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.
Follow these instructions to install an SFP:
1. Ensure that both cable and transceiver are clean prior to installation.
2. Making sure that the bail (wire handle)
B
is in the unlocked position, place
the SFP in the correctly oriented position on the port, as shown in Figure 9 on
page 28
Note: Each SFP has a 10-pad gold-plated PCB-edge connector on the bottom.
The correct position to insert an SFP into the upper row of ports is with
the gold edge down. The correct position to insert an SFP into the lower
row of ports is with the gold edge up.
3. Slide the SFP into the port until you feel it click into place; then close the bail.
