Question about installing PA-2T3+ on a Cisco 7507

Unanswered Question
Jan 21st, 2008

Hi Sir,

My current network has a Cisco 7507 with two RSP4.

I'm planning to add a PA-2T3+. There's a VIP2-50 in Slot 4 and port 1 (bay 1) is empty. Can I insert the PA-2T3+ there?

Is there any constraint such as bandwidth point like the 7200 series? I'm not familiar with 7500 series.

What's the part number of the cable for PA-2T3+?

Please advise.

Thank you.

B.Rgds,

Lim TS

I have this problem too.

Hi Lim,

Kindly check the below links, you should use VIP2-40 or higher, up to four T3 ports can be operated simultaneously on each VIP (up to three T3 ports per VIP2, with each port running at T3 clock rate, while up to four T3 ports per VIP2, with subrate clocking enabled).

The only constrain with the 7500 router is aggregate bandwidth for the dual CyBus, you should consider this when populating your router with VIPs - the Cisco 7507 has two CyBuses (called the dual CyBus) for an aggregate bandwidth of 2.134 Gbps (1.067 Gbps each), the 7507 dual CyBus has seven slots: interface processor slots 0 and 1 (CyBus 0), RSP slots 2 and 3, and interface processor slots 4 through 6 (CyBus 1), you must consider this when populating your router (you should consider this issue mainly if you've installed a GigaEthernet interface).

As for the cable you should use CAB-ATM-DS3/E3=.
