Introducing the Switch

The HP 1405-5, 1405-5G, 1405-8, and 1405-8G Switches are multiport

unmanaged switches that can be used to build high-performance switched

workgroup networks. These switches are store-and-forward devices that offer

low latency for high-speed networking.

Throughout this manual, these switches will be referred to as the 1405-5

Switch, 1405-5G Switch, 1405-8 Switch, and 1405-8G Switch.

■The 1405-5 Switch has 5 auto-sensing 10/100Base-TX RJ-45 ports.

■The 1405-5G Switch has 5 auto-sensing 10/100/1000Base-T RJ-45 ports.

■The 1405-8 Switch has 8 auto-sensing 10/100Base-TX RJ-45 ports.

■The 1405-8G Switch has 8 auto-sensing 10/100/1000Base-T RJ-45 ports.

These switches can be directly connected to computers, printers, and servers

to provide dedicated bandwidth to those devices, and you can build a switched

network infrastructure by connecting the switch to other switches or routers.

Introducing the Switch

Front of the Switch

Network Ports

The network ports support “Auto-MDIX” feature, which means that you can

use either straight-through or crossover twisted-pair cables to connect any

network devices to the switch.

■5 or 8 auto-sensing 10/100Base-TX ports.

■5 or 8 auto-sensing 10/100/1000Base-T ports (for 1405-5G and 1405-8G

only).

LEDs

The front panels of the switches provide status LEDs for system monitoring.

Table 1-1 details the functions of the LED indicators.

Table 1-1. Switch Status LEDs

Introducing the Switch

Back of the Switch

Power Connector

The switches do not have a power switch. They are powered on when the

external AC/DC power adapter is connected to the switch and to a power

source. The external AC/DC power adapter supplies 12 volts DC to the switch

and automatically adjusts to any AC voltage between 100-240 volts and either

50 or 60 Hz. No voltage range settings are required.
