Radiance 1Gbps Interface Line Cards with SFP Optics 19
Changing the SFP Optics
Depending on the model, the 1Gbps interface line card supports one or two
replaceable small form-factor pluggable (SFP) transceivers for the fiber port(s).
This section explains how to remove and install the optics on the card. Metrobil-
ity SFP transceivers are hot-swappable and can be changed without disrupting
traffic on the other port.
IMPORTANT: Use only Metrobility SFP transceivers with this product.
Installing any other optics may damage the unit and will void the product’s
warranty.
1. Disconnect the fiber optic network cables, if they are installed, from both
the receiver (top) and transmitter (bottom) of the SFP transceiver.
WARNING: Avoid looking into the laser or cable.
2. To remove the SFP optics from the interface line card, simply pull the
release mechanism (i.e., plastic tab, release wire, etc.) and slide the module
out of the slot, as shown below.
