Port Description

10/100BASE-TX port
A 10/100BASE-TX Ethernet electrical port sends and receives service data at 10/100 Mbit/s, and must use an Ethernet cable. Table 4-25 lists the attributes of a 10/100BASE-TX Ethernet electrical port.

Item

Connector type

RJ45

Standards compliance

IEEE802.3, IEEE802.3u, IEEE802.3ab

Electrical port attributes

MDI/MDIX

NOTE:
  • A medium dependent interface (MDI) provides the physical and electrical connection to the cabling medium. Ethernet ports of most NICs are MDIs.
  • A medium dependent interface crossover (MDIX) enables connection between like devices. MDIX ports are usually used on hubs or LAN switches.

Working mode

10/100 Mbit/s auto-sensing

Maximum transmission distance

100 m

Combo port
A combo port consists of an optical Ethernet port and an electrical Ethernet port on the panel. Each combo port matches only one internal forwarding port. The electrical and optical ports of a combo port are multiplexed, and only one of them can work at a time. When one of the Ethernet ports is working, the other port is shut down.
NOTE:

By default, a combo port works in auto mode, in which the port type is determined as follows:

  • If the optical port has no optical module installed and the electrical port has no Ethernet cable connected, the port type depends on which port is connected first. If the electrical port is connected by an Ethernet cable first, the electrical port is used for data switching. If the optical port has an optical module installed first, the optical port is used for data switching.
  • If the electrical port has an Ethernet cable connected and is in Up state, the electrical port is still used for data switching when the optical port has an optical module installed.
  • If the optical port, no matter in Up or Down state, has an optical module installed, the optical port is still used for data switching when the electrical port has an Ethernet cable connected.
  • If the optical port has an optical module installed and the electrical port has an Ethernet cable connected, the optical port is used for data switching after the switch restarts.
You can configure a combo port as an electrical or optical port using the combo-port command.
Console port
The console port of a switch can connect to an operation terminal for onsite configuration. The port must use Console Cable. To configure a switch after the first power-on, log in to the switch through the console port. Table 4-26 lists attributes of a console port.

Default value: 9600 bit/s

Indicator Description

The S2700-9TP-PWR-EI has only one PWR indicator for its unique power module. Symbols and meanings of other indicators on the S2700-9TP-PWR-EI are the same as those on the S2700-52P-PWR-EI. For details, see Indicator Description.

Power Supply Configuration

The S2700-9TP-PWR-EI has a built-in power module and does not support pluggable power modules.

The built-in power module can provide 124 W PoE power, which ensures full PoE power on 8 ports in compliance with 802.3af or on 4 ports in compliance with 802.3at.

Figure 4-14 shows the power supply mode of a built-in AC PoE power module (PWR). The PWR module receives AC power from an external power source and provides two outputs: 12 V and -53 V. The 12 V output is provided for the chassis, and the -53 V output is provided for PDs.

Heat Dissipation

The S2700-9TP-PWR-EI has no fans and uses natural heat dissipation.
