NOTE
The card dimensions are defined as follows:
l Depth: the distance between the top of an ejector lever and the end of PCB
l Width: the longest distance between the tops of two ejector levers
l Height: the height of the front panel
Figure 5-3 shows a typical card supported by the AR routers, and Table 5-2 lists the card
dimensions.

5.1.3 Port Numbering
On an AR router, interfaces are numbered in the format of slot ID/subcard ID/interface
sequence number.
l Slot ID
The slot ID identifies in which slot a card is installed.
NOTE
When two slots need to be combined into one slot, the larger slot ID is used as the new slot ID. For
example, when slot 1 and slot 2 are combined, slot ID 2 is used as the new slot ID.
l Subcard ID
The subcard ID specifies the ID of a subcard. AR routers do not support subcards, so the
subcard ID is fixed at 0.
l Interface sequence number
The interface sequence number indicates the position of an interface on a card.
– If there is only one row of interfaces on a card, the interfaces are numbered from
left to right, starting with 0.
