The dashed lines in Figure 33 show how to add a new EXP395 to an existing
DS3950 configuration with EXP395s. To add the new EXP395 shown in Figure 33,
perform the following steps:
1.
Unpack and install the EXP395 drive expansion enclosure. Do not insert any
drive FRUs into the enclosure drive slots.
2. Verify that the Link Rate speed is at the correct setting. You cannot add storage
expansion enclosures with different Link Rate speed settings in the same
redundant drive loop.
3. Power on the EXP395 storage expansion enclosure.
4. Make the fibre-channel connection marked
1
in Figure 33 (drive loop A) by
connecting port 1A of the existing EXP395 to port 1B of the new EXP395 . Then
verify that it is recognized by the DS Storage Manager software GUI.
5. Move the existing fibre-channel connection marked
2
in Figure 33 from the
existing EXP395 enclosure ESM port IB to the new EXP395 enclosure ESM port
1B.
6.
Make the fibre-channel connection marked
3
in Figure 33 (drive loop B) by
connecting port 1A of the new EXP395 to port 1B of the existing EXP395.
