Attention: mSFP optical transceivers should not be inserted into ports intended
for SFP+ transceivers. They will be faulted on power-up.
To replace an mSFP transceiver, complete the following steps. Due to high port and
cable density, it is recommended that the optical cable be either removed from or
inserted into the mSFP while the transceiver is out of the switch or blade.
Removing an mSFP transceiver
Attention: The pull tabs are not designed to be bent. Doing so may result in
damage to the pull tab.

To remove an mSFP transceiver, complete the following steps.
1. Grasp the pull tab

firmly and pull the unit (including the cable) out of the
port.
2.
Remove the cable from the transceiver.
3. Set the transceiver on a static-free surface, such as a grounding pad.
Installing an mSFP transceiver
To install an mSFP transceiver, complete the following steps.
1. Insert the cable into the new transceiver until the latching mechanism clicks.
2. Position the optical transceiver so that the key is oriented correctly to the port.
Insert the transceiver into the port until it is firmly seated and the latching
mechanism clicks.
Transceivers are keyed so that they can only be inserted with the correct
orientation. If a transceiver does not slide in easily, ensure that it is correctly
oriented.
Removing and replacing inter-chassis link (QSFP) cables
Use this procedure to remove and install QSEP cables.
Note: ICL ports can be used only with an ICL license. After the addition or
removal of a license, the license enforcement is performed on the ICL ports
only when the
portDisable and portEnable commands are issued on the
ports. An ICL license must be installed on all systems forming the ICL
connection. The systems can be any combination of up to five neighboring
SAN384B-2 and SAN768B-2 chassis. An off-the-shelf QSFP cable up to 50
meters long can be used as an ICL cable.
Attention: If QSFP cables are not in use, make sure the rubber gaskets are in the
QSFP transceivers.
