Answers

General

Q1. What is the Ethernet Pass-Thru Module?
A1. The Ethernet Pass-Thru Module is a sixteen port unmanaged data pass-through interconnection device that offers a one-to-one direct link between each BladeSystem server and a network device such as a switch. It is used when a data center already has an existing external network appliance to capture the individual uplinks from the blade servers.
Q2. Are cables included with the Ethernet Pass-Thru Module?
A2. No. Since each installation is different, cables are not included and must be purchased separately.
Q3. Why does HP recommend that I purchase two Ethernet Pass-Thru Modules?
A3. While all Blade servers have a NIC providing a dedicated path to the first interconnect bay, supplying 16 non-blocking uplinks, HP recommends that a second Ethernet Pass-Thru Module be installed. Since each server has a minimum of two NICs on each blade, the addition of a second Ethernet Pass-Thru Module assures a redundant path to the network switch, router or bridge.
Q4. Does the Ethernet Pass-Thru Module accept both fiber and copper connections?
A4. No. The Ethernet Pass-Thru Module has RJ45 copper uplinks only. If your network requires a fiber connection then you will need either a switch module or Virtual Connect Module with fiber optic uplinks.
Q5. Can the uplink ports be set to operate at any speed other than 1Gb?
A5. No, The 1Gb Ethernet Pass-Thru module does not auto negotiate and will not accept commands to operate at any uplink speed other than 1Gb.

Warranty

Q1. What type of warranty and service comes with the Ethernet Pass-Thru Module?
