Page 2 Gbps and E-Series 24 Gbps line cards may be mixed with no downspeed. The command reveals that the backplane power consumption is approximately 40 Watts followed by a detailed report of the installed modules. When used with the Cisco Catalyst Cisco Catalyst E Manual 88 pages. Web Vulnerability Scanner Free Download. When we completed our checkup, we decided it was time to install the card and finally power the R-E switch.
The heat sinks fins, covering the dual core CPU and other processors, are placed in a direction where the air from the fan tray can provide maximum cooling and heat dissipation:.
The Supervisor Engine 7L-E board is indeed impressive. In the photo below, we can see the WS-X main board with its chipsets, two of which are equipped with large heatsinks. Network Administrator Savvas Filippidis gets ready to install a line card. After ensuring the two module ejector levers one on each side were out and away from the faceplate, we gently lined it up with the two chassis slot guides of our slot and slowly pushed the line card inwards:.
Depending on how the switch is intended to be used, it can be populated fully with 48 Gigabit PoE ports, providing full PoE to all 5 line cards — a total of ports where each line card can draw a maximum of Watts. The whopping Watt power supplies were a considerable weight. To remove them, we had to loosen the captive installation screws two for each power supply and pull the power supply slowly outwards. Pulling out the power supply did not require much effort as it came out smoothly with the little force we used.
We took both power supplies out and took a picture of them to show both front and back side. At the back of each power supply, as expected, we found one long connector, split into three groups, the middle group containing pins which are barely visible in the picture:.
Going back to the chassis, all we found was the power supply connector where the middle pin sockets are easily seen. In total we counted an impressive 46 connection points between the power supply and chassis:.
After checking Cisco's site to find out more information, the explanation for the orange LEDs was that the Supervisor Engine was performing a ' System boot or a diagnostic test is in progress ', however it was not true as the system was fully booted and working.
A careful inspection showed that we had forgotten to switch on the second Watt power supply and the system was running off only one power supply. While we found no documentation to explain this behavior, we thought it would be worth mentioning for our readers and engineers preparing to install a series switch! Those who have had the luck to physically install and work on a Cisco Catalyst R or any Catalyst series switch would surely agree that it is a wonderful experience and impressive piece of equipment.
Examining the design and construction of the chassis, line cards and Supervisor Engines shows how much thought and work have gone into the product. Our next article covers the IOS upgrade of the Supervisor engine, health checkup, using the zero downtime IOS upgrade procedure — a necessary and extremely handy procedure that ensures the upgrade of the IOS Supervisor engines without any service interruption!

We carefully moved the R-E box to the datacenter and opened the top side of the box The upper area of the picture is where you'll find the two large cube slots for the power supplies. Below them, you can identify 6 out of the 7 slots waiting to be populated and give this monster unbelievable functionality! After opening the package and removing the plastic wrapping, we placed the switch on the floor so we could take a better look at it.
Because we couldn't wait any longer, we quickly opened one of two power supplies and inserted it into the designated slot. The power supplies installed were rated at Watts each - providing more than enough juice to power a significant number of IP Phones via the PoE cards installed later on.
The picture below shows both power supplies, one inserted into its slot, while the other was placed on top of the chassis with its connectors facing frontwards so you can get a glimpse of them. When inserted into its slot, the power supply's bottom connectors plug firmly into the chassis connectors and power up the Catalyst switch:. Turning on the power supplies for the first time made the datacenter's light dim instantantly as they began to draw power for the first time!
Interestingly enough, if you take a look at the power supply on top of the chassis, you'll notice three long white strips inside the power supply. These are actually three very large electrolytic capacitors - quite impressive! For those interested, the power supplies were made by Sony yes, they had a Sony sticker on them! As we mentioned in the beginning of this article, the powering engine of any series Catalyst switch is the Supervisor Engine.
The Supervisor engines occupy up to two slots on the R chassis, one of them used for redundancy in case the other fails. When working with two supervisor engines, the R is usually configured to automatically switch from one engine to the other without network interruptions, even for a VoIP network with active calls between ends.
Cisco currently has around 7 different Supervisor Engines, each with unique characteristics, designed for various levels of density and bandwidth requirements. Currently, the Supervisor Engine 6-E is the best performing engine available, providing Gbps bandwidth full duplex and million packets per second forwarding rate! Here's one of the supervisor engines in its original antistatic bag:.
After placing on my wrist the antistatic wrist-strap contained in the package and carefully unwrapping the supervisor engine, the green circuit-board with its black towers heatsinks is revealed.
You can easily see the 5 heatsinks, two of which are quite large and do an excellent job in keeping the processors cool:. At the back left side of the board, you can see the supervisor engine's connector which is equally impressive with pin connectors - 50 on each row! We took a picture from the back of the board to make sure the connector was clearly visible:. Just looking at the connector makes you imagine the number of signals that pass through it to give the R-E the performance rating it has!
Here is a close up of the engine's RAM module. The existing MB memory module can be removed and upgraded according to your requirements:. Moving to the front side of the Supervisor Engine, you can see the part number and description:.
These ports can come in handy when you're approaching your switch's full capacity. The impressive Supervisor Engine fits right into one of the two dedicated slots available on the R-E chassis. Also visible is the switch's backplane and black connectors awaiting the Supervisor Engine boards marked with red:.
We took another picture inside the chassis to make things as clear as possible:. Here you can see the backplane with the two Supervisor Engine connectors. The white coloured connectors just above and below the Supervisor Engines are used by the rest of the boards available to the R.
After inserting one of the Supervisor Engines and two power supplies, here is the result:. One detail well worth noticing is the colour coded bars on the left and right side of the Supervisor card. These colour codes exist to ensure engineers don't accidently try to insert a Supervisor card into an inappropriate slot. The R-E can accept upto two supervisor engines, therefore you have two slots dedicated to them, leaving 5 slots available. Cisco engineers have thought of everything on the R-E.
The cooling mechanisim is a good example of smart-thinking and intelligent engineering. With 7 cards installed on the system, pumping a generous amount of heat, the cooling had to be as effective as possible. Any heat captured between the cards could inadvertably lower the components' reliability and cause damage in the long term. This challenge was dealt with by placing a fan-tray right next to the cards in a vertical direction.
The fan-tray is not easily noticed when taking a quick glance, but the available handle on the front gives away that something is hidden in there. The picture taken on the left shows the eight fans placed on the fan-tray. These fans work full speed the moment you power the switch on, consuming Watts alone!
