    The ETHUB16 provides a complete 10Base- T rack mount Hub solution for your 10Base- T 10Mbps Ethernet local area 
network.  As a wiring hub the ETHUB16 offers 16 UTP (Unshielded Twisted Pair) ports.  The ETHUB16 includes a daisy-
chain port for Hub-to-Hub connection, true repeater functionality, internal universal power supply and a modular slot that 
allows connection to a 10Base-2 (BNC), 10Base-5(AUI) and 10BASE-FL (Fiber-optic) cabled networks. 
 
Features: 

•

  Complies with IEEE 802.3 

•

  16 UTP (unshielded twisted pair) ports 

•

  1 daisy-chain port (activated by a switch) 

•

  Automatic partition capability for STP ports 

•

  1 AUI port 

•

  1 Module slot  (for AUI, BNC and 10Base-FL modules) 

•

  “Hot swapping” of optional module 

•

  LED indicators:  Power, Collision, LK/RX for each port; 

 

Partition for each port 

•

  Universal Internal Power Supply:  AC 90 V – 260V/ 47-63Hz 

•

  High quality 19” rack mount case 

•

  Dimensions:  220 x 429 x 43 mm  (8 2/3” x 17” x 1 ¾”) 

•

  FCC Class A, CE mark 

 
Daisy-chain switch: 
 

The first UTP port can be used as a daisy-chain link to another hub. Set the switch to the daisy-chain position to 

enable this function. Connect a UTP cable from the daisy-chain port to another hub’s regular port (not its daisy-chain 
port). 
 
Hub Ports: 
 

The hub supports 16 RJ-45 connectors for 10Base- T specification connections. The maximum distance is 100 m 

(328 ft.). The first UTP port can be used to connect to another hub. The ETHUB16 also comes with a standard AUI 
10Base- 5 port and a module slot for adding an optional 10Base- 5, 10Base- 2, or a 10Base FL module. 
 
LED Indicators: 
 

Power 

LED on 

Red colored LED is on to indicate that the power is on 

TX/RX LED 

Flashes 

Green colored LED flashes to indicate network traffic on the dedicated AUI port or the 
optional module port 

Link/ 
Activity 

LED on 

One for each port –Green LED when on indicates the port is connected to a node 

LED off 

Indicates no connection or a poor connection – possible reasons include: 
a)  No connection between port and node 
b)  The twisted pair cable is faulty 
c)  The cable exceeds the permitted length of 100 meters (328 feet) 
d)  A non-10Base- T device is connected at the node 

 

LED 
Flashes 

Green LED flashes when the port is transmitting data 

Partition 

LED on 

Red colored LED is on when the hub detects faulty signals on a port and isolates that port
