the physical expansion unit; the ID identifies which physical
unit corresponds to the system management status.
You can set the expansion unit ID to any value from
00–99. Each expansion unit attached to a Fibre Channel
controller must have a unique ID.
The base ID switch (x1) also sets the physical IDs of the
drives within the expansion unit. Some controllers might
require all drives on the FC loop to have a unique,
hard-assigned address. Refer to your controller
documentation to determine if unique, hard-assigned
addresses are required.
For each expansion unit ID, set the tray number for both
ESM boards to the same value. Set the tray number for
each pair of ESM boards to a unique value. The value
must be different from all other pairs of ESM boards
attached to the controller.
Attention
Each expansion unit tray number on both ESM boards
must match exactly. Otherwise, the expansion unit
might not function properly in the event of an ESM
board failure.
Installing the expansion unit in a rack:
The
EXP200 expansion unit requires 3U of EIA rack mounting
space. Before installing the expansion unit in a rack, it is
important that you do the following:
Review the rack documentation for safety and cabling
considerations. Ensure that your planned installation
is within the rack-enclosure guidelines for heat
generation, electrical requirements, air flow, and
mechanical loading.
Note
Because of the limited space in some racks, it
might be easier to connect and route cables
before you install the mounting brackets and
hardware devices.
Install the expansion unit in a maximum 35 degree C
environment.
To ensure proper air flow, position the unit in the rack
so that the air vents are not blocked. Usually 15 cm
(6 inches) of air space is sufficient.
To ensure the rack stability, load the rack starting
from the bottom.
If you install multiple components in the rack, do not
overload the power outlets.
Connect the expansion unit to a properly grounded
outlet.
