Grounding the switch by using the PE wire of the AC power cord If the installation site does not have any grounding strips or earth ground, you can ground an AC-powered switch through the PE wire of the AC power cord. Make sure the following requirements are met: •...
Page 26
To connect an AC power cord for the switch that is not provided with a power cord retaining clip: Insert one end of the AC power cord to the AC-input receptacle on the rear panel of the chassis, as shown in Figure Connect the other end of the AC power cord to the AC power source.
Figure 28 Connecting an AC power cord (3) Connecting an RPS DC power cord IMPORTANT: The RPS DC power cord must be a minimum of 3 m (9.84 ft) long. Only the S5120-28P-HPWR-SI switch supports RPS DC power input. To connect an RPS DC power cord: Correctly orient the RPS DC power cord plug and insert the plug into the DC-input receptacle.
Verifying the installation Before powering on the switch, verify that the following requirements are met: • Sufficient clearance is reserved around the switch for heat dissipation. • The rack or workbench is stable. • The grounding cable is connected correctly. •...
Accessing the switch for the first time Setting up the configuration environment To set up the configuration environment, use a console cable to connect a terminal (a PC in this example) to the console port on the switch. Figure 30 Connecting the console port to a PC Connecting the console cable A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the console port of the switch, and a DB-9 female connector at the other end for...
For more information about Boot ROM menu options, see the release notes for the device. After the startup completes, you can access the CLI to configure the switch. For more information about the configuration commands and CLI, see H3C S5120-SI Switch Series Configuration Guides and H3C S5120-SI Switch Series Command References.
• An S5120-SI switch cannot form an IRF fabric with non-S5120-SI switches. You can use H3C IRF technology to connect and virtualize multiple S5120-SI switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.
NOTE: IRF member switches will automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see H3C S5120-SI Switch Series IRF Configuration Guide.
Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID. Planning IRF topology and connections You can create an IRF fabric in daisy chain topology, or more reliably, ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology.
Identifying physical IRF ports on the member switches Identify the GE ports for IRF connections on the member switches according to your topology and connection scheme. Planning the cabling scheme You can use the GE twisted pair cables, SFP transceiver modules and optical fibers, or SFP network cables to connect the S5120-SI switches for IRF connections.
IRF port binding before or after connecting IRF physical ports depending on the software release. • Execute the display irf configuration command to verify the basic IRF settings. For more information about configuring basic IRF settings, see H3C S5120-SI Switch Series IRF Configuration Guide. Connecting the physical IRF ports CAUTION: Wear an ESD wrist strap when you connect cables or transceiver modules and optical fibers.
To avoid IP address collision and network problems, configure a minimum of one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see H3C S5120-SI Switch Series IRF Configuration Guide.
PoE switches support over-temperature protection, allowing the internal power module to enter the protection state if the temperature is too high and then restore power supply after the temperature returns to the acceptable range. If the problem persists, contact H3C Support. RPS power input failure Symptom The power status LED and RPS status LED are off.
PoE switches support over-temperature protection, allowing the internal power module to enter the protection state if the temperature is too high and then restore power supply after the temperature returns to the acceptable range. If the problem persists, contac H3C Support. Solution 2 To resolve the problem: Verify that the RPS DC power cord is connected correctly.
