When you insert a cable into the switch’s RJ-45 port, the switch automatically performs
the following actions:
•
Senses whether the cable is a straight-through or crossover cable.
•
Determines whether the link to the attached device requires a normal connection
(such as when you are connecting the port to a computer) or an uplink connection
(such as when you are connecting the port to a router, switch, or hub).
•
Automatically configures the RJ-45 port to enable communications with the attached
device. The Auto Uplink technology compensates for setting uplink connections
while eliminating concern about whether to use crossover or straight-through cables
when you attach devices.
For the following models, some limitations exist for half-duplex mode:
•
Model M4300-28G supports half-duplex mode on ports 1 to 16 only.
•
Model M4300-28G-POE+ supports half-duplex mode on ports 1 to 16 only.
•
Model M4300-52G supports half-duplex mode on ports 1 to 16 and ports 25 to 40
only.
•
M4300-52G-POE+ supports half-duplex mode on ports 1 to 16 and ports 25 to 40
only.
10GBASE-X, 1000BASE-X, and 1000BASE-T transceiver
modules and cables for SFP+ ports
To enable high-speed fiber and Gigabit Ethernet, short- and long-distance connections
on the switch, SFP+ ports can accommodate standard 10G SFP+ and 1G SFP transceiver
modules and direct attach cables (DACs), all of which are sold separately.
The switch supports the following NETGEAR SFP and SFP+ transceiver modules and
cables:
•
Short-reach fiber transceiver modules:
- AGM731F. SFP transceiver 1000BASE-SX, SFP multimode LC GBIC
- AXM761. SFP+ transceiver 10GBASE-SR, SFP+ multimode LC GBIC
•
Long-reach fiber transceiver modules:
- AGM732F. SFP transceiver 1000BASE-LX, SFP single mode LC GBIC
- AXM762. SFP+ transceiver 10GBASE-LR, SFP+ single mode LC GBIC
- AXM764. SFP+ transceiver 10GBASE-LR Lite, SFP+ single mode LC GBIC
