To ensure correct operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections. Temperature/humidity Maintain temperature and humidity in the equipment room as described in "Environmental specifications." • Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property change of materials, and metal corrosion.

To prevent EMI, use the following guidelines: • If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid. • Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.
Installing the switch WARNING! Before installing or moving the switch, remove the power cord. You can install an HPE 1620 switch in a 19-inch rack, on a workbench, or on a wall. Mounting the switch in a 19-inch rack by using mounting brackets The HPE 1620 24G and HPE 1620 48G switches have the same width.

Mounting the switch on a workbench IMPORTANT: • Reserve a clearance of 10 cm (3.9 in) around the chassis for heat dissipation. • Do not place heavy objects on the switch. To mount the switch on a workbench: Verify that the workbench is sturdy and reliably grounded. Place the switch bottom up, and clean the round holes in the chassis bottom with a dry cloth.

Figure 7 Hole spacing Insert one wall anchor into each hole until the anchors are flush with the wall surface. Drive one screw into each wall anchor, and tighten the screws just enough to keep it secure in the wall anchor. Leave a minimum clearance of 1.5 mm (0.06 in) between the base of the screw head and the wall anchor so the switch can hang on the screws securely.
Connecting cables Connecting network cable Use crossover cable or straight through cable to connect a PC or other network devices to the Ethernet port of the switch. Figure 10 Connecting network cable Connecting the console cable To connect a terminal (for example, a PC) to the switch: Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
NOTE: To disconnect the console cable, remove the RJ-45 connector of the cable and then the DB-9 female connector. Connecting the AC power cord Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. Connect one end of the grounding cable to the grounding screw on the rear panel, and connect the other end to the ground.
Accessing the switch for the first time Setting up the configuration environment The first time you access the switch you must use a console cable to connect a console terminal, for example, a PC, to the console port on the switch. Figure 13 Connecting the console port to a terminal Connecting the console cable Console cable...
Connection procedure CAUTION: The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end. To connect a terminal (for example, a PC) to the switch: Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
