Various of types and necessary warranty about Cisco switch
Cisco switches come in many different models. This is why it is important that you find out all about the pros and cons of the many different types of switches that are available to you. The tough part is finding the right switch for you, because there are a lot of different models for you to go through. Because of this, finding the perfect Cisco switch can be a long and arduous process. However, by a simple process of reading about the different type of switches and the benefits and disadvantages of them, you are then able to find the right one for you.
Let’s first take a look at the Cisco Catalyst 2960 Series. The Cisco Catalyst 2960 Series with PoE allows connectivity to Ethernet powered devices including Cisco IP phones, wireless access points and video cameras. The Cisco Catalyst 2960-24PC-L can support 24 simultaneous full-powered PoE ports at 15.4W. The Cisco Catalyst 2960-24LT-L has 24 10/100 Mbps ports with 8 simultaneous full-powered PoE ports at 15.4W.
Cisco Catalyst 2960 Series Switches with LAN Base software are a family of fixed-configuration, standalone intelligent Ethernet devices with Power Over Ethernet (PoE) or non-PoE configurations that provide desktop Fast Ethernet and Gigabit Ethernet connectivity, enabling enhanced LAN services for entry-level enterprise, midmarket, and branch office networks.
The Cisco Catalyst 2960-8TT-L has eight 10/100 ports with one 10/100/1000 PoE input port. This switch does not need a power supply and receives power through the uplink from an upstream PoE switch, providing deployment flexibility and availability. It is ideal for wiring and space-constraint applications. The power adaptor (PWR-A=) and power cord are optional and may be purchased separately.
PoE eliminates the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cable and circuits that would otherwise be necessary in IP phone and WLAN deployments. PoE switches also eliminate the need for power injectors and PoE mid-spans for powering IP devices.
The Cisco Catalyst 2960-24PC-L Switch with Power over Ethernet (PoE) is a new member of the Cisco Catalyst 2960 Series. The Cisco Catalyst 2960 Series also offers models with LAN Lite software that provide desktop Fast Ethernet connectivity for wiring closet and small branch-office networks to provide basic LAN services. The LAN Lite Cisco IOS Software provides entry-level security, quality of service (QoS), and availability capabilities while lowering the network’s total cost of ownership.
A Cisco switch is not a God particle. It is just as vulnerable as other switches. The recent (late-2011) Blackberry server crash has mainly been attributed to a failed Cisco switch that was situated in Blackberry’s core network, which handled dynamic and overcrowded databases in real time. So, the lesson is here is that even the awe-inspiring Cisco switch can fail and you need a strong warranty when you’re buying one. And, here’s why you need this warranty and how you should use one:
1. A Cisco switch is equipped with LEDs on system components, which will flash green when everything’s a-OK. However, if the LED lights conk out, there’s no way of telling if all the components are working. You need a Cisco switch warranty to cover these little indicators that can make such a huge difference.
2. The “Show System” command on a Cisco switch system operating software must be operated regularly for system failures. The Show System module clues an IT network manager about the uptime and system failures. This can help the IT network manager figure out problem areas in the switch and invoke the warranty, when necessary. Operational problems keep cropping up and therefore its best to know these and get them patched up with Cisco’s 24/7 support.
3. Then, all IT managers must keep an eagle eye on the “Show Test” module of the system operating software. If this module comes across any hardware that is not functional, it displays an “F” next to the hardware component’s name. This test must be run regularly to take advantage of the Cisco’s 90-day material and workmanship warranty. In fact, the IT manager must stress test the Cisco switch and test to see if the hardware is robust or not.
4. The IT manager must also understand what’s going around inside the Cisco switch. He must run the “logging buffer” and check the “Message and Recovery Procedures” document. This document will indicate what failed, at what time, and whether it was a hardware or software crash. Though all Cisco switches are robust, there’s no telling when a piece of hardware can fail or when a software tool can crash. Therefore all IT network managers must stay on top on what’s going on inside the Cisco switch and invoke the warranty as required.
5. Sometimes multiple ports can create multiple problems even after the IT manager disables-enables them. Now, enabling-disabling ports on the Cisco switch can trigger other events that may cause glitches. As the IT managers keep shuffling between ports regularly, it makes sense to stress test the ports and replace the defective ports, if any.
6. The line cards in the chassis engine can fail and the pins in the Supervisor Engine can get bent. It’s best that these are replaced as per the warranty terms.
Though a Cisco switch is a prime product, it can fail, and there’s no telling when any hardware fails. Therefore, you need a warranty when you buy a Cisco switch.
