Expansion units
You can connect up to two expansion units:
• 16-port expansion unit
• 24-port expansion unit
There are two hardware versions of the 16-port
expansion unit. On Release 4.0 versions and later, the
ports are located on the front panel starting from the left
side of unit. On previous hardware versions of the 16-port
expansion units the ports start from the right side of the
unit.
The 24-port expansion unit and the Release 4.0 version
(and later) of the 16-port expansion unit monitors the
power output to the ports. If the expansion unit power
supply approaches its maximum output, or if the
expansion unit fan fails, all the ports on the expansion
unit will be powered down. See for Table 7 on page 171
for details.
