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 4-440 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.

Combo port
A combo port refers to a pair of ports consisting of an optical Ethernet port and an electrical Ethernet port on the panel. Each combo port matches only one internal forwarding port. A combo port can be configured as an electrical port or an optical port, but only one port can be active at a time. When one port is active, 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 is connected to a console for on-site configuration. The port must use a console cable. The console port is used when a switch is powered on for the first time. For details about the attributes of a console port, see Table 4-441.

Default value: 9600 bit/s

ETH management port
You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely. The port must use an Ethernet cable. You can choose to download the software package through the ETH management port in the BootROM menu. File transfer through the ETH management port is faster than transfer through the console port. For details on how to use the ETH management port, see the Configuration Guide - Basic Configurations. Table 4-442 describes the attributes of an ETH management port.

USB port
The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB flash drive used on a switch must comply with USB 1.1.
NOTE:
USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

Indicator Description

The S5700-48TP-PWR-SI has the same types of indicators as the S5700-28C-PWR-SI. For details, see Indicator Description.

Power Supply Configuration

The S5700-48TP-PWR-SI has two power module slots, each of which can have a 500 W or 250 W power module installed. A power module can provide 369.6 W or 123.2 W of PoE power for powered devices (PDs). Table 4-443 lists its power supply configurations.

Table 4-443  Power supply configurations
Power Module 1 Power Module 2 Available PoE Power Maximum Number of Ports (Fully Loaded)
250 W 123.2 W
  • 802.3af (15.4 W per port): 8
  • 802.3at (30 W per port): 4
500 W 369.6 W
  • 802.3af (15.4 W per port): 24
  • 802.3at (30 W per port): 12
250 W 250 W 246.4 W
  • 802.3af (15.4 W per port): 16
  • 802.3at (30 W per port): 8
500 W 500 W 739.2 W
  • 802.3af (15.4 W per port): 48
  • 802.3at (30 W per port): 24
NOTE:
When a switch has two power modules installed, the two power modules work in redundancy mode to provide power for the chassis and in load balancing mode to provide power for PDs.
Figure 4-166 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.

Heat Dissipation

The S5700-48TP-PWR-SI uses pluggable fan modules for forced air cooling. Air flows in from the left and right sides, and exhausts from the rear panel.

NOTE:
This figure only shows the airflow direction and does not depict the actual device.
