SwitchBlade x3112 Installation Guide

slot in the top row is port number 0 because it is the lower of the two port

numbers of the slot. To configure the transceiver, you have to specify port

0 in the management software. The switch marks the unused port number

of the slot, in this case port number 2, as masked or eclipsed to prevent

you from using it to manage the transceiver.

In contrast, an SFP module in a slot in the bottom row is assigned the

higher number of the slot’s two numbers. For instance, an SFP transceiver

installed in the first slot in the bottom row is assigned the port number 3 by

the switch. Port 1, the unused port number of the slot, is marked as

masked by the switch and cannot be used to configure the device.

Figure 19 illustrates the port numbers for the first four slots when they

contain standard SFP transceivers.
