1.11.1 Chassis and Slots
I. Front view
The S7502 chassis uses an XG high-speed bus and XGbus is silkscreened on the
chassis.
Power supply module slots, RESET button, COM port (for PoE management), console
port, 10Base-T/100Base-TX management port and its status LED, fan LED, and card
status LED are in sequence arranged on the front panel.
The S7502 chassis provides two horizontal slots. An SRPU is required in slot 0 and
does not support active-standby switchover), while an LPU is optional in slot 1..
Figure 1-26 illustrates the front view of an S7502, where an LS81TGX2 is inserted in
slot 0 and slot 1, respectively. The LS81TGX2 in slot 0 serves as an SRPU, while the
LS81TGX2 in slot 1 serves as an LPU.
