EX 4300

Description

This is an excellent modular switch and is the latest 1G data center grade switch.

It has modular uplinks {1 or 10G}

Everything is field replaceable.

It runs Virtual Chassis using a QSFP+ ports instead of some proprietary technology.

It can stack with the QFX family instead of the EX4500/4550

Redundant power

Reversible airflow.

Models and part numbers

These are the simple guys

24 port non PoE

24 port PoE

same thing with 48 ports.

These are the same but TAA,

TAA - Trade Agreement Act

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.

DC powered built into the switch.

so 48 port DC

48 port back to front {back being the PSU side front the port side}

same thing with TAA

SFP port switches

The above use SFP instead of RJ-45 ports.

They are used to aggregate older switches.

There is a DC model at the DC section above and a regular 32 port.

BACK to FRONT

these are the back to front, remember you usually use them when running the out of band network to manage the switches.

*** in general if you are really bored, you can buy a 24 port switch with reverse power supply and fan and then make your own

24 reversed airflow switch. #toomuchfreetime.

Uplinks

On the right bottom corner you have an uplink module.

The module can be

By default you get the blank faceplate.

Modular modules

The 32 port SFP models.

allow you the option of modularity.

They basically offer you 32 ports {2} and the options

of modularity and adding something to slot {1}

The slot {1} can hold

Layer 3 routing protocols support

Features Requiring a License on EX4300 Switches

To use the following features on the EX4300 switches, you must install an EFL:

• • Bidirectional Forwarding Detection (BFD)

  • Connectivity fault management (IEEE 802.1ag)

  • IGMP (Internet Group Management Protocol) version 1 (IGMPv1), IGMPv2, and IGMPv3

  • Multicast Source Discovery Protocol (MSDP)

  • OSPFv2/v3

  • Protocol Independent Multicast (PIM) dense mode, PIM source-specific mode, PIM sparse mode

  • Real-time perfomance monitoring (RPM)

  • RIPng (RIP next generation)

  • Unicast reverse-path forwarding (RPF)

  • Virtual Router

  • Virtual Router Redundancy Protocol (VRRP)

Each of these switches can be upgraded to support Layer 3 routing protocols {except for BGP}

Each of these switches can be upgraded to support Layer 3.

Features Requiring a AFL License on EX4300 Switches

To use the following features on EX4300 switches, you must install an AFL:

• • Border Gateway Protocol (BGP) and multiprotocol BGP (MBGP)

  • Intermediate System-to-Intermediate System (IS-IS)

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.

the 1100W uses C15

C15 has a groove.

By the way 48 port Poe is the only 1100W

Mounting the switch.

Wall mounting it

I have no idea what the baffle kit is for

I will have to reach out to Juniper for this.

I guess it has something to do with airflow.

or you could say I am baffled : )

Desktop.

2 Post or 4 post using 2 of the posts.

This kit is included when you buy a switch, if you lost it you can order the above.

4 post attached to all 4 posts.

32 port

48 port

EX4300 - 32 port SFP

EX4300 all other

Yes, the 32 port switch only has 2 QSFP+ ports.

I have no idea why, don't ask me.

Juniper must hire professional obscurefercers. {people who obscure stuff}

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 or secondary power supplies

Spare fans for cold spare storage.

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.

If and only if your client has 10 units or more.

He can get a site license.

For example if you are a school, where you mount these under the desks.

You can save a lot of money and get a site license.

All the units at the site must have this applied to them.

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