Chapter 9 Node Reference
9.2 Multishelf Node
Note The reason for extending the number of subtending shelves from eight to 12 is to accommodate and
manage the new optical and DWDM cards that operate in the even band frequency grid.
The node controller is the main shelf; its TCC2/TCC2P cards run multishelf functions. Each subtending
shelf must be equipped with TCC2/TCC2P cards, which run the shelf functions. For internal data
exchange between the node controller shelf and subtending shelves, the node controller shelf must be
equipped with redundant MS-ISC-100T cards or, as an alternative, the Catalyst 2950 switch. Cisco
recommends using the MS-ISC-100T cards. If using the Catalyst 2950, it is installed on one of
multishelf racks. All subtending shelves must be located in the same site at a maximum distance of 100
meters or 328 feet from the Ethernet switches used to support the communication LAN. Figure 9-19
shows an example of a multishelf node configuration.
