MULTISHELF CABLE CONNECTIONS

Note: Multishelf networks cannot be connected through a router because the local shelf uses UDP- broadcast messages as a mechanism to automatically discover other shelves in the network, and routers generally filter these broadcasts. A multishelf network is limited to 32 shelves.

To connect the shelves using the 10BASE-T Ethernet connectors (Figure 2-4):

Step

Action

1Plug an RJ-45 cable into the 10BASE-T connector at the rear of each shelf.

2Plug the other end of the RJ-45 cables into the hub/switch connecting the shelves.

Note: The length of each RJ-45 cable cannot exceed 100 meters (328 feet).
