DME rear view
The rear of the Block and File (Unified) VNX5500 platform 2U DME does not contain any
LEDs (Figure 36 on page 44). Only the Data Mover management module and the I/O
modules have LEDs. The following illustrations show the location of these LEDs while the
associated tables describe these LEDs.
Note: Figure 36 on page 44 is an example representation of the Block and File (Unified)
VNX5500 platform 2U DME rear view with two Data Movers (each Data Mover has one
management module, one four-port 8-Gb/s FC I/O module, thee two-port 1-Gb/s plus
two-port 1-Gb/s optical I/O modules, and one filler panel module).
