Introducing the Switch
The 2910al-24G Switch and 2910al-48G Switch have respectively, 24 or 48,
auto-sensing 10/100/1000Base-T RJ-45 ports, four dual-personality ports—
either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC, and two slots are
provided in the back of the device to support expansion modules:
■ 2-port (two fixed CX4 ports) 10 Gigabit per second Ethernet (10-GbE)
module.
■ 2-port 10-GbE SFP+ (Small Form Factor Pluggable) module. The specifi-
cation for SFP+ defines the physical and electrical characteristics of this
form-factor (size and shape). The form-factor is identical to SFP, but the
SFP+ is a 10-Gigabit Ethernet transceiver.
■ 1-port 10-GbE interconnect module.
Table 1-1. These products support optional network connectivity with the
following speeds and technologies:

For supported transceivers see www.procurve.com/faqs. Both ProCurve 10-GbE trans-
ceivers and ProCurve Mini-GBICs and SFPs have links to a list of supported products
(first question in the “General Product Information” category).

ogy Information”.
