Chapter 2: MediaDirector 2252B/2251B component replacement
What to do next
Follow instructions in the
Spectrum System Installation Guide
for reconnecting the MediaDirector to your
Spectrum system and powering on the device.
Installing the SFP transceiver
The SFP transceiver is designed to fit firmly in the SFP cage. A reasonable amount of friction is normal,
especially with new I/O modules.
1. Remove the protective caps from the SFP cage, SFP transceiver, and fiber optic cable, and then store
the caps in a safe place for later use.
2. Position the replacement SFP transceiver such that the label is on the bottom.
CAUTION:
You may damage the connector pins on the back of the transceiver if it is
not oriented correctly during installation.
3. Raise the lever on the front of the SFP transceiver to the up position, and then slide the transceiver
straight into the slot until the locking latch engages the transceiver.
CAUTION:
To avoid damage to the chassis assembly, do not force the transceiver to
slide.
4. Once the transceiver is seated, lower the lever to the down position.
5. Orient the fiber optic cable so that the latch is on the bottom, and then connect it to the SFP
transceiver.
You will hear an audible click when the cable is secure.
Replacing an SFP transceiver
Use only Harmonic-supplied optical SFP transceivers in the dual-port optical 10 GbE IOM in the
MediaDirector.
DANGER:
Observe all conventional ESD precautions when handling Spectrum devices
and components.
Removing the SFP transceiver
If replacing an individual SFP transceiver, you may do so while the system is powered on.
CAUTION:
When removing and installing SFP transceivers and fiber optic cables,
damage can occur which results in the loss of loop noise immunity and possibly in the
complete failure of the loop. To avoid damage, be sure to follow the removal and installation
procedures in this section.
NOTE:
SFP transceivers are dust-sensitive. Always keep protective caps installed when a
fiber optic cable is unplugged, or when storing the SFP transceiver.
NOTE:
SFP ports are numbered 0 and 1, from left to right.
