Installation Guide v1.0 - 9 -

GbE/PSE:

· May be used as a network connection for an out of band management port. Some

models support the use of Power Devices on this port to power a PoE camera or

similar device for monitoring site conditions.

· Interface is a GbE copper port with an RJ-45 connector. Should remain capped

when not in use.

SYNCIN:

· Can be used to supply a 1PPS synchronization pulse if neither GPS nor IEEE

1588 are available. This is generally used for testing purposes, and the system

must be configured to accept this signal. Please contact Axxcelera Support if

more information is required.

· This port should remain capped when not in use.

CONSOLE:

· Used to console access to the BBU. This is not a customer supported interface

that is used by authorized Axxcelera service engineers only.

· Interface uses a mini USB connector, and should be capped when not in use.

POWERIN:

· The BBU power port is only available when not integrated with an RRH;

otherwise, the power port of the RRH will be used for both sections of the

integrated unit.

· Nominal input voltage is -48VDC. Operable range is -40..-60VDC.

· Uses a supplied, multi-pin circular connector.

UPLINK1:

· Used as the network connection (LTE S1 interface).

· Accepts a field serviceable optical SFP module.

UPLINK2:

· This port may be used as a redundant connection to the PDN or for stacking

multiple BBUs on to the same backhaul pipe. Should be capped if not in use.

CPRI-1 through CPRI-3:

· These CPRI ports are used to connect to one or more remote radio head units.

Connections can be made in a star or daisy-chain topology. Ports support CPRI

v4.1 with a line rate up to 6144 MBps using field upgradable SFP modules for

single- or multi-mode fiber connections.

· Interface uses an optical SFP module and should be capped when not in use.
