Port Description

10/100/1000BASE-T port
A 10/100/1000BASE-T Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s, and must use an Ethernet cable. Table 4-720 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.

-

  • When you press this button once, the mode indicator turns green and the service port indicators show the speed of each service port.
  • When you press this button a second time, the mode indicator turns red and the service port indicators show the stack status.
  • When you press this button a third time, the mode indicator turns yellow and the service port indicators show the PoE status.
  • When you press this button a fourth time, the mode indicator turns off.

If you do not press the button within 45 seconds, the mode indicator restores to status mode.

Figure 4-288 shows the power supply mode of dual AC PoE power modules (PWR1 and PWR2). After AC power is transmitted to the PWR modules, the PWR modules provide 12 V and -53 V outputs. The outputs are combined on the motherboard, which then provides 12 V voltage for the switch and -53 V voltage for the PDs.
