RAID Levels Explained: RAID 0, 1, 5, 6, 10, 50 and 60 for Business Servers
RAID levels appear in nearly every storage decision, usually as though everyone already knows why RAID 6 beats...
Cisco Catalyst switches from Doha stock, including 48-port Gigabit PoE+ models from the Catalyst 2960-X and 3850 families, new and refurbished, for access networks in offices and campuses across Qatar.
This range covers Cisco Catalyst switches for the access layer, where desks, IP phones, cameras and wireless access points join the network. Current families are the Catalyst 2960-X and Catalyst 3850, in 48-port Gigabit configurations with PoE+ to power attached devices. Both are managed switches, configured through the familiar Cisco IOS command line, and both take SFP-based uplinks to reach the rest of the network.
They suit organisations in Qatar that standardise on Cisco, and integrators adding or replacing switches in an existing wiring closet or stack, where matching the installed hardware keeps configuration and spares simple.
| Factor | Why it matters |
|---|---|
| PoE budget | PoE+ supplies up to 30 W per port, but all ports share one budget that depends on the power supply fitted |
| Uplinks | The uplink ports and optics decide how fast the switch talks to the core |
| Routing | Some models route between VLANs themselves; others are mainly Layer 2 and hand routing to a core switch or router |
| Stacking | Stackable models are managed as one logical switch, but members need matching families and software |
| Feature licence | The licence level determines which routing and security features can be switched on |
Other PoE options are in PoE switches, and uplink optics in SFP modules and transceivers.
Replacing a failed unit or extending a stack is the most common reason to buy a refurbished Catalyst. Send the team the output of show version from a switch already in service. That shows model, software and licence level, so ServerDove can match a unit that joins cleanly. Do not assume two switches with similar names will stack together.
Switches ship from Doha, with delivery across Qatar typically in one day. Each refurbished switch is tested before it is listed. Racking, patching and base configuration are available as a service. For other Catalyst models or quantities, see the wider Cisco networking range or use the contact page.
The range holds 48-port Gigabit PoE+ switches from the Cisco Catalyst 2960-X and Catalyst 3850 families, new and refurbished, in Doha. Other Catalyst models, port counts and uplink options can be sourced on request. Send the model you have in mind, or describe the site, and the team will quote.
Both appear here as 48-port Gigabit PoE+ access switches, but they are different families. They differ in software platform, routing capability, stacking and uplink options, and a given unit's features also depend on its licence level. Tell the team what the switch must do, such as inter-VLAN routing or joining an existing stack, and they will point you to the right one.
Often, provided the new switch belongs to a family that stacks with yours and runs compatible software and licensing. Send the show version output from a current stack member so ServerDove can check before you order. Stacking also needs the correct stack cables and, on some models, stack modules.
PoE+ (IEEE 802.3at) delivers up to 30 W per port at the switch. The total across all ports is limited by the power budget, which depends on the power supply installed. Add up the maximum draw of your phones, cameras and access points and compare it with the budget before choosing a model.
Some switches accept only optics coded for that vendor, and others will run third-party modules with limited support. To avoid a port that will not come up, tell the team your switch model and the link type, and ServerDove will source optics that suit it.
Yes. Every refurbished switch is tested before it is listed, and it is covered by the ServerDove warranty. Extended warranty can be quoted on request if your organisation needs longer cover for a network refresh. If a switch is going into a critical closet, ask about keeping a spare unit on the shelf as well.
