Notes:
------
#EB2Y is switchable 1000W @ 100-127V or 1200W @ 200-240V
#EB2L/#EL1A is switchable 100-127V or 200-240V


#ESLA 800W is an Auto Ranging 127-240V AC Power Supply for EXP 12SX/EXP 24SX
 EXP 12SX Drawer FCs: #ESLL, #ELLL
 EXP 24SX Drawer FCs: #ESLS, #ELLS
The P/S has a standard IEC320-C14 inlet
2x Power Supplies are required


For Enterprise Servers (MT 9080/9119 MxE):
------------------------------------------
The System Node includes 4x Power Supplies (for 2+2 Redundant Power) under CCIN 51D2.

The P/S Units do not have FCs and are the same for both AC and DC Power.

These P/S Units use Power Chunnels to convey electrical power:
#EBAA AC Power Chunnels
#EBAD DC Power Chunnels

Each System Node requires 1x #EBAA OR 1x #EBAD (which inludes 4x Rear to Front Power Cords).

The Chunnel (Conduit) carries electrical power from the Rear of the System Node to the Hot Swap P/S Units located in the Front of the System Node (where they are more easily accessed for service).

The Power Supplies are rated as follows:
----------------------------------------
200-240V AC at 50/60Hz (+/- 3Hz) w/#EBAA AC Power Chunnels
192-400V DC                      w/#EBAD DC Power Chunnels


As noted, the Power Supply does not change (regardless of AC/DC input power), only the Chunnel components are different.

Important:
----------
This lack of FCs for the Enterprise Server Node Power Supply creates problems for PN look-up.  Therefore, although we include the PN for the Power Supply with the Chunnel FC's PNs, the P/S is not part of the Chunnel FC.


n+n Redundancy:
---------------
All Power 8 Systems use redundant Power Supplies.

Scale-Out Servers are normally 1+1.  Enterprise Servers are usually 2+2.

Systems are designed to still work with only 50% of the Required Power Supplies functioning.

However, all of the required P/S Units must present (regardless of whether or not they are functioning).  A failed P/S can be Hot-Swapped but must remain in the System until a replacement is available.
