Chapter 1 Installation
Connecting to the ONS 15200 System
1.3.1 Connection Restrictions
Restrictions determine which network elements (NEs) can be accessed based on the unit where the
Maintenance Manager is physically connected. If the Maintenance Manager is connected to an SCU, you
can only view information for the CLIP module installed in that SCU and its mate, which is assigned the
same ITU channel, in another SCU or MCU. All other channels in the network are invisible. If the
Maintenance Manager is connected to an MCU, you can see all the CLIP modules installed in that MCU
as well as the mates of that MCU’s CLIP modules.
Note If you connect the Maintenance Manager directly to an MCU, only that Maintenance Manager will
receive alarm notifications from the CLIP modules in view, even if other MCUs or SCUs were
connected prior to the latest MCU’s connection. Before connecting the Maintenance Manager to an
MCU, you should make sure no one is already accessing Maintenance Manager through another
MCU or SCU in the network.
Procedure: Connect the Laptop to an MCU
The following procedure describes how to connect a laptop with Maintenance Manager to the
ONS 15252 MCU. To connect to a desktop computer, contact the Cisco Technical Assistance Center
(TAC) at 1-877-323-7368.
Step 1 Insert the CAN board into an empty PCMCIA slot on the laptop computer.
If this is the first time the CAN board is being installed in the computer, the hardware driver must be
installed. To install the hardware driver, read the installation instructions included on the Maintenance
Manager CD-ROM.
Step 2 Attach the RJ-45 connector at the end of the CCAN LINE connector cable to the Maintenance Access
(MA) port on the Communications Interface module (CIM) (Figure 1-6). The CIM is located below the
Network Control Board (NCB) module in Slot 17 on the right side of the MCU. The MA connection on
the CIM module is a standard RJ-45 connector.
