C H A P T E R 2 | Intel Express 100BASE- TX Stackable Hub |
CAUTION
Check that the screw locks on the cable connectors are fully tightened and the cable connection is secure. A faulty cable connection could disrupt the operation of the entire stack.
NOTE
You may need an assistant to remove a hub from a stack that is located on a table or a shelf.
CAUTION
Removing a hub removes port connectivity for that hub from the network. When you remove a hub from the middle of the stack (a hub that is in the middle of the stack is any hub that is located between two operating hubs), you split the Ethernet segment into two separate segments.
d.Tighten the screw locks on the cable connectors to secure the plug to the hub.
e.Repeat steps a through d for all the hubs in the stack.
3.Connect the power cords to the AC power receptacles on the rear panel of all the hubs in the stack.
Connect the power cord to the AC power receptacles on the hub and then to the power outlet.
Removing an Express hub
This section provides instructions for removing an Express hub from a stack. When removing an Express hub from a stack, follow this sequence:
1.Disconnect power cords from the AC power receptacle on the hub rear panel.
All power sources should be disconnected. To verify that power sources are disconnected, check that the Pwr LED on the hub front panel is off.
2.Disconnect the cascade cables from the Cascade Down and Cascade Up connectors on the hub rear panel.
Save the cascade cable that was removed with the inoperable hub for later use.
3.Connect the free end of the cable connected to the Cascade Down connector on the hub above the inoperable hub to the Cascade Up connector on the hub below the inoperable hub.
