Management Options

The Cisco RPS 2300 (model PWR-RPS2300) and the Cisco RPS 675 (model PWR675-AC-RPS-N1=) support th e Catalys t

2975 switch.

Warning

Attach only the following Cisco RPS model to the RPS receptacle: PWR-RPS2300 , PWR675- AC-RPS -N1=.

Connec t the Cat alyst 2975 switch and the redundant power system to the same AC power source.

Cisco RPS 2300 and RPS 675

The Cisco RPS 2300 has two output levels: –52 V and 12 V with a total maximum output power of 2300

W. The Cisco RPS 675 has two out put levels : –48 V and 12 V with a total maximum output power

of 675

The RPS 2300 and RPS 675 are redundant power systems that can support six external network devices and provide power to one failed device at a time.

• The sequen ce in wh ich t he sw it ch es a re first powered o n mig ht affect the swit ch th at be co m es the

stack master.

• If you want a particular switch to be the stack master, power on that switch first. This switch

becomes t he stack master an d rem ain s th e st ack m aster until a m a s te r re- el ection is req u ired . A f ter 1

minute, power on the other switches in the stack.

• If you have no preference as to which switch becomes the stack master, power on all the switches

in the s tac k w ith in a 1 -minute t ime fr am e. These sw i tch es partici pa te in t he s tac k m ast er el ect io n . Switches powered on after the 1-minute timeframe do not participate in the election.

• Power off a switch before you add it to or remove it from an existing switch stack.

Installing an SFP Module

When installing SFP modules, observe these guidelines:

• Do not remove the dust plugs from the SFP modules or the rubber caps from the fiber-optic cable

until you are ready to connect the cable. The plugs and caps protect the module ports and cables from conta min atio n and am bie nt ligh t.

• Removing and installing an SFP module can shorten its useful life. Do not remove and insert any

SFP module more often than is absolutely necessary.

• To prevent ESD damage, follow your normal board and component handling procedures when

connecti ng ca bl es t o th e s w i tch a nd o th er d evic es .

Step 1 Attach an ESD-p reven tive w ris t s tr ap t o yo u r w r ist and to a b a re metal su rface. Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows that show the d irect io n of t he co n nec ti on , e it he r s en d or r ece ive (T X or R X ) .

Step 3 If the SFP module has a bale-clasp latch, move it to the open, unlocked position.

Chap te r 2 Switch Ins tallati o n

Step 4 Align the SFP module in front of the slot opening, and push until you feel the connector on the module

snap into plac e.

Step 5 If the module has a bale-clasp latch, close it. Step 6 For fiber-optic SFP modules, remove the SFP dust plugs and save. Step 7 Connect the SFP cables.

Figure 2-17 Installing an SFP Module

Step 1 Attach an ESD-p reven tive w ris t s tr ap t o yo u r w r ist and to a b a re metal su rface. Step 2 Disconnect the cable from the SFP module. For reattachment, note which cable connector plug is send

(TX) and which is receive (RX).

Step 3 Insert a dust plug into the optical ports of the SFP module to keep the optical interfaces clean. Step 4 If the module has a bale-clasp latch, pull the bale out and down to eject the module. If the bale-clasp

latch is obs t ru c t e d and yo u canno t u s e your finge r, us e a smal l, fl a t- b lade s cr ewdriver o r ot her lo ng , narrow in s trument to o pen the b ale-cla sp latch.

You can identify this situation because the port has many packet errors or the port constantly flaps (loses and rega ins l ink) .

• Examine or swap the copper or fiber-optic cable with a known, good cable.

• Look for broken or missing pins on cable connectors.

• Rule out any bad patch panel connections or media convertors between the source and the
