48-port Smart Managed PoE+ switch

The ZyXEL GS1900-48HPV2 is a rack-mountable smart managed switch with 48 Gigabit Ethernet ports. Twenty-four of those ports deliver PoE+ power up to 30 watts each within a total budget of 170 watts. Two SFP uplink slots provide fiber connectivity for backbone links. The switch targets small and medium businesses that need managed features such as VLAN, QoS and link aggregation without the complexity of a fully managed chassis.

Rack-mount metal chassis with dual mounting options

The unit measures 17.4 inches deep, 10.6 inches wide and 1.7 inches high in a 1U steel enclosure that fits standard 19-inch racks. It can also sit on a desktop thanks to its flat profile and rubber feet. All 48 RJ-45 ports and the two SFP slots face the front for tidy cable routing in a cabinet or on a shelf. The power supply is internal, so only a single IEC cord is required.

Smart fan cooling with 96.2-watt typical draw

A temperature-controlled fan adjusts speed automatically, staying near-silent at normal office ambient temperatures. Maximum operating temperature is rated at 122 degrees Fahrenheit. Typical power consumption is 96.2 watts while the PoE budget remains available for attached devices. The switch complies with RoHS and carries an environmentally friendly certification.

Questions about this item

What does the IEEE 802.3at PoE+ standard cap per-port power at on this switch?

The IEEE 802.3at PoE+ standard limits each powered port to 30 watts, and the GS1900-48HPV2 delivers up to that amount on its 24 PoE+ ports while staying within the total 170 W budget.

What physical space does the GS1900-48HPV2 need in a rack or on a desk?

The unit measures 17.4 inches long, 10.6 inches wide and 1.7 inches high (1U), weighs 7.83 pounds, and includes brackets for standard 19-inch rack mounting or rubber feet for desktop use.

How is the GS1900-48HPV2 initially configured, and which step do installers often miss?

Connect the switch to power, link a management PC to any RJ-45 port, log in to the web interface at the default IP, run the setup wizard for VLANs and PoE scheduling, then save the running configuration so settings survive a reboot.
