Installing 16 Gbps SFP+ transceivers
Attention: With increasing speeds of optical connections, the cleanliness of the
connections assumes greater importance in ensuring maximum performance and
error free transmission. Due to the tighter tolerances associated with state of the art
optics, levels of contamination that were acceptable at lower speeds may not be at
higher speeds. While IEC Standard 61300-3-35 specifies a set of guidelines for
trouble free performance, most issues can be avoided by adhering to the following
best practices.
v
When cables or connectors are not in use for extended periods of time, use the
dust covers provided.
v
Ensure that the cable length and type that is used are suitable for the speed and
application.
v
Inspect and clean optical connections and fiber cables before you connect or
reconnect components.
v
Ensure that cables are properly seated within the connector.
Kits are commercially available for cleaning and inspecting these connections. IBM
also offers services that will ensure optimal condition of the network.
Complete the following steps to install 16 Gbps SFP+ transceivers and cables.
1. Remove any protector plugs from the 16 Gbps SFP+ transceiver and the cable.
2. Ensure that both cable and transceiver are clean prior to installation.
3.
Position a cable so that the key (the ridge on one side of the cable connector) is
aligned with the slot in the transceiver. Insert the cable into the transceiver
until the latching mechanism clicks. Cables are keyed so that they can be
inserted in only one way. If a cable does not slide in easily, ensure that it is
correctly oriented.
Attention: Take care not to bend the SFP+ pull tab. Do not insert a cable
intended for an mSFP transceiver into a regular SFP+ transceiver. You may
damage the cable.
4. Transceivers are keyed so that they can only be inserted with the correct
orientation. Insert the cable/transceiver into the port, using the pull tab to help
push the transceiver into the port. If it does not slide in easily, ensure that it is
correctly oriented.
