Installing and Removing a Power Supply
Power Supply Addition or IOM Removal
When a power supply is added or an IOM module is removed, the G3 responds to the increase in available power by:
1.Detecting the power supply addition and recalculating available power (adding capacity of the new power supply or accounting for less load with removal of an IOM module).
2.Subtracting the power capacity for its base system and all installed modules from available power.
3.Distributing remaining power equally across installed PoE controllers by reprogramming maximum power in each controller.
Installing a Power Supply
Power supplies are installed in either of the two slots located at the back of the chassis, as shown in Figure 2‐2. If you intend to install only a single power supply, it can be installed in either of the slots, although the PWR1 slot is left open for your convenience.
To install one or both power supplies in the G‐Series switch, refer to the following figures and proceed as follows:
1.With an antistatic wrist strap attached to your wrist, unpack the power supply by removing it from its shipping box and stripping the packing material. (Save the shipping box and materials in the event the unit must be reshipped.)
2.Remove the power supply from its protective wrapping.
3.Examine the power supply carefully, checking for damage. If any damage is noted, do not install the power supply. Contact Enterasys Networks for instructions.
4.If necessary, remove the coverplate from its slot by loosening its captive screws. Retain the coverplate for future use.
5.Holding the power supply by its handle, position it with the AC inlet to the left and align it with the slot opening.
Caution: Forcing a misaligned power supply into place can damage the power supply or chassis backplane.
Precaución: Colocar de manera forzada una fuente de poder o no colocarla bien alineada podría dañarla y/o maltratar el panel posterior del chasis.
6.With the power supply properly inserted into the opening, carefully slide the module until it connects to the backplane, as shown in Figure 2‐2. The module’s handle should be nearly flush with the back of the G‐Series switch. If significant resistance is encountered before the power supply is seated, remove and reinsert it. Do not force the module into place.
