Installing transceivers and attaching cables
The following two sets of steps cover the installation of transceivers and cables for
most SFPs and for QSFPs.
Attention:
Use only transceivers that are supported for this product. Only
transceivers purchased from IBM are supported. The use of transceivers that are
not supported may cause data loss or cause the product to malfunction. For a
listing of transceivers compatible with this product:
v
Go to the IBM Support Portal http://www.ibm.com/supportportal.
v
In the
Search
field, enter
b-type supported transceiver
, and then click the
appropriate link.
v
Alternatively, use this direct link: http://www-01.ibm.com/support/
docview.wss?uid=ssg1S1004421.
Follow the first set of steps to install SFP+s and mSFPs (FC8-64 port blade only)
and cables in the SAN768B-2 (for more details, see “Removing and installing
transceivers” on page 108). Follow the second set of steps to install the QSFP
transceivers and cables in the FC16-64 and core blades for inter-chassis link
connections (see “Removing and replacing inter-chassis link (QSFP) cables” on
page 113 for more details,)
Attention:
mSFP transceivers are compatible only with the FC8-64 port blade.
While they will fit in other blades, this configuration is unsupported and will
generate an error.
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.
The ports are color-coded to indicate which can be used in the same port group for
trunking (trunking port groups can be up to eight ports). The ports and cables
used in trunking groups must meet specific requirements. Refer to the
Fabric OS
Administrator’s Guide
for more information.
