BTI7801 Power
The BTI7801 is powered by the same field-replaceable power entry modules found on
the BTI7802. Both AC and DC versions are supported.
NOTE: If your chassis has redundant PEMs, you will be able to replace a failed
PEM while the redundant PEM continues to power the chassis. For more
information, see
“BTI7801 Field-Replaceable Units (FRUs)” on page 199 .
BTI7801 Power Distribution Plan
The BTI7801 supports redundant power feeds, A and B, that allow the chassis to survive
failure in any one feed. External power is applied to the Power Entry Modules, which, in
turn, power the chassis. Each PEM can power the whole chassis.
BTI7801 DC PEM
The BTI7801 chassis can be powered by up to two convection-cooled 1-Slot/2-Slot
Chassis DC Power Entry Modules (BT8A78PEM1-DC). This is the same PEM that powers
the BTI7802. See
“BTI7802 DC PEM” on page 48 for more information.
BTI7801 AC PEM
The BTI7801 chassis can be powered by up to two fan-cooled 1-Slot/2-Slot Chassis AC
Power Entry Modules (BT8A78PEM1-AC). This is the same PEM that powers the BTI7802.
See
“BTI7802 AC PEM” on page 50 for more information.
