Which Cisco 1921 router should I choose?

Question: I want to use Cisco 1921 router 1921/K9. And the bandwidth should meet 10MB.

I have PPPoE internet connection from my ISP and its terminating on (Optical Network Terminal) device. I want to connect RJ45 from my ONT to Cisco 1921 router, so that i can use my router as PPPoE dialer andas well asgiving internet to other users in my network. Any Cisco 1921 meet the need?

Answer: First, the 1921 has two HWIC ports.  You can stick a one-port HWIC-1FE two-port HWIC-2FE FastEthernet card (maximum ONE per appliance).  If you want GigabitEthernet, then you can use EHWIC-1GE-SFP-CU (maximum ONE per appliance).   The modules stated here are Layer-3 capable.  If you want a Layer-2 capable then read on.

The CISCO1921/K9 is a good one for you. Cisco 1921 price And as I know, there is some discount news on 3anetwork.com, 56% off, US$525.00. Refer to here for more.

CISCO 3750 VS 3560 What is the difference between them?

The main difference is that the Cisco Catalyst 3750 supports Cisco StackWise, i.e. creating one large virtual switch out of multiple chassis.  The 3650 has a “cluster” feature which while it sounds close, just means that you can control multiple switches from a single one.

The Cisco 3750 Series Catalyst v2 are next-generation energy-efficient Layer 3 Fast Ethernet stackable switches. Cisco 3750 Series switches support Cisco EnergyWise technology, which helps companies manage the power consumption of their network infrastructure and network-attached devices, thereby reducing their energy costs and carbon footprints.
The Cisco Catalyst 3750 v2 Series consumes less power than its predecessors and is the ideal access layer for enterprise, retail, and branch-office environments. It increases productivity and provides investment protection by helping enable a unified network for data, voice, and video.

Catalyst 3750 VS 3560

When it comes to the Cisco 3750E vs 3750X, The X offers what Cisco is calling StackPower, the ability to share power loads between multiple switches.  This is a beneficial feature when it comes to PoE+.  StackPower allows up to four members of the same StackWise group to combine their power supplies into one large virtual power supply.  It also allows some of the power supplies to be taken offline, increasing efficiency.

For building out small to medium offices these two features are quite valuable.  Start with one switch and add on with little to no disruption, while only using the power needed.

Cisco 2960: solution of the flash is deleted

First, we need to have the IOS file, glc-lh-smd if no backup the original file, you can find the same version ofIOS to replace.

I have tried a method, when Flash is deleted, restart can not enter the system, you can use X-Modem to restore it. I accidentally deleted a Cisco2950 switch Flash IOS at that time,causing the system to be unable to start, get a conclusion on many data: the only way to recover by X-Modem. The recovery method of my:
