J9138A Overview<\/p>\n
The HP ProCurve J9138A (E2520-24-PoE) is a 24-port managed Fast Ethernet switch with PoE (Power over Ethernet) capability, designed for enterprise access-layer deployments where connectivity and power delivery to devices such as IP phones, wireless access points, and security cameras are required. It provides 24 x 10\/100Base-TX RJ-45 ports for standard Fast Ethernet connections, along with 2 dual-purpose Gigabit ports that can operate either as 10\/100\/1000Base-T copper ports or as SFP fiber ports, enabling flexible uplinks to distribution or core networks.As a Layer 2 managed switch, the E2520-24-PoE supports VLANs, Spanning Tree Protocol (STP), link aggregation (LACP), Quality of Service (QoS), and advanced security features such as 802.1X authentication, ACLs, and port security.<\/p>\n","protected":false},"featured_media":24209,"comment_status":"closed","ping_status":"open","template":"","meta":{"_acf_changed":false},"product_brand":[504],"product_cat":[2913,332],"product_tag":[2946,3194,300,2942],"class_list":["post-24208","product","type-product","status-publish","has-post-thumbnail","product_brand-hp","product_cat-hp-network-switch-network-switches","product_cat-network-switches","product_tag-1000base-t","product_tag-2x-sfp","product_tag-hp","product_tag-switch","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"\n
