Powering On the Switch

Quick Installation Guide

1000BASE-SX and 1000BASE-LX fiber optic cable depends on the core size and the rating of the cable, as shown in the following tables.

Maximum 1000BASE-SX Gigabit Ethernet Cable Length

Fiber Size	Fiber Bandwidth	Maximum Cable Length
62.5/125 micron	160 MHz/km	2-220 m (7-722 ft)
multimode fiber
multimode fiber	200 MHz/km	2-275 m (7-902 ft)
	200 MHz/km	2-275 m (7-902 ft)

50/125 micron	400 MHz/km	2-500 m (7-1641 ft)
multimode fiber
multimode fiber	500 MHz/km	2-550 m (7-1805 ft)
	500 MHz/km	2-550 m (7-1805 ft)


Maximum 1000BASE-LX Gigabit Ethernet Cable Length
Fiber Size	Fiber Bandwidth	Maximum Cable Length

9/125 micron	N/A	2 m - 5 km (7 - 16404 ft)
singlemode fiber

1.Plug the power cord into the power socket on the rear of the switch, and the other end into a power outlet. (If you have purchased a redundant power supply, plug it into the “DC INPUT” receptacle on the rear of the switch.)

2.Check the LED marked Power on the front panel to see if it is on. The unit will automatically select the setting that matches the connected input voltage. Therefore, no additional adjustments are necessary when connecting it to any input voltage within the range marked on the rear panel.

3.The switch performs a self-diagnostic test upon power-on. (Note that this test takes several minutes to complete.)

Note: The unit supports a “hot remove” feature which permits you to connect or disconnect twisted-pair or fiber cables without powering off the switch and without disrupting the operation of the devices attached to the switch.
