Alteon Web Switch Hardware Installation Guide
5.Connect the other end of each DC power lead to the appropriate wire terminal of your DC power source.
Connect the DC “+” (common) switch terminal to the source DC “+” common power terminal. Connect the DC “–” (-48) switch terminal to -48 VDC source relative to common.
CAUTION—Be certain that the DC power leads are correctly connected. Improper power con- nection can damage the switch’s internal fuse.
CAUTION—The fuse can be accessed by unscrewing the fuse cover on the rear panel. Replace only with a fast-acting, 3A, 125VDC-rated fuse for continued protection against risk of fire.
The fuse must be rated for DC power.
6.Install the terminal block safety cover.
7.Turn DC power on at the source.
Connecting Cables to Network Ports
Each network port on Alteon 180 series Web switch has two connector jacks: one RJ-45 jack for connecting 10/100 Mbps Ethernet segments to the port, and one SC jack for connecting 1000 Basic SX Gigabit Ethernet fiber optic segments.
Each network port on Alteon AD series Web switch has only one connector jack: RJ-45, for connecting 10/100 Mbps Ethernet segments to the port.
All ports support full-duplex operation. The 10/100 Mbps ports auto-negotiate, and also sup- port half-duplex operation. On Alteon 180 Web switches, only one of the two jacks can be active at any given time for any port, according to conditions described in “Automatic Selec- tion of Redundant Connections” on page 22.
The port LEDs light to indicate various port connection conditions. See Table 3 on page 13 for details.
