Figure 2: Rear panel
The switches feature a Universal Serial Bus (USB) port on the front panel. Switch administrators can use the USB port to perform tasks, previously performed through Trivial File Transfer Protocol (TFTP), with a USB Mass Storage Device (for example, a flash drive or thumb drive):
•download software
•generate and download the ASCII configuration file
•generate and download the binary configuration file
The storage capacity of the USB device in use limits file and system operations.
Support is available only for USB drives that comply with the Mass Storage subsection of the USB 1.1 and USB 2.0 specification. Support does not extend to third-party devices that do not comply with these standards. Off-the-shelf drives that do not comply with these standards cannot operate with the switch. Only FAT or FAT32 file systems are currently supported; USB drives with NTFS file systems are not supported. Consult the documentation provided with the USB drive to ensure compliance with these standards.

Electrostatic discharge prevention
This module provides information and procedures for the prevention of electrostatic discharge during the installation process.
Electrostatic discharge (ESD) is a discharge of stored static electricity that can damage equipment and impair electrical circuitry. These electrostatic voltages can result from friction, including, but not exclusive to, pulling cabling through conduits, walking across carpeted areas, and building up of static charge in clothing. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures. While networking equipment is commonly designed and tested to withstand common mode ESD events, voltage sometimes can be discharged to some connector pins but not others, or to some pins before others, which has the potential to damage the networking equipment.
To protect the switch against ESD damage, take the following preventive measures before connecting any data cables to the device:
•Always use antistatic wrist straps. Make sure the strap is adjusted to provide good skin contact.
•Ensure that work surfaces and equipment racks are properly grounded for protection against electrostatic discharge. The common point must be connected to the building ground wire. In a properly wired building, the nearest reliable ground is typically at the electrical outlet.
•Avoid contact between equipment and clothing. The wrist or ankle strap only protects the equipment from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•Avoid touching any connector pins.
•Do not remove the wrist or ankle strap until the installation is complete.
With new cable installations, you should use an ESD discharge cable to reduce the potential for damage from static that can build up in cables. See the following figure.

Installation preparation
The following table provides the technical specifications for the switches in this series. Ensure that the area where you install the switch and where it operates meets these requirements.
Warning:
To avoid bodily injury from hazardous electrical shock and current, never remove the top of the device. No user-serviceable components are inside.

|
• At least 2 inches (5.08 cm) on each side of the |
|
switch unit for ventilation |
|
• Cables should be dressed to prevent blocking air |
|
flow. |
