Removing an LC-LC Fibre Channel cable
Complete the following steps to remove an LC-LC Fibre Channel cable:
Attention: To avoid damaging the LC-LC cable or SFP module, make sure that
you observe the following precautions:
v Press and hold the lever to release the latches before you remove the cable from
the SFP module.
v Make sure that the levers are in the released position when you remove the
cable.
v Do not grasp the SFP module plastic tab when you remove the cable.
1. On the end of the LC-LC cable that connects into the SFP module or host bus
adapter, press down and hold the lever to release the latches, as shown in
Figure 33.

2. While pressing down the cable lever, carefully pull on the connector to remove
the cable from the SFP module, as shown in Figure 34.
3. Replace the protective caps on the cable ends.
4. Replace the protective cap on the SFP module.
Connecting storage expansion enclosures to the DS5020
Attention: Before you turn on the power to the DS5020 storage subsystem, it
must be populated with at least two E-DDMs. If at least two E-DDMs are not
installed in the DS5020, an insufficient load to the enclosure power supplies might
cause them to intermittently appear as failed, falsely indicating the power supplies
are bad. All of the E-DDMs in the DS5020 storage subsystem and the connected
storage expansion enclosure or enclosures must contain no prior configuration data.
