Power subsystem

The power subsystem is located on the system board. The BL860c i2 and i4 Server
Blades receive 12 volts directly from the enclosure. The voltage is immediately passed
through an E-fuse circuit, which will immediately cut power to the blade if a short
circuit fault or over current condition is detected. The E-fuse can also be intentionally
power cycled through the manageability subsystem. The 12 volts is distributed to
various points on the blade and is converted to lower voltages through power
converters for use by integrated circuits and loads on the blade.

ESD handling information

CAUTION:
Acceptable ESD wrist straps include:
The wrist strap that is included in the ESD kit with circuit checker (part number
9300-1609).
The wrist strap that is included in the ESD kit without circuit checker (part number
9300-1608).
If the above options are unavailable, the throw away (one use only) strap that ships
with some Hewlett Packard Enterprise memory products can also be used, with
increased risk of electrostatic damage.
When removing and replacing server components, use care to prevent injury and
equipment damage. Many assemblies are sensitive to damage by electrostatic
discharge.
Wear an ESD wrist strap when handling internal server components.
