Management Port (RJ-45)
The SMC8708L2 contains one 10/100BASE-TX management port
(labeled Mgmt) that operates at 10 Mbps or 100 Mbps, half or full duplex.
This port is provided only for management access, and does not allow
pass-through or data traffic.
Note: It is also possible to manage the switch through the switch’s XFP
transceiver slots.
The management port supports automatic MDI/MDI-X operation, so
you can use straight-through cables for all network connections to PCs or
servers, or to other switches or hubs. (See “10BASE-T/100BASE-TX Pin
Assignments” on page B-2..)
This port supports auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected
automatically. If a device connected to this port does not support
auto-negotiation, the communication mode of that port can be configured
manually. It also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
