Four of the following service cards can be installed: 1000M Interface Card GE/10GE Interface Card 10GE Interface Card 25GE Interface Card 40GE/100GE Interface Card 100GE Interface Card NOTE: The cards supported by a switch depend on the software version. For details, see Hardware Query Tool. 3. Two SFUs 4. A pair of mounting brackets NOTE: The mounting brackets are used to secure the chassis in a cabinet. 5. Four power modules 6. Two CMUs 7. Front ESD jack NOTE: The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded. 8. Cable management frames NOTE: The cable management frames separate cables on different cards and help route cables orderly. S12700E-4 chassis structure (rear view) 1. Two Fan Module 2. Rear ESD jack NOTE: The ground terminal of an ESD wrist strap can be inserted into this jack. The ESD wrist strap can provide ESD protection when the chassis is reliably grounded. 3. JG ground terminal NOTE: The two-hole OT terminal of a ground cable can be connected to the screws to ground the chassis. 4. Air filter NOTE: The air filter prevents dust from entering the chassis. 5. A pair of removable handles NOTE: You can install these handles on two sides of the chassis to lift the chassis. - - - Specifications of the S12700E-4 series switches Item Description Number of LPU slots 4 Number of MPU slots 2 Number of SFU slots 2 Number of fan slots 2 Number of power module slots 4 Number of CMU slots 2 Port density per chassis 192xFE, 192xGE, 192x10GE, 160x25GE, 96x40GE, 96x100GE Installation The switch can be installed in an N66E or N68E cabinet, one cabinet for one or two chassis.
