HPE OfficeConnect 1920 24G Switch JG924A

The HPE OfficeConnect 1920 24G Switch, part number JG924A, is a fanless 1U switch with 24 auto-negotiating 10/100/1000 RJ-45 ports (10BASE-T, 100BASE-TX and 1000BASE-T) and 4 SFP slots that run at 100 or 1000 Mbps (100BASE-FX and 1000BASE-X). One RJ-45 console port provides a limited command line. It mounts in an EIA standard 19-inch telco rack or equipment cabinet, and the mounting hardware is included.

Switching and routing capacity is 56 Gb/s, with throughput of 41.7 Mp/s on 64-byte packets. Latency is under 5 µs at both 100 Mb and 1000 Mb. The MAC address table holds 8192 entries and the routing table holds 32 IPv4 and 32 IPv6 entries. A MIPS processor at 500 MHz works with 32 MB flash, 128 MB SDRAM and a 512 KB packet buffer, and MTBF is 120.48 years.

The chassis measures 4.4 x 44 x 17.3 cm (1.73 x 17.32 x 6.81 in) and weighs 2.25 kg (4.96 lb). Input is 100 - 240 V ac at 50/60 Hz with a maximum power rating of 19 W. With no fan fitted the switch makes no fan noise, and it is rated for altitudes up to 5 km. Storage and non-operating conditions are -40° to 70°C at 10% to 95% relative humidity, non-condensing.

The same 1920 series covers the 8G (JG920A), 16G (JG923A), 24G PoE+ 180 W (JG925A), 24G PoE+ 370 W (JG926A), 48G (JG927A) and 48G PoE+ 370 W (JG928A) models. Spare numbers for the JG924A switch are JG924-61001 and JG924-61101, and related spares are the 1U mount angle 5185-9360 and the console port serial cable 5184-6719 (1.8 m, RJ-45 to DB-9). Other OfficeConnect 1920 sizes sit in HPE switches.
