ZT 8101 10/100 Ethernet Switch Technical Product Specification
Item
This switch tells the hot swap controller if the user wants to remove the
card. While this switch is closed, the card cannot physically be removed.
This blue LED tells the user it is safe to remove the ZT 8101 switch. If this
LED is not on, damage to the chassis, the ZT 8101 switch, or modules in
the chassis could result by removing the ZT 8101 switch.
There are 4 RJ-45 ports. Two of them are for 10BASE-T/100BASE-TX
Ethernet ports and two of them are for 100BASE-TX/1000BASE-T
Ethernet ports.
The status LED shows the health of the board and its power state.
The serial port allows the user to attach a terminal or a PC running
terminal emulation software (such as HyperTerminal) and manage the
switch.
These LEDs indicate either the activity or the speed of the ports.
