Installing a 2 x10-Gigabit Ethernet Module
Follow these procedures when installing a 10-Gigabit Ethernet Module.
1. Power off the NetIron CES or NetIron CER 2000 Series device.
2. Use a #2 Phillips-head screwdriver to remove the blank faceplate or old module from the front
panel.
3. Install the 10-Gigabit module in the chassis.
4. Use a #2 Phillips-head screwdriver to fasten the screws on the 2 x10-Gigabit module. Affix the
screws loosely at first, then tighten them once you are sure the board is properly positioned.
Replacing the NetIron CES and the NetIron CER Series fan tray
The NetIron Series devices cooling fans use pull configuration to move the air from the front to the
back of the device.
The fans in the NetIron Series devices include six four-speed fans that operate at low speed,
medium speed, medium-high speed, and high speed based on the ambient temperature and
configured or default temperature thresholds. All fans operate simultaneously at the same speed.
If a single fan fails within the assembly, the fan tray should be replaced. The fan tray is hot
swappable.
The system uses a default or configured temperature threshold associated with it to determine at
which speed the fan should operate. If desired, you can change the settings of the temperature
thresholds associated with fan speed switches.
If a NetIron CES and the NetIron CER Series device remains operational during a fan tray
replacement, the procedure must be completed within 30 seconds.
NOTE
Fan trays are hot swappable. Hot swapping fan trays should be done within 30 seconds so the unit
will continue to function correctly without any fans. However, Brocade recommends that you
disconnect the power supply from AC or DC power before installing or removing the fan tray.
To replace the NetIron CES 2000 Series fan tray, follow these steps.
1. Power down and unplug the chassis.
2. Unscrew the two screws that secure the fan tray to the chassis.
