Table 44 describes the 6-Gb/s SAS port LEDs.
Management (RJ-12) port connector
Note: The management Ethernet (RJ-12) LCC to SPS port connector is not used at this time.
Figure 68 shows the management port (labeled with two symbols; one depicting a
telephone handset with a line through it and the other depicting a battery). The
telephone handset with a line through it symbol means that you cannot connect
telephone type circuits to this connector (see the following WARNING). This port
connects the LCC (A and B) ports to the SPS (A and B) ports, respectively.
The SPS (RJ-12) port is a LAN port not a WAN port. LAN ports contain safety
extra-low voltage (SELV) circuits, and WAN ports contain telephone-network
voltage (TNV) circuits. An RJ-45 (or TNV-type) looks the same as the RJ-12 except for
two very important differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a
six-wire modular jack. The RJ-45 plugs and jacks are wider than their RJ-12
counterparts - 7/16"vs 3/8". An RJ-45 plug won't fit into an R-J12 jack. But an RJ-12
plug will fit into an RJ-45 jack. Use caution when connecting cables. To avoid
electric shock, do not attempt to connect TNV circuits to SELV circuits.
Figure 68 LCC RJ-12 port
The cable connecting the LCC to the SPS is an RJ-12 to RJ-12. It has an RJ-12 adapter
(LCC side) on one end and a RJ-12 (SPS side) adapter on the other end.
LCC enclosure ID (enclosure address) and bus ID
On the rear of the LCC (A and B), an LCC enclosure ID indicator is provided. This ID
indicator is a seven-segment LED display for displaying decimal numbers. The LCC
enclosure ID appears on both LCCs (A and B) which is the same ID number. The
enclosure ID is set at installation (Figure 69 on page 72).
Each LCC includes a bus (loop) identification indicator. This indicator includes two
seven-segment LED displays for displaying decimal numbers. The SP initializes the
bus ID when the operating system is loaded (Figure 69 on page 72).
