Accton Technology 12i, 12mi SNMP manual Connecting to the Stack’s Backplane

Fast EtherHub 3500 System User’s Guide

2.Connect one end of the cable to the RJ-45 port of the network interface card, and the other end to any available (MDI-X) station port on the hub. Just remember that if you use Port 12MDI-X, the daisy-chain port (12MDI) cannot be used. When inserting an RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. Using the hub in a stand-alone configuration, you can network up to 12 nodes.

ΙDo not plug a phone jack connector into the RJ-45 port. This may damage the switch. Instead, use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.

Notes: 1. Make sure each twisted-pair cable does not exceed 100 meters.

2.We advise using Category 5 cable for all network connections to avoid any confusion or inconvenience in the future when you upgrade attached devices to Fast Ethernet.

3.You may also connect a device to the switching port located on hub’s front panel if required. However, be sure you use a SmartExtender Module that meets your communication requirements. Refer to SmartExtender Module in Chapter 1 for more details.

4.To facilitate troubleshooting, label all network cables to indicate the attached device and location.

Connecting to the Stack’s Backplane

Plug one end of the FlexBus 3500 stack cable (provided with the base package) in the Out port of the top hub and the other end to the In port of the next hub. Repeat this step for each hub in the stack. Form a simple chain starting at the Out port on the first hub and ending at the In port on the last hub. Refer to FlexBus Ports in Chapter 5 for related information.

ΦHubs in a stack can only be grouped into segments through the FlexBus 3500 stack cable. You should therefore use the FlexBus ports to make Out to In connections in a stack.

Hubs in a stack can only be managed by the network management agent through the stack cable. In a managed stack, you should therefore use the stack ports to make Out to In connections, and include a management agent (i.e., a Fast EtherHub-12mi) in the chain.

You can also cascade hubs using the daisy-chain port (Port 12MDI). However, hubs cascaded using the daisy-chain port cannot be managed by the management agent. See the next section for details.
