1. Technical description 
1.1. General description. 
 ISF108 is a 10-ports PoE switch designed to supply IP cameras operating in IEEE 802.3af/at standard. 
Automatic detection of any devices powered in the PoE standard is enabled at the 1 – 8 ports of the switch. The G1/TP and 
G2/TP ports is used for connection of another network device via RJ45 connector. The switch is fitted with SFP slots (marked as 
G1/SFP and G2/SFP), the use of fiber optic module (GBIC) allows fiber optic transmission. Device has solutions that allow it to 
be  powered  from  two  sources  (emergency  power  supply,  redundant  power  supply)  –  in  case  of  a  failure  of  one  source,  it 
immediately switches to backup one. 
 The LEDs at the front panel indicate the operation status (description in the table 3). The PoE technology ensures a 
network connection and reduces installation costs by eliminating the need to supply a separate power cable for each device. 
This method allows supplying other network devices, such as IP phone, wireless access point or router.
