Cisco 3650 Vs. 3850 Catalyst Switches

Cisco Catalyst 3650 and 3850 series switches are enterprise class stackable switches. Cisco Catalyst 3650 series was unveiled in 2013 which designed to converge wired and wireless networking. Just in the same year, Cisco launched its first flagship Catalyst 3850 series switches . That provide a converged wired and wireless platform as well. With they have many things in common, many people confused about them and found it hard to decide which one to buy. This article would introduce Cisco 3650 and 3850 series switch as well as their main differences.

Cisco Catalyst 3650 Series Switch

There are 21 Cisco 3650 Series Switch models in total. All Cisco Catalyst 3650 Series Switches have fixed, built-in uplink ports. The Catalyst 3650 features line rate 24 and 48 Gigabit Ethernet ports and an integrated wireless controller. It can be stacked in groups of nine switches for support of up to 25 access points and 1,000 clients at 40Gbps. The uplink ports of all switch models can be divided into the following five types:

  • Four Gigabit Ethernet with Small Form-Factor Pluggable (SFP)
  • Two 10 Gigabit Ethernet with SFP+ and two 10 Gigabit Ethernet with SFP or four Gigabit Ethernet with SFP
  • Four 10 Gigabit Ethernet with SFP+ or four Gigabit Ethernet with SFP
  • Eight 10 Gigabit Ethernet with SFP+ or eight Gigabit Ethernet with SFP
  • Two 40 Gigabit Ethernet with QSFP+

Figure2: Cisco 3850 PoE+ Switch

  • High compatibility. The 3850 switches support a variety of optical modules and connectors, therefore allowing many deployment options.
  • Enhanced security. It comes with native TrustSec functionality such as Security Group Tag (SGT) so that you have it enabled everywhere—from access to aggregation. Also, fiber connections provide strong physical security.
Differences
—Flexibility

The flexibility of the 3850s is greater than the 3650s, because they are stacking and optional stacking switches respectively. The 3850s can do power stacking, that is an exclusive feature compared to the 3650s. Stacking is built in, and the short stacking cables are included. Larger stacks might require the longer stacking cables, that is a potential downside.

3650s can do stacking as well, but you need to buy the modules separately (and they are like $1,000 a pop list price), which adds up quickly.

—Power

The 3850s is the more powerful device than the 3650s, which featured as the great horsepower. Besides, as we mentioned before, the 3850s can do power stacking while the 3650s cannot.

—Capacity

Compared with the 3650s series switches, the 3850s series switches have higher capacity. The maximum switching capacity of the 3850s switches can arrive at 1280 Gbps on 48-port 10 Gigabit Ethernet SFP+ model while the 3650s switches at 472 Gbps on 48-port Multigigabit models.

AgilePorts—An Unique Design for Connection on Arista 7150S-64 Switch

In order to meet the requirements of demanding environments such as ultra low latency financial ECNs, HPC clusters and cloud data centers, Arista launched a series of switch—Asita 7150S, including 7150S-24, 7510S-52 and 7510S-64. The Arista 7150S series represents the industry’s leading ultra low latency 1RU 1/10/40GbE layer 2/3/4 wire speed switch family. As one member of the Arista 7150S family, Arista 7150S-64 switch has both SFP+ and QSFP+ ports while the another two haven’t QSFP+ ports. This article would provide the basic information about Arista 7150S-64 switch and its network migration with Agile ports.

An overview on AgilePorts

The most distinctive feature of Arista 7150S switch is the design of AgilePorts on the switch which enables flexible deployment. AgilePorts deliver complete flexibility in connectivity—each SFP+ interface is capable of supporting 100M-10G over a variety of media, including DWDM with distances up to 80 km. The AgilePorts feature also enables groups of adjacent SFP+ ports to be configured for 40Gb operation using 10G transceivers and cables providing maximum port flexibility and a seamless migration from 10Gb to 40Gb.

Information About Arista 7150S-64

The Arista 7150S-64 has 48 SFP+ and 4 QSFP+ ports, you can see the detailed information in the below table. Different from the other two 7150S switches, 7150S-64 has the largest number port and it is the only one has QSFP+ ports. The SFP+ ports can support 1G and 10G operation and also 100Mb support with 100/1000-TX transceivers. On this 7150S-64 switch with QSFP+ ports, you can split the 40G interfaces into 4×10G. The 7150S-64 switch can provide 16×40G interfaces including 4 QSFP+ ports and 12×40G ports (48 SFP+ ports grouped into 12×40G) (see figure1).

For the QSFP+ ports, there is a wide range of choices as well, including 40GBASE-CR4, 40GBASE-SR4, 40G-PLRL4, 40GBASE-LR4 and etc. The distances can be supported from 100 m over OM3 to 10 km over single-mode fiber on the 7150S-64 switch.

Two Different Connection Solutions

We would mainly compare the common practice of connection with connection with AgilePorts to highlight the key distinction of connection with AgilePorts.

General Connection From 10G to 40G Network

For any network migration, optical transceivers play an essential role. So does the 10G to 40G network migration—you must take 40G QSFP+ transceiver into consideration. If you use the general switches to migrate 10G to 40G network, you can take the following connection solution as a reference. Just as we see in the below picture, an MPO/MTP LGX cassette connects four 10G SFP+ links. And then a Type-B female MPO/MTP trunk cable is used to connect the cassette and 40G QSFP+ Transceiver.

40G-solutions

Figure2: 10G to 40G solution (1)

Connection With AgilePorts on Arista 7150S-64

Like we described before, the Arista 7150S switch’s AgilePosts is designed to address device and cabling life cycles, you can upgrade from 10GbE to 40GbE only with just 10G SFP+ transceivers and cables. It provides maximum port flexibility and a seamless migration. Under this situation, 40G QSFP transceiver is unnecessary. 40G connection is achieved by connecting four 10GBASE-SR SFP+ transceivers with LC duplex fiber patch cables. In this way, time and space are saved through this kind of connection.

40G-solutions-2

Figure3: 10G to 40G solution (2)

Conclusion

The Arista 7150S-64 is a 10/40G Ethernet switch, the distinctive design of AgilePorts on the switch plays a prominent role on the network data rate migration from 10G to 40G. If you need 40G optical transceiver for 10G to 40G migration, FS.COM is a good choice. Recently, we have a slump on 40G QSFP SR4 and 100G QSFP28 SR4, buy a 40G QSFP SR4 transceiver only needs $49 at FS.COM.

The proper connectivity procedures and some installation notes are very essential for connection between DAC cable and the switch. The detailed information are just below.

The connectivity steps:

1. If the QSFP+ DAC cable connector is covered with a rubber safety cap, remove the cap. Save the cap.
2. Check the port on the switch and make sure the right connectivity. If you choose 40G QSFP+ to QSFP+ DAC cable for connectivity, please make sure that is a 40G port.
3. Insert the cable connector into the switch port.

DAC cable to switch-connection

Figure1: Connecting a DAC cable to a switch

4. Secure the cables so that they do not support their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.

Warnings and Cautions

1. Before you begin connecting the QSFP+ DAC cables to the switch, ensure that you have taken the necessary precautions for safe handling of lasers.
2. Do not bend the QSFP+ DAC cables beyond their minimum bend radius. An arc smaller than a few inches in diameter can damage the cables and cause problems that are difficult to diagnose.
3. Do not let the DAC cables hang free from the connector.
4. Do not allow fastened loops of cables to dangle, which stress the cables at the fastening point.

Installing a QSFP+ transceiver in Arista 7250QX-64

There are many QSFP+ transceiver types supporting Arista 7250QX-64, including QSFP-40G-SR4, QSFP-40G-XSR4, QSFP-40G-PLRL4, QSFP-40G-LRL4, QSFP-40G-PLR4, QSFP-40G-LR4, and QSFP-40G-ER4. Before you begin installing one QSFP+ transceiver in an Arista 7250QX-64 switch, ensure that you have a rubber safety cap available to cover the transceiver. And to prevent electrostatic discharge (ESD) damage to the transceiver, do not touch the connector pins at the ends the transceiver. Figure 2 shows how to install a QSFP+ transceiver.

Optical transceiver-switch connection

Figure 2: installing a QSFP+ transceiver in a switch

Installation steps:

1. Remove the transceiver from its bag.
2. Check to see whether the transceiver is covered with a rubber safety cap. If it is not, cover the transceiver with a rubber safety cap.
Warning: Do not leave a QSFP+ transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.
3. If the port in which you want to install the transceiver is covered with a dust cover, remove the dust cover and save it in case you need to cover the port later. If you are hot-swapping a transceiver, wait for at least 10 seconds after removing the transceiver from the port before installing a new transceiver.
4. Using both hands, carefully place the transceiver in the empty port. The connectors must face the switch chassis.
Caution: Before you slide the transceiver into the port, ensure that the transceiver us aligned correctly. Misalignment might cause the pins to bend, making the transceiver unusable.
5. Slide the transceiver in gently until it is fully seated.
6. Remove the rubber safety cap when you are ready to connect the cable to the transceiver.

Summary

From the above passage, we may observe that it is not difficult to connect QSFP+ DAC cables or QSFP+ transceiver to the Arista 7250QX-64 switch. Whether you are using DAC cables or QSFP+ transceivers to make connectivity, please remember that do not look directly into a optical transceiver or into the ends of the DAC cables, the laser light may damage your eyes.
