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.

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.

Switch LEDs State Meaning
HP Power LED
(white)
On The switch is properly receiving power.
Off No power connection. The switch is NOT receiving power.
Port LEDs
Link/Act
(blue)
On The port is enabled and receiving a link indication from the connected device.
Off One of these condition exists:
• no active network cable is connected to the port
• the port is not receiving link beat or sufficient light
Flashing1Indicates that there is network activity on the port.
1The flashing behavior is an on/off cycle once every 0.083 seconds approximately.

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.
