modules in the same positions on the new ESM.
6. Remove the SFP modules and the fibre-channel cables from the failed ESM.
Attention: Be careful not to bend the fibre-channel cables at a sharp angle or
pinch them with objects. This can decrease the performance or cause data loss.
7. Squeeze the ESM latch. The ESM latch is a coral colored tab on the lever.
8. While squeezing the latch, pull the lever open 90° (so that the lever is
horizontal). Pull the lever away from the chassis to remove the ESM from the
EXP395 midplane, as shown in Figure 37.
Note: The lever rotates upward or downward 90°, depending on whether the
ESM you are removing is in the right or left ESM bay.
