Ethernet connections. 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 switch in a stand-alone configuration, you can network up to
8 end nodes.
Caution: Do not plug a phone jack connector into any 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 (328 feet).
2. We advise using Category 5e cable for all network
connections or testing existing Category 5 cable to be
sure that it complies with the IEEE 802.3ab standards.
(See “1000BASE-T Cable Requirements” on page 17.)
Restrictions on Cascade Length - The IEEE 802.3 standard
recommends restricting the number of hubs (i.e., repeaters)
cascaded via twisted-pair cable to four; 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.
