4. Plug the other end of the fiber-optic cable into one of the HBAs in the host (direct
topology) or into a switch (switch topology).
5. Attach a label to each end of the cable by using this scheme. A label is very
important if you need to disconnect the cables later to service a controller.
—
The host name and the host bus adapter (HBA) port (if direct topology)
—
The switch name and port (if switch topology)
—
The controller ID (for example, controller A)
—
The host channel ID (for example, host channel 1)
Example label abbreviation
– Assume that a cable is connected between port 1
in HBA 1 of a host named Engineering and host channel 1 of controller A. A
label abbreviation could be as follows:
Heng-ABA1/P1, CtA-Hch1
6. Repeat step 1 through step 5 for each host channel that you intend to use.
Step 5 –
Connecting the
Controller to a
Drive Tray The steps in this procedure describe how to attach Fibre Channel cables to a drive
tray. The steps for connecting other types of drive tray cables are similar, but they do
not require the installation of SFP transceivers.
1. If there is a black plastic plug in the drive port of the new controller canister,
remove it.
2. Insert an SFP transceiver into the drive port on a controller canister.
3. Plug one end of the cable into the SFP transceiver.
4. Plug the other end of the cable into the appropriate in port or out port on the
environmental services module (ESM) in the drive tray as applicable for your
cabling configuration.
5. Attach a label to each end of the cable by using this scheme. A label is very
important if you need to disconnect the cables later to service a controller.
—
The controller ID (for example, controller A)
—
The drive channel number and port ID (for example, drive channel 1, port 2)
—
The ESM ID (for example, ESM A)
—
The ESM port ID (for example, In, Out, 1A, or 1B)
—
The drive tray ID
Example label abbreviation
– Assume that a cable is connected between drive
channel 1, port 2 of controller A to the out port of the left ESM (A) in drive tray
1. A label abbreviation could be as follows:
CtA-Dch1/P2, Dm1-ESM_A (left), Out
6. Repeat step 1 through step 5 for each drive tray.
7. Remove the antistatic protection.
