Attention: To avoid damaging the LC-LC cable, make sure you press and hold
the lever to release the latches before you remove the cable from an LC-SC cable
adapter. Ensure that both levers are in the released position when removing the
cable. When removing the cable from the SFP module, make sure you do not grasp
the SFP module plastic tab.
1. On the end of the cable that connects into the LC connector end of the LC-SC
cable adapter, press down and hold the lever to release the latches. Figure 24
shows the location of the lever and latches.

2. Carefully pull on the connector to remove it. Make sure you grasp the connector
and not the cable when removing the LC-LC cable from the LC-SC cable
adapter.
3. Replace the protective caps on the cable ends.
FAStT700 Storage Server and drive enclosure cabling overview
The FAStT700 Storage Server supports two redundant drive loops. A redundant
drive loop consists of one or more drive enclosures connected to a controller using
two sets of Fibre Channel cables. If one data path fails, the controller uses the
other data path to maintain the connection to the drive group.
Figure 26 on page 26 shows a storage subsystem containing one storage server
and two redundant drive loops with four drive enclosures each. Each drive
enclosures group uses redundant drive loops to connect to the FAStT700 Storage
Server. Loop A and loop B make up one redundant pair of drive loops. Loop C and
loop D make up a second redundant pair.
