Installing the Ethernet Switch or Hub
For the part number for a ferrite core, see the Part Numbers topic of the Service
Information section of the NTL Support and Service Library.
Installing the Ethernet Switch or Hub
Install the Ethernet switch or hub using the documentation that came with the switch or
hub. You can position switches or hubs on a tabletop, under a table, or on a wall.
Connect the Ethernet Switch or Hub to the Server
Connect the Ethernet switch or hub to the server, using the setup configuration
illustrated in Figure 5-1 on page 5-11:
1. Connect one end of an Ethernet cable to the Ethernet port on the PMF CRU in slot
50 of group 01. (The group number appears on both sides of an enclosure.)
To make the connection, insert the RJ-45 plug on the cable into the RJ-45 jack on
the PMF CRU until the tab on the plug clicks into place. See Figure 6-2 on
page 6-6.
2. Connect the other end of this Ethernet cable to a port on the Ethernet switch or
hub.
Do not connect this Ethernet cable to the cascade port on the Ethernet switch or
hub. These ports are used for cabling additional switches or hubs. To determine
which ports to use, see the documentation that came with the switch or hub.
3. Connect one end of another Ethernet cable to the Ethernet port on the PMF CRU
in slot 55 of group 01. See Step 1.
4. Connect the other end of this Ethernet cable to another port on the Ethernet switch
or hub. See Step 2.
Caution. If you are using ProCurve 24-port (managed) Ethernet switches for your dedicated
OSM or TSM service LAN, you should configure the switch ports that are used for connecting
to PMF CRUs—and only those ports—to protect the services processors from possible
overload. See Configuring a ProCurve 24-Port Ethernet Switch on page D-48 for the
procedure. This procedure is not needed and does not apply to ProCurve 8-port (unmanaged)
switches.
Note. To maintain the EMC compliance of all NonStop S-series systems except the
S7000, the Ethernet cables must be equipped with a ferrite suppression component (ferrite
bead) built into one end of the cables. Install the Ethernet cables that connect PMF CRUs
to Ethernet switches or hubs with the ferrite-bead end of the cables connected to the PMF
CRUs. See Figure 6-2
on page 6-6.
