Radiance 1000Mbps Redundant Interface Line Cards 23
Changing the SFP Transceiver
Depending on the model, the fiber ports on 1000Mbps redundant interface line
card supports two or three replaceable small form-factor pluggable (SFP)
transceivers. This section explains how to remove and install the parts into the
card. Metrobility SFP transceivers are hot-swappable and can be changed
without disrupting traffic on the other ports.
IMPORTANT: Use only Metrobility SFP transceivers with this product.
Installing any other part 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 transmitter (TX) and receiver (RX) ports of the SFP transceiver.
WARNING: Avoid staring into the laser beam coming from the cable.
2. To remove the SFP transceiver from redundant 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.
