4.2 Switch Topology
Theoretically, the switch partitions the collision domain for each port so you may link switches
without limitations. However, network extension (cascading levels & overall diameter) must
follow IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the
limitations are the timing requirement from physical signals defined by 802.3 series specification
of Media Access Control (MAC) and PHY, and layer 2 protocols such as 802.1d, 802.1q, and
LACP.
The following table describes the cable and devices’ bit-time delay (round trip):

Round trip Delay: 4096 Round trip Delay: 512
CAT5 11.12/m CAT5 1.12/m Fiber Cable: 1.0/m
Fiber 10.10/m TP to fiber converter: 56
Bit time unit: 1ns (1sec./1000 Mega bit)

5.0 LEDs
The following table provides the status and description of the LEDs:
LED Color Function
POWER Green Lit when +5V DC power is on and good
10/100/1000Ethernet TP Port 1 to 8 LED
LINK/ACT Green
Lit when connection with remote device is good
Blinks when any traffic is present
10/100/1000Mbps Green/
Amber
Lit green when 1000Mbps speed is active
Lit amber when 100Mbps speed is active
Off when 10Mbps speed is active

If there is a no link status, the possible causes are as follows:
ƒ
The attached device is not powered on.
ƒ
The cable may not be the correct type or is faulty.
ƒ
The installed building premise cable is faulty.
ƒ
The port may be faulty.
