• 7510. Safety recommendations To avoid possible bodily injury and equipment damage, read the safety recommendations in this chapter carefully before installing an HPE 7500 switch. The recommendations do not cover every possible hazardous condition. General safety recommendations • Keep the chassis clean and dust-free.
The HPE 7500 switches are class 1 laser products. Examining the installation site The HPE 7500 switches can only be used indoors. To ensure correct operation and long service life of your switch, the installation site must meet the requirements in this section.
Table 1 Temperature requirements Temperature Range Operating temperature 0°C to 45°C (32°F to 113°F) Storage temperature –40°C to +70°C (–40°F to +158°F) Humidity Maintain appropriate humidity in your equipment room, as described in Table • Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property change of materials, and metal corrosion.
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in the following ways: • A conduction pattern of capacitance coupling. • Inductance coupling. • Electromagnetic wave radiation. • Common impedance (including the grounding system) coupling. To prevent EMI, perform the following tasks: •...

Installing accessories to the chassis Installing mounting brackets and cable management brackets Before installing the switch in the rack, install the mounting brackets and cable management brackets shipped with the switch.
Page 22
• Other models—Install the cable management brackets to the mounting brackets, and then install the mounting brackets to the chassis. For more information, see "Installing the cable management brackets on other models" and "Installing the mounting brackets." Installing the cable management brackets on the 7506-V The 7506-V has two cable management brackets: the one with a tray is installed at the lower part of the switch, and the one without a tray is installed at the upper part of the switch.
Figure 11 Installing the cable management bracket to the left mounting bracket Installing the mounting brackets Before installing the switch in the rack, install the mounting brackets to the chassis, as shown Figure • 7506-V—Facing the front of the switch, mount the left and right mounting brackets to the two sides of the switch.

For the installation procedures, see "Installing an air filter on a 7506-V." • Other models—The air filter is located at the left of the chassis. For the installation procedures, "Installing an air filter on other chassis models."...
Figure 14 Installing an air filter (7503) Mounting the switch in the rack CAUTION: • Do not hold the handle of the fan tray, power supply, or the back cover of the chassis, or the air vents of chassis to move the switch. Any attempt to carry the switch with these parts might cause equipment damage or even bodily injury.
Figure 15 Installing the chassis in the rack (7503) NOTE: If the screw holes in the mounting brackets cannot align with the cage nuts on the rack, verify that the bottom edge of the slide rail aligns with the middle of the narrowest metal area between holes and that the cage nuts are installed in the correct holes.
Figure 16 Connecting the grounding cable to a grounding strip Grounding the switch through the AC power supply CAUTION: • Make sure the AC power supply uses a three-wire cable with a protection wire, and the AC power cord is reliably grounded at the power distribution room or AC power supply transformer side.
Grounding the switch through the RTN wire of a DC power supply CAUTION: Make sure the RTN busbar in the equipment room is reliably grounded. If the switch is powered by a –48 VDC power supply and no grounding strip is available at the installation site, you can ground the switch through the return (RTN) wire of the DC power supply, as shown in Figure...

Appendix F Engineering labels Engineering labels are used to identify cables and devices for easy maintenance after installation. There are two types of engineering labels, labels for cables and labels for devices. Labels for cables Cables include signal cables such as network cables and fibers, and power cords such as AC power cords and DC power cords.
Figure 80 Label for power cords (1) Cable tie (2) Dividing line on the label Generic labels A generic label is bar-shaped with fixed dimensions. It is applicable to both signal cables and power cords. A mark "TO:" is located at the upper left corner in the right area of the label to identify the peer end of the cable on which the label is affixed.
Figure 81 Generic label (1) Dividing line on the label (2) Cut dotted line Labels for devices A device label is used to identify the device name, model, address, installation date, and so on. Filling in labels You can print or write desired contents on labels. As a best practice, print labels. To print labels, select a label printer and a proper label template as needed.
Figure 82 Affixing a label Stick side B02 03 Figure 83 shows the affixed labels when the cable is laid vertically and horizontally. Figure 83 Affixed labels 03 12 Affixing a label to a power cord Stick the label to the recessed rectangular area on the identification plate. You can stick the label to either side of the identification plate.
Figure 84 Affixing a label Bind cable ties on both ends of a cable. After the bundling, the finished identification plate should be on top of the cable in horizontal cabling, or on the right side of the cable in vertical cabling. Make sure the label is facing out, as shown in Figure Figure 85 Affixed labels...

Table 90 Information on labels affixed to DC power cords Content Meaning • Loaded cabinet side—Only MN is used to identify the cabinet number (row number and column number in the equipment room). MN(BC)-–48Vn • Power cabinet side—MN identifies the row and column number of the power distribution equipment like the control cabinet and distribution box.
RTN cables are covered with insulating sheath, so the labels only need to contain "AC" and the cabinet number. The labels for AC power cords are affixed to one side of the identification plates on cable ties. Table 91 Information on labels affixed to AC power cords Content Meaning MN: Rack number (row number and column number in the equipment room) or the...
