GarrettCom P80C, P80F manual LED’s, Up-link Port # 1 or 1SW, Use with Media Converters

Magnum P80F & P80C Personal Switches Installation and User Guide (07/03)

4.5LED’s

PWR: Illuminates GREEN, steady on when power applied.

ERROR: Indicates the self-test at power up was not successful

SPEED: Per port, ON = 100Mbps; OFF = 10 Mbps (when LINK is made)

LINK/ACT: Per port, steady ON for LINK with no traffic, blinking indicates port is transmitting and receiving.

F/H: ON = Full-Duplex and Link, OFF = Half-Duplex and / or no Link.

4.6Up-link Port # 1 or 1SW

Magnum P80F and P80Cs have one manual crossover (MDIX up-link) switch, port 1SW, on the front of the Personal Switch. This port can operate either Full/Half duplex mode.

The up-link (or cross-over) on the # 1 or 1SW port allows its RJ-45 cable to connect for cascading to another hub or switch port. This allows repeater-to-repeater connections without a special cross-over cable. Port 1 works the same as regular ports for 10 Mbps or 100Mbps speed auto-sensing connections.

Cascaded connections may be operated at either 10 or 100Mbps speed. The P80F even supports cascaded connections of both 10 Mbps and 100Mbps at the same time on different ports. When attaching a 10 Mbps hub or switch, the Ethernet configuration rules (hop count limits, etc.) for 10 Mbps domains are in effect. When the cascaded connection is operated at 100Mbps speed, because of its full duplex and switched port capability, does not need any PDV calculation for distances. Two P80F and P80Cs cascaded using RJ-45 ports will auto-negotiate to operate the connection at 100Mb/s.

4.7 Use with Media Converters

Where an additional fiber connection (beyond the built-in fiber port as on P80F) may be desired, a media converter may be used. For P80F, the first two switched ports can be set to FDX manually, making typical 100Mb media converters (which can be troublesome with auto-negotiating ports, defaulting to 100Mb half-duplex) usable in either HDX or FDX mode as set by the user.

Whereas for P80C the switched port 2 at “F” position supports 100Mbps Full duplex fixed only which is useful for the fast ethernet media converter (e.g. Magnum 15E).
