Ports; Management Connectivity; And 3500Yl-24G Switches - HP ProCurve 6600 Switch Series Technical Overview

The ASIC layout shown in Figure 8 for the data center focused 6600-24G-4XG switch adds an NGX ASIC to
provide a 10-Gb uplink capability to this switch model . Unlike the 3500yl-24G switch, where the yl 10-Gb
module is rear mounted, the 6600-24G-4XG switch moves the 10-Gb ports to the front of the switch for
simplified cabling .
Examining the Gigabit ports, the last four ports are dual personality, meaning they can be used as RJ-45
copper ports or mGBIC (or SFP) fiber ports . The 6600-24G-4XG switch offers four ports of 10-Gb using SFP+
port slots—instead of X2 slots used on earlier 10-Gb HP networking products . There is no CX4 option for these
SFP+ products, but HP networking offers a low-cost copper direct attach cable (or DAC) option that is based
on the Small Form Factor Committee (SFF-8431) standard . The DACs are essentially a preterminated cable
with SFP+ compatible transceivers . DAC products are available in 1-, 3-, and 7-m lengths, primarily for close
proximity connections to 10-Gb servers or other SFP+ switches, such as in the same server cabinet . The 6600
accessories portion of this guide provides further details about the direct attach options .
The fabric-switching capacity is listed the same as the 3500yl-24G switch, where we account for the added
NGX ASIC and its maximum capacity of 28 .8 Gbps of throughput . Table 2 compares the 6600-24G/24G-4XG
architectures to that of the 3500yl-24G and 2910al-24G switches .

Table 2: 6600-24G/24G-4XG switches vs. 2910al-24G and 3500yl-24G switches

Ports

• 24 10/100/1000Base-T RJ-45 connectors
• 4 dual-personality 1-GbE SFP (can be used in lieu of last 4 10/100/1000Base-T ports)
• 4 10-GbE SFP+ ports (10-GbE-only speeds)
• SFP and SFP+ slots are not interchangeable and only support HP networking-branded optics

Management connectivity

• DB-9 serial console port
