Model: MIL-4511H 6
Installation of the Interconnect Cable
The interconnect cable is used to connect multiple hubs in a stack. The connector
at the end of the cable is a 6-wire, straight-through, RJ-11 connector. Connect the
interconnect cable into one of the Stack In/Out ports.
Note:
Connect the RJ-11 connector into the Stack-In/Out ports only. The other 24 ports are for
RJ-45 connectors. Stacking Multiple Hubs
To stack multiple hubs:
1. Place the MIL-4511H managed hub on top of the stack
2. Connect an RJ-11 connector with straight-through, 6-wire data cable into the
“Stack/Out” port to the “Stack/In” port on the first MIL-45114511H.
3. On the first 4511H hub, connect another cable in the “Stack/Out” port to the
“Stack/In” port on the next MIL-4511H (see Figure 3).
Figure 3.Stacking Multiple Hubs
4. Continue until all of the hubs are cascaded to the MIL-4511H. W
When cascading the hubs, the maximum total distance is 25 meters. For two
MIL-4511H hubs used in a stack, the maximum total distance in creases to 50
meters (with one, MIL-4511H on top; eight, MIL-4511Hs in the middle; and
one, MIL-4511H on bottom.
Note:
Connecting a stack of hubs is for SNMP management purposes only. Do not use a stack
for Ethernet connections.The MIL-4511H should always be at the top of the stack. If a
second MIL-4511H is to be used in the stack, place it on the bottom. If the first MIL-4511H
fails, the second MIL-4511H takes control of the stack.
