NOTE:

· Rack Unit (RU) is a measurement unit used to indicate the height of a rack. 1 RU is equal to 44.45 mm (1.75 in).

· Table 3 lists dimensions for the switch, excluding the mounting brackets, cable management brackets, modules, and power supplies.

Total power consumption

The total power consumption of a switch is the sum of the power consumptions of all running modules and fan trays, depending on the type and quantity of the modules installed and the power consumption of the fan trays. The total power consumption can be calculated as follows:

· Minimum total power consumption of the switch = Minimum total power consumption of the modules + minimum power consumption of the fan trays.

· Typical total power consumption of the switch = Typical total power consumption of the modules + typical power consumption of the fan trays.

· Maximum total power consumption of the switch = Maximum total power consumption of the modules + maximum power consumption of the fan trays.

For example, for an S10506X-G switch that has two LSEM1SUPA0 MPUs, two LSEM1GT48TSSD0 service modules, two LSEM1SF06D0 switch fabric modules, and two FAN-80B-4-A fan trays:

· The minimum total power consumption of the switch is 2 × 22 + 2 × 28 + 2 × 55 + 2 × 30 = 270 W.

· The typical total power consumption of the switch is 2 × 23 + 2 × 47 + 2 × 63 + 2 × 100 = 466 W.

· The maximum total power consumption of the switch is 2 × 30 + 2 × 55 + 2 × 95 + 2 × 230 = 820 W.

Heat dissipation

Heat dissipation is measured in BTU/h, and 1 W equals 3.4121 BTU/h.

The heat dissipation of a switch depends on its power consumption. To calculate heat dissipation of the switch, assume 90% power consumption is converted to heat, and the conversion efficiency of the power supplies is 90%. Heat dissipation/hour of the switch is [ 0.9 × (total power consumption of the modules plus power consumption of the fan trays) ] /0.9 × 3.4121.

Table 6 Heat dissipation

Switch module	Heat dissipation (BTU/H)
S10506X-G/S10506X-G-PoE	10216
S10508X-G	14843
S10512X-G	121405

Cooling

For adequate ventilation and heat dissipation, make sure the following requirements are met:

· Make sure the airflow of the chassis matches the airflow direction of the installation site.

· Reserve a minimum clearance of 30 cm (11.81 in) around the inlet and outlet air vents.

· Make sure the rack for the switch has a good cooling system.

· Make sure the installation site has a good cooling system.

Modules

The switch supports varieties of modules that are different in power consumptions. For a same module, the power consumption varies by its state.

· The minimum power consumption of a module refers to the power consumed by the module when it is running with all its ports down and its fiber ports not installed with transceiver modules.

· The typical power consumption of a module refers to the power consumed by the module when it is running with 50% of its ports connected and at 50% load.

· The maximum power consumption of a module refers to the power consumed by the module when it is running with all of its ports connected and at full load.

NOTE:

Module dimensions are expressed in the Height (H) × Width (W) × Depth (D) format:

· Height—Height of the front panel of the module.

· Width—Width of the front panel of the module.

· Depth—Depth from the front panel of the module to the connector (Including the connector, but excluding the ejector levers and captive screws).

Power supplies

The switch supports N+N (dual power inputs) or N+1 (single power input) power supply redundancy. Determine the number of power supplies based on the power supply mode and system power consumption. Make sure the maximum total output power of the installed power supplies is greater than the system power consumption. Reserve a 20% power surplus as a best practice.

IMPORTANT:

When the temperature of a power supply exceeds the upper limit or drops below the lower limit, the power supply shuts down automatically. When the temperature falls into the normal range, the power supply starts up automatically.

AC power cord

An AC power cords is used for connecting an AC power supply on the switch to the external AC power supply system. Select an AC power cord with a current-carrying capacity that meets the power supply requirement.

For a PSR1600B-12A-B power supply, use an IEC 60320 standard-compliant power cord that has a C13 connector (connected to the power supply). For a PSR1600-54A-B power supply, use an IEC 60320 standard-compliant power cord that has a C15 connector (connected to the power supply).

The type of the connector (connected to the power source) varies by country or region. Select a compliant connector type as needed. For the connector types of different countries or regions and the power cord codes, see H3C Power Cords & Cables User Guide.

Ethernet twisted pair cable

An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly transmits analog signals and is advantageous in transmitting data over shorter distances. The maximum transmission distance is 100 m (328.08 ft). To increase the transmission distance, you can install a maximum of four repeaters between two Ethernet twisted pair cables. With four repeaters installed, the maximum transmission distance can reach 500 m (1640.42 ft).

RJ-45 connector

An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two ends. Figure 2 shows the pinouts of an RJ-45 connector.

Based on pinouts

Ethernet twisted pair cables can be classified into straight through and crossover cables based on their pinouts.

· Straight-through—The pinouts at both ends comply with standard 568B, as shown in Figure 3.

· Crossover—The pinouts at one end comply with standard 568B, and those at the other end comply with standard 568A, as shown in Figure 4.

Pin assignments

Select an Ethernet twisted pair cable according to the RJ-45 Ethernet interface type on your device. An RJ-45 Ethernet interface can be MDI (for routers and PCs) or MDIX (for switches). For the pinouts of RJ-45 Ethernet interfaces, see Table 4 and Table 5.

To ensure normal communication, the pins for sending data on one port should correspond to the pins for receiving data on the peer port. When both of the ports on the two devices are MDI or MDIX, a crossover Ethernet cable is needed. A cross-over cable connects devices of the same type. When one port is MDI and the other is MDIX, a straight-through Ethernet cable is needed. A straight-through cable connects devices of different types.

An RJ-45 Ethernet interface with MDI/MDIX autosensing enabled can automatically negotiate pin roles. The S10500X-G RJ-45 Ethernet interfaces support MDI/MDIX. By default, MDI/MDIX is enabled on a port.

Making an Ethernet twisted pair cable

1. Cut the cable to length with the crimping pliers.

2. Strip off an appropriate length of the cable sheath. The length is typically that of the RJ-45 connector.

3. Untwist the pairs so that they can lie flat, and arrange the colored wires based on the wiring specifications.

4. Cut the top of the wires even with one another. Insert the wires into the RJ-45 end and make sure the wires extend to the front of the RJ-45 end and make good contact with the metal contacts in the RJ-45 end and in the correct order.

5. Crimp the RJ-45 connector with the crimping pliers until you hear a click.

6. Repeat the above steps with the other end of the cable.

7. Use a cable tester to verify the connectivity of the cable.

Optical fiber

CAUTION:

Use the same types of transceiver modules, pigtail cords, patch cords, and fiber cables. If you use single-mode optical fibers, the transceiver modules, pigtail cords, patch cords, and fiber cables must be single-mode.

Optical fiber

Optical fibers are widely used in fiber-optic communications, which are advantageous for long-distance communications.

Optical fibers can be classified into the following types:

· Single mode fiber—It has a core size of 10 µm or smaller, and has a lower modal dispersion. It carries only a single ray of light. It is mostly used for communication over longer distances.

· Multi-mode fiber—It has a core size of 50 µm or 62.5 µm or higher, and has a higher modal dispersion than single-mode optical fiber. It is mostly used for communication over shorter distances.

Table 77 Allowed maximum tensile force and crush load

Period of force	Tensile load (N)	Crush load (N/mm)
Short period	150	500
Long term	80	100

Optical fiber cable

An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube. Optical fiber cables fall into single-mode and multi-mode.

Patch cord

A fiber that has connectors at both ends is called a patch cord. A patch cord connects one optical device to another for signal routing. Patch cords fall into single-mode and multi-mode patch cords.

· Single-mode patch cord—The jacket is yellow. It permits transmission over longer distances.

· Multi-mode patch cord—The jacket is orange. It permits transmission over shorter distances.

Patch cords are classified into SC, LC, FC, and so on based on interface type. The length of a patch cord can be 0.5 m (1.64 ft), 1 m (3.28 ft), 2 m (6.56 ft), 3 m (9.84 ft), 5 m (16.40 ft), 10 m (32.81 ft), and so on.

Pigtail cord

A pigtail cord is an optical fiber that has an optical connector on one end and a length of exposed fiber on the other. The end of the pigtail is fusion spliced to a fiber, connecting the fiber cable and transceiver.

Pigtail cords fall into single-mode (yellow) and multi-mode (orange), and can also be classified into SC, LC, FC, and so on based on interface type.

Fiber connector

Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient and the transit dispatching of the system more flexible.

Precautions

· Make sure the fiber connector and fiber type match the transceiver module type.

· The fiber ports on the switch are provided with dust plugs. Insert the dust plugs into the fiber ports that you are not to use, to prevent particles from entering the ports.

· Fiber connectors must be protected under safe and reliable outer packing, and be fitted with dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take care not to scratch their end face. Replace the dust cap if it is loose or polluted.

· Before connecting a fiber, use dust free paper and absolute alcohol to clean the end face of the fiber connector. You can brush the end face only in one direction. You also need to brush the end face of the fiber port.

· Never bend or curve a fiber when connecting it. After a fiber is installed well, the bend radius must be not less than 40 mm (the minimum dynamic bend radius is 20 D, and the minimum static bend radius is 10 D. D indicates the outer diameter of dust caps).

· If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted surface (the filleting radius must be not less than 2 mm). When passing through a metallic board hole or bending along the acute side of mechanical parts, the fiber must wear jackets or cushions.

· Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the plug might be damaged or the fiber might be broken. Never pull, press or extrude the fiber fiercely. For the allowed maximum tensile load and crush load, see Table 6.
