ALCATEL-LUCENT ENTERPRISE DATA SHEET

Combo ports are ports individually

congurable to be 10/100/1000 Base-T or

1000Base-X, which spuport SFP transceiv-

ers for short, long and very long distances.

Gigabit ber interfaces on the OmniSwitch

6855-U10 and OmniSwitch 6855-U24X

models support Gigabit SFP or 100Base-X

SFP optical transceivers. See the full list of

supported transceivers at the end of the

data sheet.

POWER SUPPLIES

OmniSwitch 6855 models support redun-

dant, hot-swappable AC, DC or PoE power

supplies. The primary and the backup

power supply units are external, allowing

for easier maintenance and replacement.

There is no interruption of service when

a new power supply is installed or an old

one replaced.

Power supplies for OmniSwitch

6855-14, OmniSwitch 6855-P14

and OmniSwitch 6855-u10

The power supplies for the half rack mod-

els come in the form of a power brick in

either AC or DC variant. A separate power

brick provides PoE power and is available

for purchase when PoE is required.

Power supplies for

OmniSwitch 6855-24 and

OmniSwitch 6855-U24X

The primary and the backup power

supplies for the 24 port models are

modular and connect to the rear of the

unit. A power shelf provided with the unit

can slide into the rear of the switch and is

used to hold two power supplies.

Any power supply can be remotely

connected using a cable, which enables

rack mounting using the mounting ears

provided with the unit. This feature allows

for space-sensitive installations requiring

reduced depth (for example, in a wall-

mounted cabinet).

Indicators

• Per-port LEDs: link/activity/PoE

• System LEDs: OK (switch HW/SW status)

• PS1/PS2: primary and/or redundant power

supply status

• 7-segment LED on OS6855-U24X

indicating the operational mode

and stack number
