Installing a card
CAUTION:
The LST1XP32REB1 and LST1XP32REC1 have three circled areas marked with HAND OPERATION AREA
(see
Figure 29 ) on their print circuit board. You can touch these areas when holding the card. Touching
any area outside these three areas might result in damage to the LPU.
On an S12504, install at least one MPU, one LPU, and three switching fabric modules. On an S12508
or S12518, install at least one MPU, one LPU, and seven switching fabric modules.
The S12500 does not support intermixing of the MPU, LPU, and switching fabric modules.
Use one of the following positions to install the card:
• Install MPUs, Ethernet interface cards, and OAA cards at the front of the switch chassis. Slot 0 and
Slot 1 are for MPUs and other slots (slots 2 to 5 for the S12504, slots 2 to 9 for the S12508, and
slots 2 to 19 for the S12518) are for Ethernet interface cards and OAA cards.
• Install switching fabric modules in the switching fabric module slots (slots 6 to 9 for the S12504,
slots 10 to 18 for the S12508, and slots 20 to 28 for the S12518) at the rear of the chassis.
