Upgrade 2424M to GB?

Hey, all--

I was given an old HP ProCurve 2424M. I downloaded documentation from the HP site, updated the firmware and some basic configuration settings. Voila! it's working fine in my basement.

Since the rest of my house is using Gb NICs and switches, I was wondering if it's possible to upgrade the 2424M to 10/100/1000. I've seen stacking modules and fiber-optic interfaces for the 2424M, but it's unclear to me whether the addition of a module would upgrade all the ports on the 2424M to Gigabit speed.

Is the Gigabit SX Module (HP J4113A) what I need? It seems like $100 would be a pretty inexpensive upgrade for 24 ports of Gigabit.

Thanks!

~~~~~~~~~~~~~~~~~~~~~~~

I'm looking at the back of my 2424M, and it does have a module slot. In addition, the document "Software Update C.09.30 Release Notes for the HP ProCurve Switches 1600M, 2400M, 2424M, 4000M, and 8000M" describes modules that can be installed into the 2424M, including the J4115B. Here's a snip from Page 91:

Q: Does the HP ProCurve Switch 2424M support stacking?
A: The HP ProCurve Switch 2424M has a slot for the two port HP ProCurve Switch 2424M Gigabit
Stacking Module (product number J4130A). This module stacks up to 7 switches with the HP
ProCurve Switch 2424M Gigabit Stacking Kit (product number J4116A). One stacking module must
be purchased for each switch and one stacking kit must be purchased for every stack of two switches.
The stacking module can also be used as a dual gigabit uplink module with the HP ProCurve Gigabit-
SX Transceiver (product number J4131A) and/or the HP ProCurve Gigabit-LX Transceiver (product
number J4132A). In addition, the following modules, which are supported in the HP ProCurve Switch
8000M, 4000M, 2400M, and 1600M, are also supported in the HP ProCurve Switch 2424M for uplink
connectivity or for additional desktop ports:
■ HP ProCurve Switch 100/1000Base-T Module (product number J4115A and J4115B)
■ HP ProCurve Switch 10/100Base-T Module (product number J4111A)
■ HP ProCurve Switch 100Base-FX Module (product number J4112A)
■ HP ProCurve Switch Gigabit-SX Module (product number J4113A)
■ HP ProCurve Switch Gigabit-LX Module (product number J4114A)
■ HP ProCurve Switch 10Base-FL Module (product number J4118A)

Q: What are the features of the HP ProCurve Switch 100/1000Base-T Module?
A: The HP ProCurve Switch 100/1000Base-T Module (J4115A and J4115B) is an accessory that can
be added to the HP ProCurve Switch 1600M, 2424M, 4000M, and 8000M. The HP ProCurve Switch
100/1000Base-T Module provides one twisted-pair port with an RJ-45 connector for 100Mbps or
1000Mbps (Gigabit) operation over category 5 cable. Like all of the switch modules available for this
line of products, the HP ProCurve Switch 100/1000Base-T Module is shipped ready for network
operation as soon as a viable network cable is connected. The LEDs on this module provide
information on the link status, network activity, connection bandwidth, and communication mode
(half or full duplex). And, as with all other HP ProCurve modules, it features "hot-swap" operation,
meaning addition or replacement of a module can be achieved without having to shut down the switch
(changing the module type in a given slot does require a switch reset).
~~~~~~~~~~~~~~~~~~~~~~

So again, my amended question is: If I install the J4115B and install the proper HP software updates, will the 24 ports in my 2424M communicate at GB speed?

Thanks again for your help.

:hello:

The simple answer is no, they will not. Only two modules on that list give you twisted pair Ethernet connectivity, J4115A and J4115B. These two modules are single port modules and support a single (1!) port of gigabit connectivity. If you switch supports two modules, then you will get two (2) ports of gigabit connectivity, in addition to the 24 ports of FastEthernet connectivity, giving you a total of 26 ports, 24 FastEthernet and 2 Gigabit.

The module looks like this, and costs about $30USD per module:

A true 24 port Gigabit switch will run you about $200 new:

The HP ProCurve J9450A (24 port, 10/100/1000) currently lists for $269 at the link listed above. It's fanless, lightweight, and comes with rackmounts. Given the reliability of the HP 2424M that I am replacing, I chose another HP over less expensive consumer-oriented products because I expect it will have a longer shelf life.

Thanks, sk1939 for your input.

No problem, glad to have helped. For our clients that don't have the want or budget for Cisco or Juniper equipment, we use HP ProCurves, they are fine switches.
