Caution You must install the fan unit in a Release 1.0.1 shelf. Running the Release 1.0.1 shelf without the fan unit will result in a unit that is not compliant to any specifications, nor is warranted or supported by Cisco. In addition, such usage may result in equipment damage.

3.1.5 Fiber Organizer

The fiber organizer distributes the client fiber-optic cables to the ONS 15252 MCU CLIP modules. Additionally, the fiber organizer provides tension relief for the client fiber-optic cables. You can also install a fiber organizer between additional ONS 15252 MCUs or ONS 15201 SCUs located at a site. A fiber organizer is always included with an ONS 15252 MCU.

You can place the fiber organizer on the fan unit front. This placement does not interfere with fan unit filter replacement.

3.2 Physical Layout

This section describes the physical configuration of the ONS 15252 MCU and ONS 15201 SCU.

3.2.1 ONS 15252 MCU Physical Configuration

The ONS 15252 MCU physical configuration consists of a Network Control Board (NCB) module, Network Adaptation modules (NAMs), a Communication Interface module (CIM), Client Layer Interface Port (CLIP) modules, Hub Filter modules (HFMs), a pair of Line modules (LMs), and one Bridge module (BM) (see Figure 3-4). A pair of Termination modules (TMs) replace the BM when all optical signal channels or wavelengths are dropped at the ONS 15252 MCU. Additionally, when multiple ONS 15252 MCUs are interconnected, Connection Module X (CMX) and/or Connection Module Y (CMY) replace the BM. The type of connection module used depends on the specific ONS 15200 system configuration.
