WS-X4712-SFP-E - Cisco Catalyst 4500E Series SFP Line Cards Overview
WS-X4712-SFP-E - Cisco Catalyst 4500E Series SFP Line Cards is a genuine modular capacity expansion product from Cisco, a global name in networking whose platforms are used by enterprises, service providers and data-center operators alike. Belonging to the Cisco Catalyst 4500E Series family, the WS-X4712-SFP-E unit is built to the original factory specification, so it integrates with existing Cisco deployments predictably and behaves exactly as the platform documentation describes. In the network, it is installed into a compatible chassis slot, where it works alongside the supervisor and line cards to extend the platform’s capabilities.
From a specification standpoint, it offers 12 ports for client, server or uplink connectivity. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Cisco hardware already running in the environment.
Typical deployments include short-reach data-center interconnects, campus backbone fiber links, and carrier access and metro networks. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “Cisco Catalyst 4500E Series 12-Port GE (SFP)”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
