ENTERPRISE-Class managed layer 2/4 10/100 switching for workgroups, with a choice of gigabit downlinks and stacking; ieee 802.1x radius network login provides secure network access control at the edge of the network; HOT-Swappable stacking of up to eight units, or 384 10/100 ports, allows continuous operation of the network; switches automatically select the optimal speed and duplex mode of connected cables to prevent misconfiguration of the network; network management is available through an embedded web and command line interface, cli, or via an snmp management station
An item that provides the facilities for data concentration and acts as a switching node to provide a dynamic routing system. It performs data path management, data flow rate control and automatic traffic re-routing.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
