Making a Connection via an MDI Daisy-Chain Port
To make a direct connection to another compatible switch or hub, follow these
steps:
1. Use Port 24 on the switch, and set it to MDI for a daisy-chain connection.
2. Prepare straight-through shielded or unshielded twisted-pair cables with
RJ-45 plugs at both ends. Use 100Ω Category 3, 4 or 5 cable for standard
10Mbps Ethernet connections, or 100Ω Category 5 cable for 100Mbps Fast
Ethernet connections.
3. Connect one end of the cable to Port 24 MDI on the switch, and the other end
to any MDI-X station port on the other device. When inserting an RJ-45 plug,
be sure the tab on the plug clicks into position to ensure that it is properly
seated.
Notes: 1. Alternatively, you can connect from an MDI-X port on the switch to an MDI
daisy-chain port on the other device. Or attach crossover cabling to
(MDI-X) station ports at both ends.
2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet).
Restrictions on Cascade Length - The IEEE 802.3 standard recommends
restricting the number of hubs (i.e., repeaters) cascaded via twisted-pair cable
to 4; while IEEE 802.3u provides even stricter recommendations for Fast
Ethernet. Therefore, when cascading devices other than this switch, please refer
to the accompanying documentation for cascade restrictions. However, note that
because switches break up the path for connected devices into separate collision
domains, you should not include the switch or connected cabling in your
calculations for cascade length involving other devices.
Powering On the Switch
1. Plug the power cord into the power socket at the rear of the switch, and the
other end into a power outlet.
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage.
Therefore, no additional adjustments are necessary when connecting it to any
input voltage within the range marked on the rear panel.
3. The switch performs a self-diagnostic test upon power-on. (Note that this test
takes about 10 seconds to complete.)
Note: The unit supports a hot remove feature which permits you to connect/
disconnect RJ-45 cables without powering off the switch and without
disrupting the operation of the devices attached to the switch.
