Symantec Storage Shelf hardware removal and replacement
I/O modules 1 and 2
9. Secure, but do not strip or over-torque the screws.
TBD Never leave a power supply module bay empty. Proper air cooling
through the entire device depends on having both power supply module bays
installed with the proper components.
I/O modules 1 and 2
There are two I/O modules in the Symantec Storage Shelf; one primary and one
secondary module. Both modules are located in the rear of the storage shelf. I/O
module #1 is on the left side of the device. I/O module #2 is on the right side of the
device.
Symantec Storage Shelf I/O modules 1 and 2
Each I/O module is hot-swappable. It is not necessary to power down the storage
shelf. To remove and replace an I/O module:
1.
Loosen the release latch of the I/O module (#1 or #2) that you wish to
remove.
2. Pull the sides of the module toward you, so that it slides out of its bay.
3. Obtain a new I/O module and place it into the empty bay.
4. Slide the module forward until it snaps into place.
5. Secure the release latch.
