Power Distribution Unit (Pdu); Fan Modules; Buttons And Connectors - Cisco UCS 5108 Installation Manual

Buttons
Buttons
There are no buttons on the IOM.
Connectors
There are four QSFP, 40-Gigabit uplink ports on the front of the IOM. The Ethernet management port and
console connector use an HDMI connector that connects to a special Y dongle to expose the 10/100 RJ45
port and console connections.

Power Distribution Unit (PDU)

The AC PDU (N01-UAC1) provides load balancing between the installed power supplies, as well as distributing
power to the other chassis components. DC versions of the chassis use a different PDU with appropriate
connectors. The PDU is not field-serviceable, and converting an AC chassis to a DC chassis by swapping the
PDU is not supported, as the PDU is not separately orderable.
LEDs
No LEDs are on the PDU.
Buttons
No buttons are on the PDU.
Connectors
The AC version of the PDU has four power connectors rated for 15.5 A, 200-240V @ 50-60 Hz. Only use
power cords that are certified by the relevant country safety authority or that are installed by a licensed or
certified electrician in accordance with the relevant electrical codes. All connectors, plugs, receptacles, and
cables must be rated to at least the amperage of inlet connector on the PSU or be independently fused in
accordance with the relevant electrical code. See for more information about the supported power cords. See
Supported AC Power Cords and Plugs, on page 81
The DC version of the PDU has eight dual-post lug power connections, four positive and four negative. A
single dual-post lug grounding connection is also provided. The HDVC version of the PDU uses one Andersen
SAF-D-GRID(R) connector per power supply.

Fan Modules

The chassis can accept up to eight fan modules (N20-FAN5). A chassis must have filler plates in place if no
fan will be installed in a slot for an extended period.
LEDs
There is one LED indication of the fan module's operational state. See
details.

Buttons and Connectors

No buttons or connectors are on a fan module.
