EX-4550

Description

This is an excellent modular switch and is a 10G data center grade switch.

It has modular uplinks {1 or 10G}

Everything is field replaceable.

It runs Virtual Chassis using either the proprietary stacking ports or QSFP+ ports.

Redundant power

Reversible airflow.

Models and part numbers

Simple enough,

32 ports of SFP+

32 ports of RJ-45 copper that run 1000/10000 speeds.

AFO air flow out. The air flows OUT of the power supply.

Since these are datacenter switches, some clients might want the airflow reversed.

In that case you will be selling the AFI air flow in.

Notice the air is flowing IN to the power supply, so AFI

DC powered.

The same can be done with a DC power supply.

When you sell to the USA government in a contract over the sum of $194,000 the products must comply with TAA. This means they are

mostly produced or modified in the USA or a country that has a reciprocal trade agreement with the USA.

{China and most notable electronic makers are absent }

So basically, the parts are the same parts as a regular EX3300 but it is assembled in the USA, this will add 20% or less to the cost of each item.

Notice, when selling to the government of the USA you MUST use TAA.

Uplinks and Virtual Chassis

On the left you have a slot for a module.

These power cords are pretty simple.

They are C13 on one side.

the other side will depend on the country.

If you need a different length or if you come from a country not on this list.

You can use a third party cable. We can provide this.

*By default the switch comes with 1 cable for the country it is being sold to.

Mounting the switch.

Optics

Supported SFPs are

I've arranged this by the chances of someone ordering them

1 Gbps optics.

T is copper

SX is multimode

For singlemode ask for the distance to verify which one.

100 speed optics also called FE

These are mainly for backward compatibility to very old devices.

CWDM optics

CWDM allows you to use eight active wavelengths. So basically 8 people can send on the same fiber cable.

Each of the above works in one wavelength and the other side must have the same optic wavelength.

Single Strand

Single strand allows a client to get 1 Gbps of traffic on a single fiber cable.

So for example if the client has 1 Fiber cable

He can double the throughput he can run on it by using single strand technology.

So instead of 1Gbps of traffic, he can run 2Gbps. Blue will be receive and red will be send.

Anyway, I doubt many people are smart enough to use this and both sides must support the SFP technology.

QSFP+ cables

There is a USB port.

The USB port supports 1G , 2G ,4G

Odd things.

Apparently there is a license to enable MACSEC

The Mini USB is another console port and requires the

Spare fans for cold spare storage.

Stacking cables

*EX 4550 doesn't include a cable, you must order one .

Support options are.

Next Day Ship, this applies only to (AVAILABLE FOR BRAZIL, RUSSIA, INDIA, AND CHINA ONLY)

and means that they will ship it the next day, not when it arrives.

The support changes by country.

The Juniper options of support are listed below in this slide.
