The LEDs and ports are located on the front panel of the Switch..
Front Panel
POWER (Green/Amber) Lights up green to indicate that power is being supplied to the Switch.. Lights amber to indicate that the Switch’s power-on-self-test (POST) is in progress.. Blinks amber to indicate that the POST has failed..
LINK/ACT (1-24) (Green/Amber) Lights up green to indicate a functional 10/100Mbps network link through the corresponding port with an attached device that does not use Power over Ethernet (PoE).. Lights up amber to indicate a functional 10/100Mbps network link through the corresponding port with an attached PoE device.. Blinks green to indicate that the Switch is actively sending or receiving data over that port..
LINK/ACT (G1-G4) (Green/Amber) Lights up green to indicate a functional 10/100Mbps network link through the corresponding port with an attached device.. Blinks green to indicate that the Switch is actively sending or receiving data over that port.. Lights amber to indicate a functional 1000Mbps network link.. Blinks green to indicate that the Switch is actively sending or receiving data over that port.. No amber light indicated that the link is at 10/100Mbps or there is no link..
Product Overview
ETHERNET 1-24 These RJ-45 ports support network speeds of either 10Mbps or 100Mbps, and can operate in half and full-duplex modes.. Auto-sensing technology enables each port to automatically detect the speed of the device connected to it (10Mbps or 100Mbps), and adjust its speed and duplex accordingly..
The Switch’s 10/100 RJ-45 ports also support the IEEE 802..3af Power-over-Ethernet (PoE) standard that enables DC power to be supplied to attached devices using wires in the connecting twisted-pair cable.. Any 802..3af-compliant device attached to a port can directly draw power from the Switch over the twisted-pair cable without requiring its own separate power source.. This capability gives network administrators centralized power control for devices such as IP phones and wireless access points, which translates into greater network availability..
For each attached 802..3af-compliant device, the Switch automatically senses the load and dynamically supplies the required power.. The Switch delivers power to a device using the two data wire pairs in the twisted-pair cable.. Each port can provide up to 15..4W of power at the standard -48 VDC voltage..
To connect a device to a port, you will need to use Category 5 (or better) network cable..
ETHERNET G1-G4 The Switch is equipped with four Gigabit RJ-45 ports, two that are shared with two miniGBIC ports.. If a Gigabit miniGBIC port is being used, the associated RJ-45 port (G3 and/or G4) cannot be used..
All four ports support auto‑negotiation, so the optimum transmission mode (half or full duplex) and data rate (10, 100, or 1000 Mbps) can be selected automatically, if this feature is also supported by the attached device.. If a device connected to one of these ports does not support auto-negotiation, the communication mode of that port can be configured manually..
Each port also supports IEEE 802..3-2002 auto‑negotiation of flow control, so the Switch can automatically prevent port buffers from becoming saturated..
These ports support automatic MDI/MDI-X operation, so you can use straight-through cables for all network connections to PCs, servers, or additional switches..
