System Console Connection to a Secure Operations LAN
To take advantage of ISEE functionality, a second NIC (or USB ethernet adapter cable)
is used to connect the console to a secure operations LAN. To use ISEE, a web-based
alternative to modem dial-outs, see the ISEE for NonStop topic in the Service
Information section of the NTL Support and Service library to learn about ISEE
prerequisites and NonStop-specific details that you will need before downloading and
configuring the ISEE client from the HP Hardware Support Services Web. Authorized
service providers can see ISEE for NonStop-HP Internal on the NTL employee site.
Ethernet Cables
To make Ethernet connections for a dedicated service LAN, use Category 5 unshielded
twisted pair (UTP) 10Base-T cables with RJ-45 connectors.
Ethernet Switch Ports
Several procedures in this section involve connecting Ethernet cables to ports on the
Ethernet switch or hub. Do not connect an Ethernet cable to the cascade port
(sometimes called the uplink port) on the Ethernet switch or hub unless specifically
instructed to do so. These ports are used for cabling additional switches. To determine
which ports to use, see the documentation provided with the Ethernet switch or hub.
Installing Ferrite Cores
If any ServerNet adapter, PMF CRU, IOMF CRU, or IOM 2 CRU in the system
connects to a cable with an RJ-45 connector, you should install two ferrite cores on
that cable.
1. Find a place on the cable within 4 or 5 feet of the connection to the adapter or
CRU.
2. Attach the ferrite cores at that location:
The ferrite cores are split, and open up into two pieces. To install a ferrite core,
pass the RJ-45 cable through the core twice by wrapping the cable around the
core and then closing the core jacket around the cable.
Space the cores no more than 12 inches apart from each other on each cable.
If you don’t have enough ferrite cores:
1. Count the number of cables terminating in RJ-45 connectors that are connected to
every adapter in the system.
2. Multiply that number by 2.
3. Subtract from that number the number of ferrite cores included with the adapters.
4. That number is the quantity of ferrite cores to order.
