.
Unless otherwise specified, “ONS 15454” refers to both ANSI and ETSI M12 shelf assemblies.
Note
Due to memory limitations, TCC2/TCC2P cards are not supported as the node controller in multi-shelf
configuration from R10.5.2.6. Hence, it is recommended to use TCC3 card as the node controller in multi-shelf
configuration. However, the TCC2/TCC2P cards can be used as a subtended controller and also in a stand-alone
configuration.

This procedure ensures that the air filter is free from dirt and dust, which allows
optimum air flow and prevents dirt and dust from entering the shelf.
